A four-channel integrated 1.55 ..mu..m multielectrode distributed-feedback (DFB) laser array was fabricated using the MOVPE/LPE hybrid method. Simultaneous single-longitudinal mode operation was achieved in each multielectrode DFB laser on a single chip. Utilizing the frequency tunability of multielectrode DFB lasers, optical frequency spacings were controlled and set to within a few gigahertz. The drift of frequency spacings due to temperature fluctuation was in the range of +-50 MHz for a temperature control of +-0.1/sup 0/.
