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...

Tools of Grating Toolbox

The Grating Session Editor assists you in defining your simulation session. Your modeling situation is displayed in a Light Path Diagram and can be edited there. The Parameter Run significantly simplifies systematic investigations of parameter dependencies. This enables you, for instance, to focus on the efficiency or the near field based on the wavelength. This feature is also ideal for evaluating the convergence of your analysis. For instance, you can increase the number of included evanescent fields in the FMM case.


Left: Efficiency of zeroth order for 0 to 200 evanescent fields. Right: Near field of the same simulation, also for 0 to 200 evanescent fields. As you can see, the results converge if more than ca. 120 evanescent fields are calculated.
