FEEM: Waveguide Simulator
FEEM provides superior accuracy and performance scaling with a finite element Maxwell’s solver based on the Eigenmode method. A material-adaptive finite element mesh and the use of higher-order polynomial basis functions make FEEM well suited for highly accurate analysis of waveguide modes in complex geometries and materials.
FEEM is a solver within Lumerical’s DEVICE Multiphysics Simulation Suite, the world’s first multiphysics suite purpose-built for photonics designers. The DEVICE suite enables designers to accurately model components where the complex interaction of optical, electronic, and thermal phenomena is critical to performance. As part of Finite Element IDE, designers can quickly analyze complex active devices while benefiting from Lumerical’s industry-leading usability, performance, and accuracy.
Key FEEM applications include:
- Thermal waveguide tuning
- Passive waveguides and fibers
- Photonic crystal fibers
- GRIN fibers
Finite Element Eigenmode Solver
