Photonic Crystal Based Arrayed Waveguide Grating Demultiplexer for Optical Network

A powerful aspect of the optical communication link is that, multiple wavelengths can be sent along a single fiber simultaneously in the 1300 to 1600nm spectral band. A novel design of Arrayed Waveguide Grating (AWG) de-multiplexer on 2D photonic crystal is proposed. This device offers 200GHz channel separation and -32dB theoretical cross talk. Finite Difference Time Domain method (FDTD) is used for evaluating the device at 1550nm.The performance of the device is evaluated in terms of device length, optical efficiency and channel spacing. The novel device presented here can be used as Optical Cross Connect (OCC), True Time Delay line (TTD) and multiplexer.
