DEVICE

Multiphysics Photonics Design Platform

DEVICE is the world’s first multiphysics simulation suite purpose-built for photonics designers, by photonics designers. Analyze electrical, thermal, and optical effects within a single modeling environment, minimizing time-to-results from complex active devices and opening a reliable path to know-how reuse, deep design automation, and first-time-right development.

  • Built on the finite element drift-diffusion method, the DEVICE Charge Transport Solver provides designers with the correct tools for comprehensive charge transport simulation in active photonic and optoelectronic semiconductor devices.
  • Developed to investigate multiphysics effects occurring in highly integrated optoelectronic devices, the DEVICE Heat Transport Solver provides comprehensive thermal modeling capability, easily handling conductive, convective, and radiative effects, as well as optically and electrically generated heat.
  • Material-adaptive finite element mesh and higher-order mesh polynomial give the DEVICE Finite Element Eigenmode Solver superior accuracy and performance scaling when analyzing waveguide modes, even when geometries or material properties are at play.
  • The DEVICE Discontinuous Galerkin Time Domain Solver tackles the most challenging classes of nanophotonic simulations with a finite element Maxwell’s solver based on the DGTD method, providing superior performance, independent of geometry complexity.
