We report on optically induced charge transport measurements through conducting submicron channels in AlGaAs/GaAs heterostructures. The channels are defined within a two-dimensional electron gas in a quantum well by chemical etching. By applying a voltage to a top gate, the channels can be depleted electrostatically. We present two different heterostructure designs and two processing techniques ...
