摘要：

A coupled double quantum well (C-DQW) structure enabling ultrafast, multiwavelength, all-optical modulation using intersubband transitions is proposed. It has been demonstrated by calculating the absorption and relaxation characteristics that the InGaAs/AlAsSb C-DQW structure is desirable for application in all-optical switches for multiwavelength operation at near-infrared wavelengths down to 1.3 mu m. The capability of ultrafast all-optical switching/wavelength conversion between 1.3 and 1.55 mu m has also been demonstrated.
