ABSTRACT:
Waveguides having light propagating therethrough are positioned between a common electrode and individual electrodes arranged along a charge-coupled device. The waveguides are of a type which modulate the propagating light responsive to an electric field. The charge-coupled device is activated to place charges at selected ones of the individual electrodes, creating a field across the waveguide by which light propagating through the waveguide is modulated.
