Abstract
An optical phase modulator comprising a plurality of non-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 layer of cladding material having higher indices of refraction than the core for non-guided mode, a substrate dimensioned and configured to integrate a plurality of optical components, wherein the optical components include a plurality of non-polarizing waveguide(s), a waveguide having a non-polarizing non-modulating region and a non-polarizing modulating region, coupler/splitter(s), electrode(s), a waveguide configuration including a first non-polarizing waveguide, a second polarizing waveguide and a third waveguide, and at least two optical fiber pigtails where one is coupled to a second and third waveguide.
