ABSTRACT:
A broadband microwave waveguide modulator uses microwave signal frequencies to provide phase modulation of an infrared laser propagating in a guided mode through a common electrooptic interaction region in the form of a microstrip transmission line, provided by electroplating microwave electrodes on each of two mutually opposed major surfaces of a monolithic, thin-film optical waveguide having uniform thickness, to provide a high efficiency conversion of a portion of the laser carrier power into optical sideband signals.
