Method of fabricating silicon waveguides with embedded active circuitry
A method of fabricating silicon waveguides with embedded active circuitry from silicon-on-insulator wafers utilizes photolithographic microfabrication techniques to define waveguide structures and embedded circuit recesses for receiving integrated circuitry. The method utilizes a double masking layer, one layer of which at least partially defines at least one waveguide and the other layer of which at least partially defines the at least one waveguide and at least one embedded circuit recess.

Advanced techniques for improving high-efficiency optical modulators
Improved optical interferometric modulators have a small waveguide spacing so that the waveguide pair are close to the central electrode, to enhance electro-optic interaction. Asymmetric waveguides with differential indices are used to effectively de-couple the waveguide pair.

Downhole optical acoustic transducers
A method of generating an acoustic signal in a subterranean well can include converting optical energy to acoustic energy downhole, thereby transmitting the acoustic signal through a downhole environment. A well system can include an optical acoustic transducer disposed in the well and coupled to an optical waveguide in the well, whereby the transducer converts optical energy transmitted via the optical waveguide to acoustic energy.
