Abstract
An integrated-optic, polarization-selective phase modulator is disclosed. a preferred embodiment of the invention a channel waveguide provides a path therethrough for polarized light having horizontal and vertical polarization components, and an electrode structure is disposed above the channel waveguide and is responsive to the application of a control voltage to the electrode structure for substantially phase modulating only the vertical component of the polarized light.
Claims9
An integrated-optic, polarization-selective phase modulator comprising:
- a unitary substrate;
- a channel waveguide extending longitudinally along said unitary substrate for providing a path therethrough for polarized light having first and second polarization components;
- and
- first and second configurations of electrodes respectively disposed in proximity to first and second portions of said channel waveguide;
- said first and second configurations of electrodes being responsive to the applications of a control voltage to each of said first and second configurations for operating on each of said first and second polarization components differently so that substantially only one of the first and second polarization components of the polarized light is phase modulated by the application of said control voltage thereto.
An integrated-optic, polarization-selective phase modulator comprising:
- a unitary substrate;
- a channel waveguide formed in said unitary substrate for providing a path therethrough for polarized light having horizontal and vertical polarization components;
- and
- an electrode structure disposed above said channel waveguide and being responsive to the application of a control voltage to said electrode structure for operating on each of said horizontal and vertical polarization components differently in order to substantially phase modulate only the vertical polarization component of said polarized light.
