ABSTRACT:
A micro-optic Mach-Zehnder interferometer with a differential delay of n bit periods, where n is an integer number, and thermal bias control is useful as a spectral filter in front of a differential detection system to accomplish a balanced receiver. The interferometer may also be arranged as a Michelson interferometer or a dual-plate interferometer.
