64QAM Modulator with a Hybrid Configuration of Silica PLCs and LiNbO_3 Phase Modulators for 100-Gb/s Applications

摘要

We demonstrate an optical 64QAM modulator operating at 60 Gb/s (with single polarization). Asymmetric couplers and an array of 12 high-speed phase modulators are integrated with a hybrid configuration of silica PLCs and LiNbO_3 phase modulators.
