Abstract
A liquid crystal-based non-mechanical beam steering device that permits steering in the mid-wave infrared and has a chalcogenide waveguide. The waveguide core, the subcladding, or both comprise a chalcogenide glass. The liquid crystal-based non-mechanical beam steering device has a tapered subcladding and a liquid crystal layer.
Claims5
A non-mechanical beam steering device, comprising:
- a substrate, wherein the substrate serves as a bottom electrode;
- a tapered subcladding deposited on the substrate, wherein the tapered subcladding comprises a germinate glass or a fluoride glass;
- a waveguide core deposited on the tapered subcladding, wherein the waveguide core has a higher refractive index than the tapered subcladding, and wherein the waveguide comprises a chalcogenide glass;
- a liquid crystal layer on the waveguide;
- and
- a glass plate patterned with top electrodes on the liquid crystal layer.
