Wavelength division multiplexer based on photonic crystal filters integrated into silicon-on-insulator waveguides

Abstract

A photonic crystal (PC)-based FP filter in silicon-on-insulator (SOI) is designed and simulated by finite-difference time-domain (FDTD) approach. The result is compared to a fabricated PC filter. A wavelength division multiplexer (WDM) component occupying only 500 ¿m2 based on this filter is designed and simulated.
