Abstract

We successfully demonstrate a monolithic integrated dual-polarization (DP) IQ modulator on thin-film lithium niobate (TFLN) platform, which consists of IQ modulators, spot-size converters (SSCs) and a polarization rotator combiner (PRC). After coupled with polarization maintaining fibers, the measured insertion loss of the modulator is 12 dB. In addition, we experimentally achieve a 1.6 Tb/s net bitrate single-carrier DP-PS-256QAM transmission.
