MODE

MODE

Comprehensive Optical Waveguide Design Environment

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. The Bidirectional Eigenmode expansion and varFDTD engines easily handle both large planar structures and long propagation lengths, providing accurate spatial field, modal frequency, and overlap analysis.

Key Applications

Finite Difference Eigenmode (FDE) 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.

2.5D variational FDTD (varFDTD) solver

  • 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

Bidirectional Eigenmode Expansion (EME) solver

  • 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.
