Monolithically integrated CMOS nanophotonic segmented Mach Zehnder transmitter

We present a monolithic segmented Mach-Zehnder transmitter, fully integrated in a 90 nm CMOS process. The transmitter exhibits a link sensitivity of -14.1 dBm optical modulation amplitude (OMA) at bit error rate (BER) = 10−12 at 12.5 Gbps.
