Abstract

Gain-coupled distributed-feedback (GC-DFB) lasers have been proposed and demonstrated by using a corrugated active1,2 or absorptive3-5 layer to modulate the modal gain along the cavity length such that a single-longitudinal-mode oscillation is generated. The GC-DFB lasers show excellent static characteristics, such as high single-mode yield2,3 and a high side-mode suppression ratio.2,4 Ultralow-chirping short-pulse generation in the 0.88-µm wavelength region1,5 is the only dynamic characteristic reported so far to the best of our knowledge. In this work we have studied the dynamic characteristics of 1.5-µm compressive- strained multiple-quantum-well (CS-MQW) GC-DFB lasers by fabricating such lasers on semi-insulating InP substrates to avoid the parasitic capacitance that causes the high-frequency roll-off.
