Abstract
We demonstrate an ultra-fast and low power all-optical gate in pump-probe configuration based on free carrier induced refractive index modulation in a 5µm radius InP/InGaAsP microdisk heterogeneously integrated onto a silicon-on-insulator waveguide circuit. High speed gating is obtained by extracting the carriers from the microdisk active layer by applying a reverse bias. Measured transient responses show that this gate is capable of working up to 20 GHz.
