Abstract

A semiconductor laser with a strongly asymmetric waveguide structure and a relatively thick (similar to 0.1 mu m) active layer, resulting in an extremely large equivalent spot size, is proposed and analyzed for the purpose of generating high-power single-optical pulses by gain switching. An improvement in obtainable single-pulse energies of about an order of magnitude over conventional laser structures is predicted.
