ABSTRACT:
An opto-electronic device, comprising an optical waveguide and means for imposing an electrical field in a direction transverse to the waveguide, is designed such that the spatial spread of the electrical field is very small. The electrical field overlies the region of peak amplitude of the profile of optical radiation in the waveguide. Constructed principally out of semiconductor materials made from elements selected from the III and V groups of the Periodic Table, the device lends itself to monolithic integration in optical communications systems.
