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 ...

Abstract: Two-dimensional (2D) sampling structures based on tilted Bragg grating (TBG) for distributed feedback (DFB) laser are proposed and demonstrated. The phase-matching condition of the 2D ...
