Picosecond (< 2.5 ps) wavelength-tunable (~20 nm) semiconductor laser pulses with repetition rates up to 12 GHz

Abstract

A novel technique is used to produce picosecond wavelengthtunable optical pulses from gain-switched Fabry–Perot semiconductor lasers using fibre compression. Experiments are carried out with high power, large modulation-bandwidth lasers at 1.3 μm. Pulses of 2.5 ps durations with repetition rates up to 12 GHz are obtained. Still shorter pulses (~1 ps) with higher repetition rates (18 GHz) are shown to be feasible.
