Polarization-insensitive linear waveguide electrooptic phase modulator.

摘要

In one embodiment this invention provides a polarization-insensitive linear waveguide electrooptic phase modulator device (10). In the linear waveguide structure, the optical path has two sets of electrodes (25,26), which apply a horizontal electric field and a vertical electric field, respectively, to a nonlinear optically responsive polymeric medium in the optical path. The polymer medium section between each set of electrodes has a noncentrosymmetric molecular orientation parallel to the respective electric fields.
