Unified Optical Modeling

Modern optical systems 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.

An efficient optical modeling requires the simulation of all of these types of components and sources with a high physical accuracy on a single software platform. LightTrans developed the concept of Field Tracing to perform these simulations. Field Tracing unifies optical modeling techniques ranging from geometrical optics to electromagnetic approaches. It enables the simulation of optical systems including diffraction, interference, partial coherence, aberrations, polarization and vectorial effects.

The VirtualLab™ package integrates several toolboxes allowing the analysis of systems, design of diffractive optical elements, design of beam shapers, analysis of gratings, analysis laser resonators as well as the shaping and homogenization of LED light.

Starter Toolbox

Unified modeling for nano, micro and macro optics

The VirtualLab™ Starter Toolbox enables you to choose from a wide range of light sources, e. g., mono- and multimode lasers, excimer lasers, LED, VCSEL and thermal sources, and propagate the emitted light through lenses, lens systems, aspherical interfaces, index-modulated components, apertures and stops, gratings and diffractive elements with features from micro meter to meter scale. [more]

Diffractive Optics Toolbox

Design of diffractive and micro optical elements

The VirtualLab™ Diffractive Optics Toolbox allows to design diffractive optical elements for laser beam splitting, light diffusing and homogenizations as well as laser beam shaping. These elements are also known as computer generated holograms, phase plates or kinoforms. Even non-experts can gain access to the world of diffractive optics with user-friendly session editors. [more]

Grating Toolbox

Rigorous analysis of 2D and 3D gratings

The VirtualLab™ Grating Toolbox allows the rigorous electromagnetic analysis of 2D gratings, 3D gratings and photonic crystals with features from nanometer to millimeter scale. Diffraction efficiency, near field, polarization and the field inside gratings can be calculated. [more]

Laser Resonator Toolbox

Flexible eigenmode analysis of laser resonators

The VirtualLab™ Laser Resonator Toolbox and Starter Toolbox together allow the analysis of stable, unstable and ring resonators including the calculation of fundamental modes, higher order modes, eigenvalues, nonlinear gain and power. Tolerance simulations enable the investigation of the stability of a resonator. [more]

Lighting Toolbox

Shaping and homogenization of LED light

The VirtualLab™ Lighting Toolbox provides field tracing for the analysis and design of illumination systems. The innovative light shaping concept which is based on arrays of gratings, prisms, and mirrors allows the shaping and homogenization of LED light. It enables a fast optimization and analysis taking into account diffraction, interference as well as spatial and temporal partially coherence. [more]
