Design of Silicon Photonics Based Enhanced Evanescent Coupling Mode-Division Multiplexer and De-multiplexer for Footprint Reduction

Abstract

A design of silicon-photonics (SiPh) based 4 x 4 enhanced-evanescent-coupling mode-division-multiplexing (EEC-MDM) multiplexer/de-multiplexer is proposed. Compared with the traditional MDM, our proposed EEC-MDM can significantly reduce the footprint while archiving similar coupling efficiencies.
