摘要

Spectral photoresponse curves, of InAs/GaAs self-assembled quantum-dot infrared photodetectors with various doping levels, were reported. Devices were illuminated through the 45° polished edge facets and data were taken with two sets of beamsplitters and windows. Polarization behaviors of transitions and effects of the number of electrons on the photoresponse spectra were demonstrated. A strong in-plane polarized, bound-to-bound transition feature was observed.
