by Non Linear Control Strategies (NLCSTR)

SimuLase™ is the first software tool that allows a broad audience to take full advantage of the latest advances in semiconductor theory that have revolutionized device modeling over the past decade.
SimuLase™’s fully microscopic models output correct fundamental characteristics such as absorption/gain and PL-spectra and, additionally accurate carrier losses due to radiative and Auger processes.

The predictive fit-parameter-free nature of the approach offers a fundamentally improved approach to design, analysis, and optimization.

A simple, fast, and quantitatively predictive design of new devices.

A substantial reduction of required design/growth/ re-design iterations.

An unprecedented insight in the characteristics of new or existing devices.

Precise quality control using non-destructive testing.

A free demo version of SimuLase™ is available.


Easy-to-use GUI to set up heterostructures, check level positions, mode confinement, reflection, etc.

What you need

Edge-emitters, top-emitters, lasers, LEDs, V(E)CSELs, electro-absorption modulators, sensors/absorbers- if it is based on a heterostructure SimuLase is the modeling tool for it.

Various Materials

Various material choices (AIGaAsP, GaInNas, etc.)

Variable Structure Design


Easy Setup

Includes SimuLase Designer for easy set-up and variation of the structure design.

Education Discount

The educational version is available at a reduced price.

See a description of typical real life examples of how SimuLase can be used to design and analyze, e.g., edge-emitting devices and VECSELs.
