ABSTRACT:
An optical phase modulator comprising a polarizing waveguide having two ends and 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 waveguide includes a modulating region and a non-modulating region, wherein the layers of cladding materials having lower indices of refraction than the core for guided mode, wherein the layer of cladding material having higher indices of refraction than the core for non-guided mode, two ports coupled to each end of the waveguide, a light that propagates into the waveguide, a substrate dimensioned and configured to integrate a plurality of optical components, wherein the optical components include a waveguide and ports, and a waveguide configuration including the waveguide, wherein each end of waveguide is coupled to a port for one-way propagation of the light.
