Abstract

By the combination of multimode interference and photonic crystals, a broad-band 1.3/1.55-µm demultiplexer can be realized with very compact structure. Simulation with the finite-difference time domain method verifies its excellent performance, greater than 20dB isolation ratio and less than 3 dB insertion loss over 100nm bandwidth at both wavelength bands.
