Ultralow-loss silicon waveguide crossing using Bloch modes in index-engineered cascaded multimode-interference couplers

Ultralow-loss silicon waveguide crossing using Bloch modes in index-engineered cascaded multimode-interference couplers

We investigate the loss mechanism in three-moded multimode-interference couplers that are the building blocks of a compact and low-loss waveguide crossing structure. Broadband silicon waveguide crossing arrays with
