Quick Specs
Lumerical MODE puts high-accuracy waveguide simulation at the forefront with a Finite Difference Eigenmode (FDE) solver, a variational FDTD (varFDTD) solver, and a Bidirectional Eigenmode Expansion (EME) solver.
Ansys Lumerical MODE
Optical Waveguide & Coupler Solver
Whether you are working on fiber optics or integrated photonics, MODE has everything you need to get the most out of your waveguide and coupler designs.
SOLVE THE UNSOLVABLE
Comprehensive Optical Waveguide Design Environment
MODE enables you to accurately model waveguide and coupler performance. Combining bidirectional Eigenmode expansion, varFDTD, and finite difference eigenmode solvers, MODE can easily handle both large planar structures and long propagation lengths, providing accurate spatial field, modal frequency, and overlap analysis.
