| Abstract(in English) | We demonstrate a compact all-optical Michelson interferometer (MI) gating switch with monolithic integration of two different band gap energies. Based on the ion-induced intermixing in In GaAs/AlAsSb coupled double quantum wells, the blue shift of the band edge can be tailored. Through phosphorus ion implantation and subsequent annealing, an implanted sample can acquire a high transmittance compared with the as-grown one. Meanwhile, the cross phase modulation (XPM) efficiency of a non-implanted sample undergoing the same annealing process decreases little. An implanted part for signal propagation and a non-implanted section for XPM are thus monolithically integrated for an MI switch by an area-selective manner. Full switching of a π-rad nonlinear phase shift is achieved with pump pulse energy of 5.6 pJ. |
