High speed travelling wave carrier depletion silicon Mach-Zehnder modulator

DeRose, Christopher T.; Trotter, Douglas C.; Zortman, William A.; Watts, Michael R.

We present the first demonstration of a travelling wave carrier depletion Mach-Zehnder modulator impedance matched to 50 . This device has a bandwidth of 24 GHz and a halfwave voltage length product of 0.7 V-cm, placing it among the best in its class. © 2012 IEEE.
