Modeling Light-Matter Interaction in Photonics with COMSOL®
Länge: 59:38
Watch this archived webinar, originally hosted by IEEE Spectrum, to learn about modeling light-matter interactions with the COMSOL Multiphysics® software for photonics use cases.
In this presentation, Professor Alex Kildishev from Purdue University shares an approach for accurately modeling linear optical dispersion, nonlinear optics effects, and gain in light-matter interaction. He discusses generalizing numerical descriptions for more efficient photonics time-domain simulations, shares how to modify models with custom equations, and demonstrates modeling optical effects in the time domain.
