Abstract

Abstract In this paper, an all-optical 1 × 4 demultiplexer (DEMUX) has been designed by employing 2D photonic crystal (PhC) waveguides for use in optical networking and signal processing. The proposed structures consist of four T-shaped and one Y-shaped waveguide using 15a × 15a rectangular lattice silicon rods in ambient air. All-optical DEMUX has been simulated using the finite-difference-time-domain (FDTD) method and the results have been verified by distributing the optical field at a wavelength of 1.90 μm. Analysis of the device has been carried out for distinctive crystal and lattice designs with the achievement of a transmission ratio of more than 2.05 in presence of select input.
