Abstract

An optical dual-carrier generator, four parallel IQ modulators, and a polarization multiplexer are integrated in a single modulator with a silica-LiNbO₃ hybrid configuration. By driving the modulator with high-speed DACs we developed, we generated a 400-Gb/s dual-carrier dual-polarization 16QAM signal.
