I want to analyze the waveguide supported modes, to obtain a single mode. What is the difference in using them?

 

thanks.

Hi

I would suggest to post in this in the relevant forum (e.g., Photonics: https://innovationspace.ansys.com/forum/forums/forum/discuss-simulation/photonics/) as the forum here is related to  installation & licensing of our Ansys Teaching and Research products.

All the best

Erik

Dear Subscriber,

• In terms of simulation results, these two solvers should be very similar. Both can calculate mode profiles and effective indices.
• FDE uses a rectangular mesh, while FEEM uses a triangular mesh. This difference means FEEM potentially may be more efficient for waveguides requiring a very fine mesh in specific regions, such as plasmonic waveguides or hollow-core fibers.
• FDE is part of the MODE package, which includes additional features like the mode coupling analysis and EME solver for mode propagation.
• FEEM does not include these features but is bundled with other products in the Multiphysics package (e.g., CHARGE, HEAT, DGTD).
• Since these solvers are part of different packages, they may require separate licenses

Best regards,
Kirill
