Various electrical and optical schemes used in Mach-Zehnder (MZ) silicon plasma dispersion effect modulators are explored. A rib waveguide reverse biased silicon diode modulator is designed, tested and found to operate at speeds up to 13 GHz with a V"L of 1. Here VM is the differential voltage applied between the two input ports and V is the voltage necessary for phase shift, also called the switching voltage. = and the chirp is ideally zero. =, then we get a purely phase modulated signal and. Abstract—Linearity of Si Mach-Zehnder Modulators (MZM) is characterized with a newly-proposed modeling technique which includes the influences of the transmission characteristics of traveling-wave (TW) electrodes and the electro-optic (EO) char- acteristics of PN junction phase shifters within Si. In this paper, we review our progress on carrier-depletion-based silicon modulator. Silicon Photonics modulators in the configuration of a Mach–Zehnder interferometer, in which a PN-junction rib-waveguide phase shifter is inserted in each arm.
