Unified modeling for nano, micro and macro optics

Interferogram of a polychromatic spherical wave and a vortex wave.

The VirtualLab Starter Toolbox enables the simulation of laser optics, micro optical systems, diffractive optics, interferometers, imaging and illumination systems. Optical systems may contain refractive, diffractive, hybrid, Fresnel and GRIN lenses, diffractive optical elements, diffusers, beam shapers, diffractive beam splitters, computer generated holograms, phase plates, elements with free form surfaces and micro lens arrays. Based on unified optical modeling, the light propagation can be modeled using different propagation models ranging from geometrical optics to physical optics.

VirtualLab provides parametric optimization for optical systems, e.g. laser systems. Diffraction, interference, polarization effects and aberrations can be taken into account during the optimization.

VirtualLab's unique customization features enable the simulation of user defined surface profiles, light sources, transmissions, index modulated media and components just by entering a formula. In addition users can add arbitrary merit functions and field evaluations. Various import filters allow to import surface and laser data from other software and measurement devices.

Selected Features

Y-component of the electrical field in the focal region of a lens with a numerical aperture of 0.68.

Simulation of high NA laser and imaging systems. The Starter Toolbox enables the investigation of paraxial and non-paraxial laser and imaging systems including diffraction effects, interference effects, aberrations, polarization and vectorial effects. Lens data can be imported from Zemax. Programmable interface, light source, transmission, material, medium and programmable component allow to customize optical components. The toolbox allows for example the evaluation of the fiber coupling efficiency, beam parameters, PSF, MTF and power density in focal regions.

Simulation of micro and diffractive optical components. You can analyze the optical effects of diffractive, hybrid, Fresnel and GRIN lenses, diffractive optical elements, diffusers, beam shapers, diffractive beam splitters, computer generated holograms, phase plates and micro lens arrays. Simulations of light propagation include diffraction, interference, stray light, efficiency, uniformity, signal-to-noise ratio (SNR) and zero order intensity. Measured data of micro structured height profiles can be imported  from ASCII and bitmap files into VirtualLab.

Modeling of ultrashort pulses. VirtualLab enables the modeling and propagation of ultrashort pulses through laser systems. The propagation includes diffraction effects, interference effects,  aberrations, polarization and vectorial effects. The pulse shape can be visualized depending on the lateral laser beam position.

Simulation of temporal and spatial partially coherent light. Several real light sources, as for example, LED’s, Excimer lasers, multimode lasers, thermal sources generate temporal and spatial partially coherent light. The coherence properties of real light distributions can be included in simulations.  This is important especially for optical systems whose optical functions are based on diffraction and interference effects.

Parametric optimization and parameter run. The parametric optimization allows to optimize a great variety of optical systems e.q. laser systems. Based on field tracing techniques and an electromagnetic representation of light, VirtualLab provides fully vectorial results as input for a broad set of merit functions that define the target of optimization problems. Alternatively, the parameter run provides a framework to vary parameters automatically in a predefined or a random way as used for Monte Carlo simulations.

Customized surface profiles, light sources, transmissions and index modulated media. Programmable interface, light source, transmission and index modulated medium allow customizing optical components just by entering a formula. This enables for example the fast modeling of components with user defined freeform diffractive, refractive or hybrid surface profiles.
