Enhancements of 3-D Grating Simulation

(August 27, 2010)

The simulation of 3-D grating structures is being considerably enhanced in the forthcoming version of VirtualLab™. Real 3-D grating structures are used more and more extensively for the design of optical components. The rigorous simulation techniques provided by VirtualLab™ give an insight to the op...

VirtualLab™ 4.8 Released

(July 09, 2010)

VirtualLab™ and VirtualLab™ Advanced 4.8 have been released. VirtualLab™ 4.8 extends the flexibility of 2-D grating simulations. Using so called stacks, the period of the structure can be defined by sequences of optical interfaces, including grating, conical, aspherical, sampled and programmable int...

Sources of Grating Toolbox

For most grating simulation sessions, the incident field is the ideal plane wave. You can select the wavelength and polarization, as well as non-polarized light. In addition to the near field analysis, the VirtualLab™ Grating Toolbox includes two more important features: 

  • Gratings analysis for general incident waves, e.g. a Gaussian beam.
  • Simulation of grating dispersion for arbitrary power spectra which can be defined for any source.

Local polarization changes if a sinusoidal grating is illuminated with a 45°-polarized light.
