Abstract :
We have fabricated a compact 224-Gb/s dual-polarization 16-ary quadrature amplitude modulation (DP-16QAM) modulator module consisting of InP-based Mach-Zehnder modulators (MZMs), linear driver ICs and polarization multiplexing micro-optics. We have demonstrated a very low power dissipation of 3.2 W with comparable performance to LiNbO3-based modulator in back-to-back operation.
