Analysis of integrated optics elements based on photonic crystals

چکیده
We present the design of a demultiplexer based on photonic crystals (PC). The control of the refractive index, periodicity, geometry and size of the structure, are very important to light propagation in PC. The demultiplexer is intended to separate pulse channels with 1.3 and 1.55 μm wavelength into wide pass band wavelength division multiplexing (WDM) optical telecommunications systems. The dependence of the band gap width on the refractive index4n between background and road lays is shown. The results of FDTD numerical simulation of wavelength channel splitting and the spectral analysis for the maximum efficacy of transfer energy are also presented.

A Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...

The performance of a polarizing beam splitter based on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated. The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave plates and the high-index half-wave plates with a central defect layer of air. The linear transmission properties of the polarizing beam splitter are numerically simulat...
