Numerical investigation of hybrid taper–grating coupling for broadband fiber-to-chip interfaces in silicon photonics

Abstract One of the most critical bottlenecks in photonic integrated circuit packaging in today’s scenario is efficient optical coupling between single-mode fibers (SMFs) and silicon-on-insulator (SOI) photonic chips. This is due to the severe mode-field diameter mismatch, which...
