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...

Refractive and Diffractive Beam Shaping

The transformation of the Gaussian profile of a coherent laser beam into other profiles like lines, crosses, circular or rectangular top hats and ring type distributions, leads to the design of beam shaping systems. LightTrans has introduced several advanced design techniques to solve a great variety of beam shaping tasks. Our beam shaper modules may be realized by employing refractive or diffractive shaping components. For each application it is critical to consider the pros and cons of both solutions, because they possess different characteristics like sensitivity to variations of the profile and wavelength of the incident beam, and of course to fabrication tolerances. The incident laser beam and/or the transformed beam are allowed to possess divergence angles up to 30° and more. With this feature, beam shaping of diode lasers is possible.
