Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail ...
Abstract: We propose and validate a new approach for low-back-reflection and high-efficiency silicon waveguide grating couplers (GC) with a fully etched structure. Enhanced coupling efficiency is ...
