Abstract
Gain-switching a strained-layer multiple quantum well laser-amplifier photonic integrated circuit has produced optical pulses with durations of 28 ps and peak powers of 590 mW (i.e. pulse energies of 21 pJ). The device was gain-switched at frequencies from 2 to 8 GHz. Such monolithic high-power pulse sources are of great importance for nonlinear fibre device applications.
