Novel Design of Four-Channel Wavelength Division Demultiplexer Based on Two-Dimensional Photonic Crystal Ring Resonators

EasyChair Preprint 9061

Abstract

In this study we investigated four-channel optical demultiplexer using two dimensional photonic crystal ring resonators with a square lattice structure. The numerical simulation results show that the output transmission efficiency and the quality factor are 99.45%, and 1613, respectively. The crosstalk between -11.16 dB and -33.93 dB was attained. The finite difference time domain and plane wave expansion methods were chosen to demonstrate the performance of the considered device. The total size of the structure, is about 269 µm² which is suitable for optical integrated circuits (PICs) and appropriate for WDM (wavelength division multiplexing) technologies.

Keyphrases: Crosstalk, Demultiplexer, FDTD, Quality factor, photonic crystal
