英文摘要
We fabricated GaAa/ AlAs multilayer cavity structures with InAs quantum dots(QDs) embedded in strain-relaxed InGaAs layers by molecular beam epitaxy on the GaAs substrate, and nonlinear optical responses were investigated. We found that Er-doping induced ultrafast decay of the photo-excited carriers in the InAs QDs, and confirmed that nonlinear optical signals with a response time of around 1ps were obtained in the cavity structure with QDs, which were two order of magnitude larger than that without QDs.
