Description
Summary:Despite that non-linear mode operation of GaAs photoconductive semiconductor switches (PCSSs) has a noble high gain photoelectric behavior, it suffer from electrode degradation as well as its destruction at high current driving. Several ways to avoid current concentration have been suggested by some frontiers, but those still require additional photonic devices or complex semiconductor processing 1 . In this paper, we will show a simple, low cost way to create periodic-trench structures (PTSs) for isolating each current path by using a usual wafer sawing machines.
