LightTrans Solutions help to minimize R&D costs and development time. Simulations with VirtualLab enable highly innovative developments of optical systems and system components. The following are the most important examples of supported Solutions:

Waveoptical Simulation and Design of Laser Systems


VirtualLab allows the optimization and design of laser systems including macro as well as micro optical components. Simulated building blocks of laser systems include a laser source, several optical components, and one or more light detectors. The simulation includes waveoptical effects like polarization, coherence, diffraction and interference. [more]


Analysis and Control of Ultrashort Pulses


VirtualLab enables the spatio-temporal simulation of fs and as pulses, including chirp, the evaluation of the optical path length, pulse deformation effects like group velocity dispersion and higher-order dispersion effects. The simulation includes waveoptical effects like polarization, coherence, diffraction and interference. [more]


Shaping, Splitting and Diffusing Light by Diffractive Optical Elements


VirtualLab enables the design and simulation of diffractive optical elements for laser light shaping. The Diffractive Optics toolbox uses the powerful Iterative Fourier Transform Algorithm and parametric optimization to optimize for example diffractive beam splitters, diffractive diffusers and diffractive and refractive beam shapers. Optical simulations include diffraction, interference, polarization and temporal and spatial degree of coherence. [more]


Homogenization and Shaping of LED and Excimer Laser Light


The optical simulation and design software VirtualLab enables the design of illumination systems for homogenization and shaping of LED and Excimer laser light. The homogenization and shaping of light can be done by micro optical elements. Optical simulation and design includes diffraction, interference, spatial and temporal degree of coherence and aberrations. [more]


Analysis and Design of Gratings


VirtualLab is a grating software which enables the rigorous simulation of 2D and 3D gratings with the Fourier Modal Method including surface gratings, volume gratings, diffraction gratings, holographic gratings, Bragg gratings, zeroth-order gratings and moth-eye structures. The analysis includes polarization effects (TE-TM or x-y coordinate system), free positioning with tilts and general incident waves. [more]


Analysis and Optimization of Laser Resonators


VirtualLab enables the simulation and optimization of fundamental and higher order resonator eigenmodes for complex stable and unstable resonator setups. The simulation includes waveoptical effects like diffraction and polarization as well as nonlinear light amplification (gain saturation), refractive index modulations (e. g. by thermal lenses) and the calculation of output power. [more]


The optical systems involved in these solutions may contain a large variety of optical components as for example refractive, diffractive, hybrid, Fresnel and GRIN lenses, diffractive optical elements, diffusers, beam shapers, diffractive beam splitters, computer generated holograms, phase plates, gratings, elements with free form surfaces and micro lens arrays. In addition light sources with different properties as for example degree of coherence, color and polarization can be used.

The optical modeling software VirtualLab enables simulations with those optical components. VirtualLab provides a variety of design algorithms for laser systems, light shaping, homogenization and illumination systems, gratings and laser resonators. The optics software VirtualLab is based on the concept of Field Tracing which unifies optical modeling techniques ranging from geometrical optics to electromagnetic approaches. Field Tracing enables the simulation of optical systems including diffraction, interference, partial coherence, aberrations, polarization and vectorial effects.
