ABSTRACT:
Control circuits stabilize and maintain coupled-cavity lasers in a single longitudinal mode. The laser is electrically connected and mutually and optically coupled to a control means responsive to a light output signal from the laser for controlling the laser by generating a control signal to the laser to produce single longitudinal mode output. The single mode output is maintained even during high speed modulation in which the current or ambient conditions vary.
