Ultrafast modulation with subpicosecond recovery time in a GaAs/AlGaAs nonlinear directional coupler

All‐optical modulation is observed at room temperature in a GaAs/AlGaAs multiple quantum well nonlinear directional coupler using femtosecond pulses. The origin of the ultrafast (<500 fs) recovery of the device is attributed to the optical Stark effect.
