Paper Abstract

A numerical study on the design of a novel dual polarization, low loss, and low fabrication complexity, angled 3D Glassto- SiPh coupling interface is presented. The interface is composed of a 2° angled 3D glass waveguide attached to a thin-SOI platform. The coupler design and the optimization methodology relies on the optimum Constant Loss Taper (CLT) silicon taper calculation. The achieved coupling efficiency is 83.50% and 81.22% for TE and TM polarization state, respectively, at 1.55 μm. The results are obtained using an EigenMode Expansion (EME) propagation solver and are verified through the 3D FDTD simulation method.
