Abstract

Method and apparatus for deflecting and modulating a beam of coherent radiation wherein an electric potential is applied across the electrodes of an MOS semiconductor device to vary the thickness and hence conductivity of the depletion layer therein. Incident radiation being propagated through the semiconductor, or alternatively through the depletion layer itself, is deflected and/or modulated as the thickness of the depletion layer is varied.
