High-Order Angle and Polarization Resolved Reflection of Artificial Opal Photonic Crystal

Design 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...

Photonic crystal multiple diffraction observed by angular-resolved reflection measurements

Angular-resolved reflection measurements suggest that higher-order Miller-index crystal planes of a fcc photonic crystal reflect specularly about the normal to the 111 planes. We suggest that this phenomenon results from a two-step diffraction process where light is first Bragg diffracted by higher-order Miller-index crystal planes and is then two-dimensionally diffracted by periodicities withi...

Photonic Crystal-Based Polarization Converter for Optical Communication Applications

A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...
