Abstract:
1. 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 said core is constructed of electro-optic material(s), wherein said waveguide includes a modulating region and a non-modulating region, wherein said layers of cladding materials having lower indices of refraction than said core for guided mode, wherein said layer of cladding material having higher indices of refraction than said core for non-guided mode; two ports coupled to each end of said waveguide; a light that propagates into said waveguide; a substrate dimensioned and configured to integrate a plurality of optical components, wherein said optical components include a waveguide and said ports; and a waveguide configuration including said waveguide, wherein each said end of waveguide is coupled to said port for one-way propagation of said light.
