Performance Enhancement of Cavity Assisted Photonic Crystal De-Multiplexerin Slow Light Regime

Abstract

This study first proposes a new version of a photonic crystal based de-multiplexer operating under the slow light regime, secondly analyses the structure numerically to demonstrate de-multiplexing operation and finally studies the impact of light speed on the performance of the proposed structure. The operation wavelength is 1.55 µm. The study indicates that, by adjusting the speed of light, around 0.1C, in the main waveguide and in the output channels' waveguides, an enhancement in the performance of the de-multiplexer will be gained.
