Ansys Lumerical Multiphysics
Photonics Component Simulation Software

Seamlessly design photonic components by capturing multiphysics effects encompassing optical, thermal, electrical, and quantum wells within a unified design environment.

PRECISION MEETS PHOTONIC INNOVATION

Unlock the Power of Multiphysics Component Design with Ansys Lumerical

Ansys Lumerical Multiphysics is the industry’s first multiphysics suite purpose-built for photonic designers. Its unified Finite Element IDE and collection of physics solvers enable designers to accurately model components where the complex interaction of optical, electrical, thermal, and quantum well phenomena is critical to performance. 

Designers can leverage the highly integrated interoperable solvers to address various designs, from photovoltaic cells and image sensors to micro-LEDs, avalanche detectors, modulators, thermal phase shifters, and more.
