    • "The second approach aims to develop a dual wavelength source that can be fabricated on a Generic InP-based technology platform to access the cost reduction of a multi-project wafer run. This approach, limited by the building blocks available on the platform [12], developed a dual wavelength arrayed waveguide grating (AWG) laser structure. These were initially proposed for wavelength division multiplexed sources since they are able to deliver multiple wavelengths, with fixed frequency spacing, defined by the AWG (usually Δλ ß 100 GHz).

    ABSTRACT: This paper describes the advantages that the introduction of photonic integration technologies can bring to the development of photonic-enabled wireless communications systems operating in the millimeter wave frequency range. We present two approaches for the development of dual wavelength sources for heterodyne-based millimeter wave generation realized using active/passive photonic integration technology. One approach integrates monolithically two distributed feedback semiconductor lasers along with semiconductor optical amplifiers, wavelength combiners, electro-optic modulators and broad bandwidth photodiodes. The other uses a generic photonic integration platform, developing narrow linewidth dual wavelength lasers based on arrayed waveguide gratings. Moreover, data transmission over a wireless link at a carrier wave frequency above 100 GHz is presented, in which the two lasers are free-running, and the modulation is directly applied to the single photonic chip without the requirement of any additional component.

    • "As constant improvements in the performance and fabrication yield of photonic integrated circuits is observed [12], there is enough evidence that monolithic photonic integration could offer advantages in terms of a significant reduction in the system footprint, inter-element coupling losses, packaging costs, and system power consumption thanks to the use of a single cooler for multiple functions. Moreover, advances and decreasing fabrication cost in photonic integration have been triggered by the recent availability of numerous generic fabrication platforms [13], thus simplifying the development of advanced integrated photonic systems. 0733-8724 © 2014 IEEE.

    ABSTRACT: We present a review of the critical design aspects of monolithically integrated optical phase lock loops (OPLLs). OPLL design procedures and OPLL parameters are discussed. A technique to evaluate the gain of the closed loop operating system is introduced and experimentally validated for the first time. A dual-OPLL system, when synchronised to an optical frequency comb generator without any prior filtering of the comb lines, allows generation of high spectral purity signals at any desired frequency from several GHz up to THz range. Heterodyne phase locking was achieved at a continuously tuneable offset frequency between 2 and 6 GHz. Thanks to the photonic integration, small dimensions, and custom-made electronics, the propagation delay in the loop was less than 1.8 ns, allowing good phase noise performance with OPLLs based on lasers with linewidths less than a few MHz. The system demonstrates the potential for photonic integration to be applied in various microwave photonics applications where narrow-bandwidth tuneable optical filters with amplification functionality are required.

    • "Recent technological advances in high speed backbone networks and optical telecommunications, fueled by the growing demand for bandwidth hungry applications, have been driving the quest for photonic circuits capable of delivering high speed signal processing functionalities [1],[2]. Steadily maturing photonic integration technologies of improved yield [3]-[5] have led to impressive demonstrations of functional complex circuits [5] and switching architectures [6]-[8], making firm steps towards Medium-Scale (MS) Photonic Integrated Chips (PICs). In this effort, Semiconductor Optical Amplifiers (SOAs) constitute key-signal processing elements due to their proven credentials of high-speed all-optical switching and enhanced maturity level [2], to the point where a plethora of commercial devices are already available.

    ABSTRACT: A time-domain solver for the response of a Semiconductor Optical Amplifier (SOA) relying on multigrid numerical techniques and a wideband steady state material gain coefficient is presented for the first time. Multigrid techniques enable the efficient solution of implicit time discretization schemes for the associated system of coupled differential equations, namely the carrier rate equation in the time domain and the signal amplification in the spatial domain, which in turn enable accuracy- instead of stability-restricted time-discretization of the signals. This allows lifting off the limitations of an equidistant spatio-temporal grid for the representation of the incoming signals adopted by traditional explicit SOA models, releasing an adaptive stepsize controlled solver for the dynamic SOA response with dense timesampling under a rapidly varying SOA signal output and scarce time-sampling when negligible changes are observed.
