Abstract
The carrier-induced frequency modulation (FM) mechanism is investigate d for tunable three-electrode DFB lasers. The bias current dependence of the FM efficiency in actual devices is successfully explained in a concise manner. The direction of the frequency shift (blue or red shif t) depends on the position of the lasing mode in the stopband, which i s determined by both the carrier and the thermal effects on the refrac tive index under a given bias condition.
