Abstract :
A new method to manipulate the chirp characteristics of laser-diode pulses is proposed, utilising the cross-phase modulation in optical fibres. Chirping manipulation of a red-shift chirped pulse from a 1.3 mu m gain-switched distributed-feedback laser diode is first demonstrated by compensating for the residual chirp through the blue-shift chirp induced by a 1.3 mu m intense YAG pump pulse.
