Abstract :
Because of dispersions in optical fibers, stable single longitudinal mode (SLM) operation is required for semiconductor lasers, which are light sources of long-haul, high capacity optical fiber communication systems. To date, phase-shifted distributed feedback laser diodes (DFB-LDs) [1] have shown the most stable SLM operation. Due to the highest stability in SLM operation, the phase-shifted DFB-LDs [1] are used in the trunk line optical fiber communication system in Japan and the fourth transpacific ocean cable system (TPC-4) between Japan and US.
