High speed hybrid silicon evanescent Mach-Zehnder modulator and switch

Abstract
We demonstrate the first high speed silicon evanescent Mach Zehnder modulator and switch. The modulator utilizes carrier depletion within AlGaInAs quantum wells to obtain Vπ L of 2 V-mm and clear open eye at 10 Gb/s. The switch exhibits a power penalty of 0.5 dB for all ports at 10 Gb/s modulation.
