Calculated Optimum Parameters for Nonuniform Grating Couplers of Silicon Waveguides with an Aluminum Backside Mirror Coating

초록

In this paper, we present numerically calculated optimum parameters of nonuniform Bragg grating couplers on silicon waveguides (SWs) for fiber coupling with an Al mirror coating on the bottom side of the conventional silicon-on-insulator (SOI) wafers.
