摘要
A numerical study on the design of a novel low-loss, low-cost, and low fabrication complexity, angled 3D Glass-to-SiPh coupling interface is demonstrated. The interface is composed of a 2 degrees angled 3D glass waveguide and a thin-silicon-on-insulator platform flip-chip assembled in close proximity. The overall structure is designed and optimized based on the maximization of the coupling strength (kappa) as well as the calculation of a constant loss taper (CLT) silicon taper. The reported maximum conversion efficiency is 85.7% for 1.55-mu m central wavelength and is almost flat across the entire C-band. The results were obtained using a 3D eigenmode expansion (3D-EME) propagation solver and were verified through the 3D finite-difference time-domain (3D-FDTD) simulation method.
