Abstract

Engineering Engineering, Electrical & Electronic Optics Physical Sciences Physics Quantum Science & Technology Science & Technology Technology
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 (Delta E) is comparable to the inhomogeneous broadening of quantum dot nanostructures.
