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...
