STABILIZING OPTICAL SOURCES IN A COMMUNICATION SYSTEM

摘要

An optical device operative to stabilize an output of at least one optical source at a predefined wavelength. The devices comprises: at least one optical source, a calibrated reference source, an optical heterodyne receiver which is operative to detect a wavelength difference between the reference source and each of the at least one optical source, and means for adjusting the wavelength of each of the at least one optical source according to the wavelength difference.
