Abstract
A periodic multi/demultiplexer that has a square spectrum response with a 2 00-GHz free spectrum range was fabricated using a modified Mach-Zehnder int erferometer with MMI couplers, a delay line, and a ring resonator. A large enhancement of the FSR is obtained by using a deep ridge waveguide, The tra nsmission bandwidths of 1 dB down and -15-dB rejection are about 75 GHz and over 50 GHz, respectively.
