Key Features

  • Photonic Inverse Design with lumopt
  • Powerful Post-Processing Analysis
  • Nonlinearity and Anisotropy
  • Multi-coefficient Models
  • 3D CAD Environment

Automatically discover optimal designs and geometries for a targeted design goal.  Discover non-intuitive geometries that optimize performance, minimize area, and improve manufacturability.

Powerful post-processing capability, including far-field projection, band structure analysis, bidirectional scattering distribution function (BSDF) generation, Q-factor analysis, and charge generation rate.

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.

Uses multi-coefficient models for accurate material modeling over large wavelengths ranges. Automatically generate models from sample data or define the functions yourself.

FDTD’s CAD environment and parameterizable simulation objects allow for rapid model iterations for 2D and 3D models.
