Fabrication-tolerant, 2-mode, 4λ multiplexer based on Si waveguides for beyond Tbit/s optical Ethernet

Abstract

A fabrication-tolerant, 2-mode, 4λ multiplexer is proposed for beyond Tbit/s optical Ethernet system. Various techniques for strengthening fabrication tolerance are introduced, and a proof-of-concept device is fabricated for Si-photonics platform.
