Chalcogenide glass waveguides for refractive non-mechanical beam steerer

A method for making a chalcogenide glass waveguide in a liquid crystal-based non-mechanical beam steering device that permits steering in the mid-wave infrared. The waveguide core, the subcladding, or both comprise a chalcogenide glass. A mask is used to produce a tapered subcladding. Also disclosed...

Zusammenfassung:	A method for making a chalcogenide glass waveguide in a liquid crystal-based non-mechanical beam steering device that permits steering in the mid-wave infrared. The waveguide core, the subcladding, or both comprise a chalcogenide glass. A mask is used to produce a tapered subcladding. Also disclosed is the related non-mechanical beam steering device that includes a chalcogenide waveguide.
