Abstract
This article focuses on optical connectivity and coupling efficiency to and in between waveguides. We present numerical simulation results of our proposed multitaper (MT) high efficiency coupler that indicates low coupling losses and robustness to misalignment coupling errors. We obtained an absolute coupling loss of 0.85-dB coupling into a silicon waveguide and an improvement of 19 dB in vertical misalignment and 13 dB in angular misalignment, compared with existing coupling techniques. We conclude that using the MT, high efficiency coupling can be achieved while the dimensions and geometry can be adjusted and optimized for the specific configuration.
