ABSTRACT:
An optical phase modulator comprising a plurality of polarizing waveguides having a layered stack including a core between at least one layer of cladding material, wherein the core is constructed of electro-optic material(s), wherein the layers of cladding materials having lower indices of refraction than the core for guided mode, wherein the layers of cladding materials having higher indices of refraction than the core for non-guided mode, at least one electrode coupled to at least one waveguide including a modulating polarizing region, at least one waveguide having a non-modulating region and a modulating region, a substrate dimensioned and configured to integrate a plurality of optical components, wherein the optical components include a plurality of polarizing waveguide(s), a waveguide having a non-modulating region and a modulating region, coupler/splitter(s), electrode(s), and a waveguide configuration including a first polarizing waveguide, a second polarizing waveguide and a third polarizing waveguide.
