Hi all, I need to model stress-induced birefringence effects in optical components such as compounded lens etc. The modeling of stress should be done by FEM or similar method, and then the stress induced birefringence distribution should be transfered to optical design software for modeling of wavefront error/distribution of transmitted light etc. What is the proper software or software combination choice for this purpose (Zemax+Ansys/Comsol, Solidworks+Code V etc)?
There are two steps.
For mechanical stresses, such as from mounting , gravity, or unavoidable forces, NASTRAN and similar finite element mechanical modeling software will calculate the stresses and output files of stress optic tensors. For injection molding stresses, MoldFlow and Timon3D will model injection molding process and output files of stress optic tensors.
Only one ray tracing program will operate on these arrays of stress tensors in a 3D polarization calculation, Polaris-M, developed at the University of Arizona and marketed through Airy Optics in Tucson AZ. I have done this analysis for several lenses successfully.

Hi Igal, I would propose you to use Comsol for your purposes. Comsol provides a large number of possibilities to calculate multiphysics problems (see this one for instance https://www.comsol.ru/paper/download/62349/zeringue_paper.pdf or this https://www.youtube.com/watch?v=BcXA3kXX5Go). These examples present birefringence in optical fibers, maybe there is another proper software for micro-optics.
COMSOL Multiphysics is one of the best tool to tackle both optical design and stress-strain induced birefringence. ZEMAX OpticStudio has the Structural Thermal Optical Performance (STOP) plugin too.
My immediate thought was Comsol first and then Zemax. But I’m very curious to learn what you decided worked the best. Can you update us after you finished the project?
In One-dimensional ZnO exciton polaritons with negligible thermal broadening at room temperature and Dispersion and polarization conversion of whispering gallery modes in nanowires You will find on birefringence modeling in combination with some optical effects. For begining, but for the software I suppose that they are many other influences to betaken into account.
