Abstract

Grating-coupling techniques are widely used in the silicon photonics platform. However, the alignment between fiber and chip is a significant issue to be solved. To ease alignment tolerances and simplify photonic packaging for grating-based coupling, we proposed and designed a novel waveguiding interconnect. In this paper, a 3D model of the grating-coupler device is developed and tested using BPM-Matlab and CST Studio Suite software package. Diffracted and waveguided light characteristics are studied in detail, and its coupling efficiency and mode overlapping efficiency are examined. A beneficial waveguiding and mode reshaping ability is observed, therefore validating the demonstrated design method.
