Configuration and Optimization of Grating Systems in Littrow Configuration

[March 04, 2022]
„Littrow configuration” is the name given to those optical systems containing a reflective grating in which the orientation of the grating is such that the working order (most often the first diffraction order) travels back along the direction of the incident beam.

Polarization Analysis of Gratings

[February 28, 2022]
We show the Polarization Analyzer – a powerful tool in the Grating Optical Setup that allows to calculate the efficiencies of grating orders – and investigate the polarization effects of slanted gratings.

System Modeling in K- and X-Domain

[February 18, 2022]
We demonstrate the capabilities of VirtualLab Fusion to automatically select the best-suited Fourier transform algorithm wherever the operation is needed for the simulation, based on accuracy and computational effort criteria which can be adjusted by the user.

Save Your Seat for Our First Webinar and Meetup in 2022 on Lightguides for AR & MR

[January 19, 2022]
Take the opportunity to attend in our Webinar and Meetup in February. During our events, you have the chance to learn more about one of the most exciting developments in optical engineering - light guides for augmented and mixed reality.

Modeling of Lightguide Devices with Complex Expansion Regions in VirtualLab Fusion

[December 17, 2021]
See a Hololens 2-like setup with two EPE for different FOV, and another one illustrating a 2D-periodic diamond-shaped grating in the combined expander/outcoupler region.

Optimization of Grating Geometries in Lightguide Systems

[December 10, 2021]
We address a closely related step in the design workflow: the optimization of the grating geometries used in the coupling and expansion regions of the system. VirtualLab Fusion offers a series of powerful tools for this task.

Performance Investigation of Lightguide Systems

[December 03, 2021]
We demonstrate two examples centered around the performance evaluation of lightguides: an NED (“near to exe”) device with 2D pupil expansion and a human eye model in order to calculate the MTF & PSF, and another one on characterization of the lateral uniformity.

Footprint and Grating Analysis

[November 30, 2021]
This time, we want to highlight the Grating Order Analyzer, which uses the rigorous Fourier Modal Method/Rigorous Coupled Wave Analysis (FMM/RCWA) for grating characterization and illustrate its application in the case of a slanted grating for lightguide incoupling.
