RSoft Products: What's New

RSoft Photonic Component Design Suite Version 2018.12

The RSoft Photonic Component Design Suite version 2018.12 introduces new features to advance the design of optics used in augmented reality and virtual reality (AR/VR) systems. The latest RSoft release supports Synopsys’ optical design workflow for nano-textured diffractive optical elements that enable smaller, lightweight AR/VR devices with improved displays and immersive experiences.

Synopsys’ design workflow includes a seamless interface between LightTools software for virtual prototyping of light as it traverses optical and mechanical components in an AR/VR model, and the RSoft tools for fast, rigorous modeling of nano-textured optical structures. LightTools and RSoft provide a unique multi-domain simulation approach that shares Bidirectional Scattering Distribution Function (BSDF) data to help AR/VR device designers achieve superior light extraction efficiency, beam shaping, and color tuning.

In version 2018.12, the RSoft BSDF enhancements provide greater design flexibility and speed with:

  • BSDF files that can be calculated for X-, Y-, or Z-oriented structures
  • Support for LightTools zone rotations in RSoft BSDF user-defined optical properties
  • Expanded azimuthal symmetry support for faster RSoft BSDF calculations
  • Support for non-uniform wavelengths, which is useful for RGB color displays in AR/VR systems

 Same BSDF data used for two property zones (pink boxes). 
One zone has been rotated 15 degrees, and the diffracted orders are seen to rotate as well.

Expanded theta symmetry support for various angles. Saves simulation time for symmetric structures.

BSDF files can now be calculated for structures oriented along the X or Y axis as well. This can be done in both DiffractMOD and FullWAVE.

There is now added support for non-uniform input wavelength for BSDF, useful for RGB color applications.
