Abstract
This article presents an electro-absorption modula-
tor (EAM)-based single-mode (SM) 50-Gb/s non return to zero
(NRZ) Si-photonic optical link in a 16-nm FinFET. The EAM
device is modeled to include its electrical and optical properties.
The transmitter (TX) uses T-coil based over-peaking to improve
modulation efficiency and relax transimpedance amplifier’s
(TIA’s) bandwidth and noise requirement. The receiver (RX) uses
a three-stage TIA with T-coils to improve bandwidth. The link
sensitivity is −
