MODE

3D CAD Environment and parameterizable simulation objects allow for rapid model iterations.

• Build 1D, 2D or 3D models
• Define custom surfaces and volumes
• Parameterizable simulation objects
• Import from STL, GDSII

Simulate devices fabricated with nonlinear materials or materials with spatially varying anisotropy.

• Choose from a wide range of nonlinear, negative index, and gain models
• Define new material models with flexible material plug-ins

Achieve high accuracy with your simulations, even with coarse meshes, thanks to submesh geometry sensitivity 

• Compatible with dispersive and high-index contrast materials

Uses multi-coefficient models for accurate material modeling over broadband ranges.

• Accurately represent real materials over broad wavelength ranges
• Automatically generate models from sample data, or define the functions yourself.

• Finite Difference Eigenmode (FDE) solver 
• 2.5D variational FDTD (varFDTD) solver
• Bidirectional Eigenmode Expansion (EME) solver

• Solves full vectorial Maxwell’s equations at a single frequency 
• The solver calculates the mode field profiles, effective index, and loss.
• Integrated frequency sweep makes it easy to calculate group delay, dispersion, etc.

• 3D planar waveguide geometry collapsed into 2D effective materials
• Effective material calculated for each unique vertical cross section 
• Ideal for quick optimization of planar waveguide geometries

• Efficient for the design and optimization of long tapers and periodic devices
• Easily scaling up the structure size without recalculating any modes.
• Unlike BPM, which relies on a slowly varying envelope approximation, the EME method makes no such approximations, and is a rigorous technique.

• Bend loss analysis  
• Overlap calculation / analysis
• Modal area analysis
• Helical waveguides
