摘要：
Semiconductor lasers with a flat FM response are required for coherent FSK transmission systems. A complex-coupled lambda/4-shifted DFB laser is described that gives a flat FM response from 10kHz to 17GHz at 15mW, achieved by using the self-suppressing mechanism of the spatial hole-burning effect.
