Abstract

Current density Quantum dot lasers Temperature dependence Temperature distribution Temperature measurement Threshold current
We quantitatively determine the factors that decide the threshold current temperature dependence at high temperatures in state-of-the-art InP quantum dot lasers and demonstrate a design with low threshold and reduced temperature sensitivity.
