Filter-embedded wavelength-division multiplexerfor hybrid-integrated transceiver based on silica-based PLC

Abstract

A thin film filter-embedded wavelength-division multiplexer is designed for a hybrid-integrated WDM transceiver based on a silica-based PLC platform. A compact multiplexer with a low insertion loss of 1.1 dB and a low crosstalk of <–50 dB is successfully fabricated.
