BALaser for the simulation of dynamics in broad-area semiconductor lasers


This software is used for simulations of the nonlinear dynamics in high-power edge-emitting (B)road-(A)rea semiconductor (Laser)s. It integrates numerically the dynamic traveling wave model defined in two spatial dimensions. When needed, it allows accounting for inhomogeneous current-spreading and heat-flow defined in all three spatial dimensions. It also executes different data post-processing routines and visualizes the obtained data.


ddfermi - drift diffusion simulation tool


ddfermi is a software prototype which simulates drift diffusion processes in classical and organic semiconductors. It uses a finite volume discretization of the basic semiconductor equations as well as thermodynamically consistent, state-of-the-art flux approximations.


LDSL-tool for the simulation of longitudinal dynamics in semiconductor lasers


This software is used to investigate and design multi-section lasers, lasers with optical feedback, and coupled laser devices that exhibit various nonlinear dynamical effects such as pulsations, chaos, hysteresis, optical mode switching, excitability, mutual synchronization, and frequency locking by an external modulated optical or electrical signal.
