Design of photonic crystal devices
The subject of this PhD thesis is the study of photonic crystal waveguides that incorporate discontinuities or structural fabrication-induced variations. For the numerical study of these devices the mode matching (MM) method is proposed. The comparison of the MM method with the couple mode theory (CMT) showed that the CMT can provide only a first approximation to the perturbation-induced scatte...
متن کاملDesign of low-dispersion fractal photonic crystal fiber
In this paper, a fractal photonic crystal fiber (F-PCF) based on the 1st iteration of Koch fractal configuration for optical communication systems is presented. Complex structure of fractal shape is build up through replication of a base shape. Nowadays, fractal shapes are used widely in antenna topics and its usage in PCF has not been investigated yet. The purpose of this research is to compar...
متن کاملDensity of modes maps for design of photonic crystal devices
In the paper, we present numerical results on characterization of transmitting properties of wideband filters based on linear and nonlinear photonic crystals confined with the waveguide. Novel characteristics of the PhC filters such as density of modes maps and transmission maps are computed, and their efficiency is analyzed. Presented characteristics can be used as an auxiliary optimization to...
متن کاملDesign of Photonic Crystal Polarization Splitter on InP Substrate
In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...
