Abstract

The electroluminescence of a quantum-dot (QD) laser diode was found to blueshift as the injection current is increased. The carrier distribution within the QD layers was modeled and the Stark shift, measured from photocurrent, was used to explain the large blueshift seen in the electroluminescence. The built-in electric dipole was found to be dependant on growth conditions.
