Femtosecond Switching Speed in a Current-Injected GaAs/AlGaAs Multiple Quantum-Well Nonlinear Directional Coupler

We have demonstrated ultrafast switching behavior in a current-injected GaAs/AlGaAs multiple quantum well nonlinear directional coupler at room temperature. The results show low cross-over pulse energy (6 pJ) and full recovery within 1 picosecond.
