How to simulate a semiconductor quantum dot laser: general description

Abstract

Semiconductor quantum dot laser is a recent class of laser sources which is an alternative to the conventional bulk and quantum well lasers. In the development of laser sources an important step concerns the modeling of the devices to be realized, and this requires the use of good methods able to incorporate various physical phenomena present in real devices. In this paper we show in details the implementation of a quantum dot laser simulator and apply it to simulate the switching-on behavior and other characteristics of a real quantum dot laser source. The description here presented intends to be a help for teaching or even basic-research in that particular field of optoelectronics.
