| titleOfInvention | Waveguides and devices incorporating optically functional cladding regions |
| abstract | Waveguides and integrated optical devices incorporating optically functional cladding regions are provided. In accordance with one embodiment of the present invention, an electrooptic clad waveguide (10) is provided with an optical waveguide core (20) and first (22) and second (24) electrooptic cladding regions. The optical waveguide core is a substantially non-electrooptic material. The cladding regions are electrooptic polymers defining a refractive index that is less than that of the core. The first and second cladding regions may be poled in opposite or perpendicular directions or along a contour of an electric field. Additional embodiments of the present invention utilize other types of optically functional materials in the cladding regions. Integrated optical devices according to the present invention comprise phase modulators, intensity modulators, 2x2 polarization independent optical switches, high-frequency modulators, wavelength-dependent optical switches, directional couplers employing electrooptic gaps and electrooptic cladding regions, and optical devices with thinned-down waveguide channels and phase compensating elements. |
