Paper Abstract

A channel spacing frequency stabilization system for optical frequency-division-multiplexing communications is reported. Considering variable environmental condition and device aging effects, we have designed two loops in the system using a Fabry-perot interferometer as a frequency reference. One loop is a fine-tuning one, which is a time-division-multiplexing frequency stabilization scheme adjusting the driving currents of all the transmitter. The other loop is a rough-tuning one, which is a series of newly designed digital temperature controllers in which microprocessors and electrical oscillation circuits rather than Wheatstone bridge- circuits are used to detect the temperature error signal in order to reduce laser operating temperature dependence on the environmental conditions and there are RS-232 interfaces for communications with the first loop.
