Localized surface plasmons (LSPs) are a potentially valuable property for the practical use of small size metallic particles. Exploiting the LSPs in metallic nanoparticle (NP)-based solar cells was shown to increase the efficiency of solar panels. A large extinction cross section of NPs allows for high scattering of light at the surface of the pane...

In this work, the determination of the masses of supermassive black holes (SMBHs) and the properties of their host spiral galaxies are focused for the purposes of constraining scaling relations and with the aim of understanding the role of SMBHs in the evolution of galaxies. The measurements of SMBHs mass for a sample of 40 spiral galaxies were stu...
Conference Paper
Plasmonic waveguides is a hot topic in the field of photonic devices due to the ability to provide signal propagation in nanoscales beyond the diffraction limit. Reducing the dimensions of optical components allows for increasing of integration density and reduce the cost of fabrication. In this paper, the dispersion characteristics of the Channel...
Article
Silicon is a widely used material due to its strong properties especially low loss and high nonlinearity in the wavelength range 1.2–6 μm. Also, photonic crystal fibers (PCFs) have been extensively involved in producing spectral light broadening in the literature. Here we report supercontinuum generation (SCG) over the wavelength range 1000–3000 nm...

In this paper, a novel design of silica photonic crystal fiber (PCF) is proposed and analyzed for supercontinuum generation (SCG). The suggested design has an As2S3 chalcogenide core region with large nonlinear coefficient and low anomalous dispersion. The modal analysis of the reported design is performed using full vectorial finite element method...
Article
In this paper, one stage nematic liquid crystal photonic crystal fiber (NLC-PCF) soliton pulse compressor is proposed and analyzed using full vectorial finite element method (FV-FEM). The suggested design has high birefringence due to the infiltration of the NLC material. Therefore, it can be used as a soliton pulse compressor for the two polarized...
Article
An ultra-compact polarization splitter based on dual core nematic liquid crystal silica photonic crystal fiber (NLC-PCF) is proposed and analyzed. The refractive index difference between the NLC and silica material guaranties the index guiding through the reported splitter. The dual core NLC-PCF has strong polarization dependence due to the birefri...
Article
Highly birefringent photonic crystal fiber (PCF) is proposed and analyzed using full vectorial finite element method. The reported design has a central large core filled with nematic liquid crystal (NLC) which provides tunability with the external electric field and temperature. In addition, the full permittivity tensor of the NLC material is taken...
