SimuLase™ is the first software tool that allows a broad audience to take full advantage of the latest in semiconductor modelling. It's underlying fully microscopic many-body models allow to determine/predict the essential electro-optical properties like gain/absorption, refractive indicies, spontaneous emission (photo luminescence) or carrier losses due to radiative and Auger losses, with unprecedented accuracy while removing fit-parameters that used to require time and cost-intensive experimental investigations.
Tools based on the microscopically calculated properties also allow to calculate macroscopic properties like transverse and longitudinal optical modes, reflectivity and transmission spectra, surface-PL spectra that take into account cavity effects that modify the pure material PL, threshold currents or operating characteristics for V(E)CSEL structures. SimuLase also allows for easy comparisons between experimental and theoretical results. The ground breaking quality of the underlying mircoscopic many-body models has been demonstrated in dozens of articles in peer-reviewed journals (see our publications section).

You can download a real-life description of how SimuLase can be used to design, analyze and optimize e.g. edge-emitting devices and VECSELs here.

SimuLase™ provides:
the correct fundamental input that is the required starting point for any reliable device modeling. The data can be easily imported in other commercial software tools for further investigations.
an easy to use GUI-interface that allows to determine many basic characteristics of structures without any experimental feedback,
experimentally veryfied models that have lead to more than fifty publications in peer-reviewed journals over the last two decades.

And, you don't have to be an expert in microscopic manybody physics to take full advantage of this tool. SimuLase™ can preset all parameters besides the structural design automatically - taking full advantage of the fit-parameter free nature of the microscopic models. For quick shots or research interests, SimuLase allows to influence the calculation parameters or use simplified models.

You can download a free demo-version of SimuLase™ as well as its manual or a quick start guide here.
