Title: Ultra-low loss hollow core waveguide using high-contrast gratings
Usefulness: Ultra-low loss hollow core waveguide using high-contrast gratings
Summary: Apparatus for guiding light propagated through high contrast grating-hollow waveguides (HCG-HW) for compact optical delay line, advanced optical filters, true time delay phased array antennas, data packet traffic engineering, interferometric sensors and on-chip optical communication.
Novelty: Apparatus for guiding light propagated through high contrast grating-hollow waveguides (HCG-HW), has core that receives incident light beam between gratings and provides lateral confinement in response to glancing reflections
