ABSTRACT:
A spatial light modulator includes a multiple quantum well (MQW) device. Unlike MQWs of the prior art, this MQW is made semi-insulating. As a result, individual picture elements can be defined entirely by the placement of electrodes in an array on a surface of the device. Them is no need to etch trenches for electrical isolation of the picture elements.
