Abstract :
In this paper, an InGaAsP/InGaAlAs high-band-offset quantum well for high-speed all-optical wavelength conversion is reviewed. Due to large band offset ratio between electron and heavy hole, InGaAsP/InGaAlAs multiple quantum well can have short carrier sweeping time under electric field from low hole band offset. Large than 33GHz of all-optical frequency response is demonstrated under high bias, confirming such material can be used for high speed all optical network.
