ARRAYED WAVELENGTH GRATING ROUTER (AWGR) FOR WAVELENGTH MULTIPLEXING AND DEMULTIPLEXING

摘要

An Arrayed Waveguide Grating Router (AWGR) for wavelength multiplexing and demultiplexing is provided. According to an aspect, by generating phase differences of a plurality of received optical signals through an arrayed wavelength in which a plurality of waveguides having a predetermined length difference with respect to each other are arranged, and then coupling the optical signals with the different phase differences, wavelength multiplexing and wavelength demultiplexing are simultaneously performed using the maximum constructive interference and/or destructive interference effect of optical signals.
