High speed silicon optical modulators must be compatible with CMOS drivers to reach their full potential for low cost and low power consumption. We designed a CMOS driver for a Mach-Zehnder modulator (MZM) that has been segmented to lower required voltage swings on a per segment basis and to increase the speed. Previous inductor-less drivers produced on the same process, IBM 130 nm CMOS, ran at 10...
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.
