Paper Abstract

We design a micro-scale wavelength-division-demultiplexing device based on the anomalous dispersion and band gaps in photonic crystals. We first calculate the band structures needed for the analysis of the anomalous dispersion, using the finite-difference time-domain method with periodic boundary conditions. Then a simple wavelength demultiplexer is designed and simulated by use of these results. The designed demultiplexer is composed of two photonic crystal structures that have different cylinder radii and are in close contact with each other. From the computed results, the possibility of micro-scale photonic crystal demultiplexers is demonstrated.
