Abstract
Fourier-transform-limited pulses (Δ τ. Δν ζ 0.35) have been obtained from a microwave-modulated DBR laser at 1.56 μm. The chirp of the gain-switched pulse is compensated for by applying a fraction of the microwave signal to the phase section, thereby creating an instantaneous frequency shift of opposite sign. The generation of short coherent pulses from such a monolithic source can be of great interest for long haul soliton transmission.Keywords
