Abstract: The self-assembled InGaAs/GaAs quantum dots superlattices for 8 ~ 12pm infrared photodetector working at atmospheric window are grown by MBE. It is demonstrated that the intersublevel absorption wavelength of InGaAs/GaAs quantum dot superlattices can be ad usted by varying the shape and size of quantum dots and the thickness of InGaAs layer. It is observed that as the thickness of InGaAs layer increased the infrared absorption peak blue-shifts from 15 to 10pm. The changes can be attributed to the enhanced effect of coupling between quantum dots.
