A monolithic 56 Gb/s CMOS integrated nanophotonic PAM-4 transmitter
Abstract
We report a demonstration of four-level pulse amplitude modulation (PAM-4) using a segmented traveling-wave silicon photonic Mach-Zehnder modulator with monolithically integrated CMOS drivers. The PAM-4 transmitter shows clear eye openings up to 28 Gbaud.
