Abstract
This article presents a 100-Gb/s four-level
pulse-amplitude modulation (PAM4) optical transmitter
system implemented in a 3-D-integrated silicon photonics-
CMOS platform. The photonics chip includes a push–pull
segmented Mach–Zehnder modulator (MZM) structure using
highly capacitive (415 fF–1.1 pF), yet optically efficient
(V
π L = 0.8V ·cm) metal–oxide–silicon capacitor (MOSCAP)
phase modulators. Two pairs of U-shaped modulator segments
with effective lengths of 170 and 450 μm are driven at 50 G
