Simulation and Qualitative Analysis of a Single Mode Semiconductor Laser Model

Abstract

In this paper the dynamics of a single-mode semiconductor laser model is investigated. The nonlinear rate equations describe the dynamic evolution of semiconductor laser. We study transients occurring in the system using numerical simulation. A fourth order Runge-Kutta method is used to calculate two coupled first-order differential equations. Changes in the pumping parameter of the system can lead to drastic changes of the character of the solutions. Qualitative analysis of the system is used for investigating the typical bifurcations and allowed conditions for the existence of damped oscillations in the system.

Design of a Low Threshold Single-Mode In-P Laser Using Regrowth-Free Fabrication

“…τ 𝑝 𝑖 can be calculated by using Equation (10). The value of α ℎ = 2 is used in the simulation as in [41]. Only five modes are considered in the simulation to study the static behaviour such as L-I, threshold and SMSR of the laser.…”
