• ##### Article: Improved dispersion tolerance of Miller coding by integrating duobinary coding
[Hide abstract]
ABSTRACT: A Miller–Duobinary coding scheme is proposed to increase optical transmission distance by compressing the optical spectrum compared with that of Miller coding and thereby demonstrating much larger tolerance against fiber dispersion. In this modulation scheme we investigate the dispersion tolerance of this code and found it to be nearly twice that of Miller coding only by employing single photodetector at 1 dB power penalty. The transmission reach can further be extended for higher power penalty. The circuit complexity of the proposed scheme is comparable to traditional Duobinary coding. The dispersion tolerance of Miller–Duobinary code obtained at 3 dB power penalty is $$-971$$ to $$+964$$ ps/nm.

• ##### Article: Design and evaluation of a reflectance diffuse optical tomography system
[Hide abstract]
ABSTRACT: We have designed a continuous wave, back-reflection diffuse optical tomography system; and developed a new practical calibration method including both optode efficiency and positional error corrections. System design, data acquisition and calibration protocols are described in detail. Monte Carlo (MC) simulations of photon distribution for tissue phantoms have been used to obtain the weight matrix to be used in the Rytov approximation to the photon diffusion equation. The system has been evaluated by acquiring data from a tissue phantom with a background scattering coefficient ( $$\upmu _{\mathrm{s}}^{\prime }$$ ) of $$10\,\hbox {cm}^{-1}$$ and absorption coefficient ( $$\upmu _{\mathrm{a}})$$ of $$0.04\,\hbox {cm}^{-1}$$ . An inclusion made of 1 % Intralipid and indocyanine green with $$\upmu _{s}^{\prime }=10\,\hbox {cm}^{-1}$$ and $$\upmu _{\mathrm{a}}= 0.16\,\hbox {cm}^{-1}$$ was placed at a 2 cm depth from the tissue phantom surface. After calibration, the average value of the measurements over source–detector pairs at the same distance for each neighborhood was calculated. Perturbation data were obtained by subtracting the average data from the measurements with the same source–detector separation. In the reconstruction, weight matrixes obtained from MC simulation for $$\upmu _{\mathrm{s}}^{\prime }= 7$$ to $$12\,\hbox {cm}^{-1}$$ were used. The Depth Compensation Algorithm was used in the Tikhonov regularization to identify the location of the inclusion correctly in the reconstruction.

• ##### Article: De-multiplexing based on complex ICA for mode group diversity multiplexing system
[Hide abstract]
ABSTRACT: In order to mitigate the crosstalk in mode group diversity multiplexing (MGDM) system, the fixed-point complex ICA algorithm (T-CMN) based on negative entropy maximization is proposed to implement de-multiplexing in a 2 $$\times$$ 2 MGDM system in which two QAM signals are transmitted. The performance of this algorithm is compared with the DD-LMS (Decision-directed Least Mean Square Algorithm). The results indicate that the T-CMN algorithm separates the signals successfully and achieves a better de-multiplexing performance than DD-LMS.

• ##### Article: Numerical and experimental investigations of micro-integrated external cavity diode lasers
[Hide abstract]
ABSTRACT: We report the results of numerical and experimental investigations of the electro-optical behaviour of an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an optical feedback. The travelling wave model was used to simulate and analyse the nonlinear dynamics of the considered laser device. Different modelling approaches for gain and refractive index change functions have been considered. It is shown, that the simulated behaviour of the electro-optical characteristics is in good agreement with experiments.

• ##### Article: Charge sensitivity simulation on a double barrier GaAs/InGaAs/InAs quantum dot-in-well hybrid structure photodetector
[Hide abstract]
ABSTRACT: In this paper we simulated a photodetector based on a double barrier GaAs/InGaAs/InAs quantum dots–quantum well hybrid structure, calculated its I–V and C–V characteristic and studied the electronic states of the self-assembled InAs quantum dots embedded in InGaAs and GaAs quantum wells. By optimizing the device structure, ultrahigh sensitivity was obtained. We attributed this high sensitivity to the double barrier structure that effectively lowered dark current. This simulation method can be used to designing and optimizing devices with similar structure.

• ##### Article: Nanoporous silicon microcavity based optical sensor to detect adulteration of petrol by organic solvents
[Hide abstract]
ABSTRACT: Adulteration of petrol by organic solvents is rampant across the globe. Here we present a novel sensor to detect adulteration of petrol by three organic solvents, namely toluene, xylene and benzene. The sensor is a nanoporous silicon microcavity structure that is sensitive to the variations in the refractive index of the fuel samples. The several useful properties of porous silicon such as its simple fabrication process, high sensitivity, compatibility with silicon microelectronics, room temperature operation, very high surface-to-volume ratio and biocompatibility make it a popular candidate for sensing applications. The primary objective of this work is to develop a novel porous silicon microcavity sensor that is capable of detecting the adulteration of petrol by the aforementioned organic solvents. This is achieved by the change in the reflectance spectrum of the microstructure when different concentrations of adulterated fuel samples are introduced in its pores, as a distinct red shift is produced for each concentration. The same sensor is utilized for sensing the adulteration by the three organic solvents. The sensing process was found to be reversible and hence the sensor is reusable.

• ##### Article: Wavelength-shift-free regenerator for 10 Gb/s RZ system on satellite by two-stage offset filter using HNLF and SOA
[Hide abstract]
ABSTRACT: Aiming at the characteristics of dynamic routing and limitation on power in satellite optical network, a wavelength-shift-free regenerative scheme based on two-stage offset filter is put forward. Making use of the property that the signs of chirp induced by self-phase modulation are opposite in semiconductor optical amplifier (SOA) and high nonlinear fiber (HNLF), the scheme imposes a red-shifted filter and a blue-shifted filter respectively on the signals after SOA and HNLF, which not only realizes a two-stage regeneration for signals, but also compensates the frequency offset and keeps the wavelength unchanging before and after the regenerator. The results show that the Q factor of signals can be improved 6 dB, and the timing jitter caused by one-stage offset filter can be suppressed effectively.

• ##### Article: The enhanced optical coupling in a quantum well infrared photodetector based on a resonant mode of an air–dielectric–metal waveguide
[Hide abstract]
ABSTRACT: The hybrid structure consisting of periodic gold stripes and an overlaying gold film is proposed to enhance the optical coupling of a quantum well infrared photodetector. An air–dielectric–metal waveguide is formed when the hybrid structure is integrated on the top of the quantum well detector with the substrate being removed. Finite difference time-domain method is used to numerically obtain the reflection spectrum and the field distribution of the waveguide. The results show that a strong electric field component is induced in parallel to the growth direction of quantum well when the waveguide resonant mode occurs at the detective wavelength of the quantum well infrared photodetector. The relationship between the structural parameters and the resonant wavelength is derived by using the effective refractive index method of the air–dielectric–metal waveguide. A high coupling efficiency can be obtained and the performance of the QWIP can be greatly improved.

• ##### Article: A novel method to reduce the period limitation in laser interference lithography
[Hide abstract]
ABSTRACT: This article presents a novel method to apply on reducing the period limitation in laser interference lithography (LIL) by preparing a kind of nanowire arrays with the period $${\uplambda }/(4\hbox {n}\times \hbox {sin}{\uptheta }$$ ) instead of $${\uplambda }/(2\hbox {n}\times \hbox {sin}{\uptheta }$$ ). Nanowire arrays with periods of 150 and 125 nm on Si (100) substrate were fabricated successfully with a 325 nm He–Cd continuous wave laser as a light source, based on the combined process of dry etching and wet etching. It is the slight over-etching in the dry etching process and keeping the fluorine carbon organic polymer layer intact during whole process of wet etching that guaranteed the nanowire generated from the platform between two adjacent etched facets. The width of the nanowire as narrow as 50 nm was fabricated by this method, which is much more interesting for the research on the small size effect. This method is proved to circumvent the period formula limitation of the traditional LIL and makes the preparation of nanostructures with much smaller size more feasible.

• ##### Article: Mathematical formulation for transparency and maximum scattering from bilayer MTM-coated PEC cylinders
[Hide abstract]
ABSTRACT: In this paper, a novel formulation interval to design multilayer metamaterial (MTM) radar absorbers and shields in cylindrical structure is presented. In this proposed approach, the interaction of electromagnetic waves by an infinitely long perfect conducting cylinder coated with bilayer MTM is investigated. Transparency and maximum scattering conditions for the structure, under a normally uniform plane wave with transverse electric, transverse magnetic and circular polarizations, are mathematically extracted by using small argument forms of Bessel and Hankel functions. In transparency, the capability of radars is dissipated by the full transmission of the incident waves back to the direction from which they were radiated. On the other hand, scattering maximization by diffuse reflection and making chaff, confuses the radars in target detection. Theoretical formulations are verified by COMSOL which is full wave software. However, our formulations are proved for electrically small cylinders, but simulation results show that they are useful for cylinders with dimensions compared to the wavelength.

• ##### Article: The approximating functions method for nonlinear Volterra integral equations
[Hide abstract]
ABSTRACT: An approximating functions method for solving a nonlinear Volterra integral equation is presented. The equation form is the same for various media and it does not depend on the initial signal. Other key features of this approach are the natural description of non-stationary and nonlinear phenomena, the unified definition of inner and outer problems and the inclusion of initial and boundary conditions in the same equation. It permits universal modelling algorithms for a wide range of nonlinear electrodynamic problems. A computer model based on the algorithm is developed for 1D + 1T case and the transformation of an electromagnetic pulse in a nonlinear layer is investigated.

• ##### Article: A wide-angle TE-polarization absorber based on a bilayer grating
[Hide abstract]
ABSTRACT: We report a wide-angle TE-polarization (electric field parallel to the grating strips) absorber based on a bilayer grating in the infrared regime. The simulation results show that the absorber can totally absorb the incident light in a wide angle, and the absorption magnitude for the angle range from 0° to 20° is larger than 0.99. We attribute the wide-angle advantage to the electric field isolation of the cavity resonance in the unit cell. The simulation results also show that absorption spectrum can be tuned by changing the geometric parameters. These characteristics are very important in manipulating and designing a wide-angle TE-polarization absorber.

• ##### Article: Enhanced light-extraction efficiency of GaN-based light-emitting diodes with hybrid Photonic Crystals
[Hide abstract]
ABSTRACT: The light-extraction efficiency (LEE) of GaN-based light-emitting diodes (LEDs) is strictly limited by total internal reflection (TIR) and Fresnel reflection. In this paper, we sought to utilize hybrid Photonic Crystals (PhCs) with different etched depth to increase the LEE of GaN-based LEDs. The results showed that the structure proposed here could decrease not only the TIR but also the Fresnel reflection. Three-dimensional rigorous coupled waves approach was employed to calculate the total transmission efficiency at different incident angles, and numerical simulations based on finite-difference time-domain method were carried out to explore mechanisms by which hybrid PhCs can effectively improve the LEE. This improvement is related to the grade-refractive-index effect and diffraction properties of the hybrid PhCs. And the structure proposed here provides a train of thought for the design of high efficiency LEDs.

• ##### Article: Analysis of direct current performance on N-polar GaN-based high-electron-mobility transistors for next-generation optoelectronic devices
[Hide abstract]
ABSTRACT: Exhibiting extremely high electric polarization, N-polar Group III-nitrides heterostructure has been widely used on high-electron-mobility transistors (HEMTs) and terahertz photodetectors in recent years. In this paper, we numerically investigated an N-polar GaN/AlGaN/GaN HEMT device in which the two-dimension electron gas is induced at the top GaN/AlGaN interface. Characteristics of the device were determined by using experimental data to calibrate the few adjustable parameters of our simulations. Effects of interface charges on the device were researched by changing the component of Al. In addition, the dependency of scaling the device dimensions on direct current (DC) output characteristics, such as the gate length and the barrier height was also analyzed in details. Our simulations showed that increases of Al mole fraction and AlGaN barrier height and a decrease of the gate length can improve the DC performance of HEMT device to some extent. That could be a significant guidance for designing or optimizing the structure of N-polar GaN-based devices.

• ##### Article: Performance analysis of QPSK in free-space optical communications systems over combined channel with phase compensation error
[Hide abstract]
ABSTRACT: Performance of free-space optical (FSO) links employed quadrature phase shift keying (QPSK) modulation with phase compensation error over Combined Channel is investigated in this paper. By considering the key factors of weather condition, pointing errors and phase noise, the closed-form expressions of symbol error rate (SER) are derived by employing the hyper-geometric functions substitution method. Numerical results show that for FSO system in Combined Channel, SER must be the trade off between pointing errors and weather condition, but it suffers more from the weather condition. The effects of pointing errors on system performance are also studied.
