Crystalline grating-waveguide resonant reflectors
Crystalline grating-waveguide resonant reflectors
The demand for reliable polarised narrow-bandwidth high-power lasers has motivated the development of innovative diffractive optics that can meet such requirements. Grating-Waveguide Structures (GWS) combining a waveguide and sub-wavelength grating can be used as a polarisation-selective high-efficiency reflector.
However, the maximum power (fluence) that can be used with these optics is limited by the intrinsic absorption and damage threshold of the compound materials. In this work, we report on the first resonant reflectors based on GWS made entirely of crystalline materials, which potentially offer better thermal and mechanical properties. Such crystalline GWS devices could enable operation at higher powers than conventional materials currently allow.

Abstract
The demand for reliable polarised narrow-bandwidth high-power lasers has motivated the development of innovative diffractive optics that can meet such requirements. Grating-Waveguide Structures (GWS) combining a waveguide and sub-wavelength grating can be used as a polarisation-selective high-efficiency reflector.
However, the maximum power (fluence) that can be used with these optics is limited by the intrinsic absorption and damage threshold of the compound materials. In this work, we report on the first resonant reflectors based on GWS made entirely of crystalline materials, which potentially offer better thermal and mechanical properties. Such crystalline GWS devices could enable operation at higher powers than conventional materials currently allow.
