Abstract

We present the analysis of threshold conditions that produces wideband- stimulated emission in semiconductor quantum-dot laser. Our theoretical model reveals critical occurrence of broadband lasing when the energy spacing between quantized energy states (ΔE) is comparable to the inhomogeneous broadening of quantum dot nanostructures.
