Monolithic travelling-wave Mach-Zehnder transmitter with high-swing stacked CMOS driver

View publication


We present a 20 Gb/s monolithically integrated transmitter with stacked CMOS driver and periodic-loaded PN-junction Mach-Zehnder modulator fabricated in IBM's sub-100nm technology node. Transmitter extinction ratios of 10 dB at 20 Gb/s are demonstrated.
