Abstract

In this paper we describe the numerical model of a semiconductor disk laser, developed and implemented in the Photonics Group, Institute of Physics, Lodz University of Technology, Poland. It consists of four strongly interrelated components for: carrier transport, heat flow, material gain and optical phenomena calculations. Combination of these components gives the steady-state self-consistent model which enables a simulation of various aspects of a semiconductor disk laser operation. A numerical analysis of carrier and power losses within the active region of 1.3-μm GaInNAs/GaAs semiconductor disk laser has been carried out using this model.
