Abstract: Electro-optical devices and methods for constructing electro-optical devices such as a switch or phase shifter. An electrode layer is deposited on a substrate layer, a waveguide structure is deposited on the electrode layer, a first cladding layer is deposited on the waveguide structure, and the first cladding layer is planarized and bonded to a wafer. The substrate layer is removed and the electrode layer is etched to split the electrode layer into a first electrode separated from a second electrode. A second cladding layer is deposited on the etched electrode layer. The first and second electrodes may be composed of a material with a large dielectric constant, or they may be composed of a material with a large electron mobility. The device may exhibit a sandwich waveguide architecture where an electro-optic layer is disposed between two strip waveguides.

Abstract: Photonic devices are disclosed including a first cladding layer, a first electrical contact comprising a first lead coupled to a first dielectric portion, a second electrical contact comprising a second lead coupled to a second dielectric portion, a waveguide structure comprising a slab layer comprising a first material, and a second cladding layer. The slab layer may be coupled to the first dielectric portion of the first electrical contact and the second dielectric portion of the second electrical contact. The first dielectric portion and the second dielectric portion may have a dielectric constant greater than a dielectric constant of the first material.

Abstract: An optical device includes a first waveguide that includes a plurality of first portions coupled with regions doped with first dopants, and a plurality of second portions coupled with regions doped with second dopants, distinct from the first dopants, the plurality of first portions being interleaved with the plurality of second portions. And the optical device includes a second waveguide located adjacent to the first waveguide for coupling light from the first waveguide to the second waveguide. The second waveguide includes a third portion coupled with a third region doped with the first dopants and a fourth portion coupled with a fourth region doped with the second dopants, wherein the first portion is located adjacent to the third portion and the second portion is located adjacent to the fourth portion.
