2 Video Discussions on Multiphysics Simulation of Optics and Photonics
John Wallace, senior editor at Laser Focus World, and Chris Boucher, technical product manager at COMSOL, discuss the use of multiphysics simulation in the optics R&D community. Take a look…
Evanescent Component of the Nonparaxial Gaussian Beam
The evanescent component of the nonparaxial Gaussian beam background field is available as a feature in the Wave Optics and RF modules as of COMSOL Multiphysics® version 5.5.
Modeling the Scattering of Light Off of an Object on a Substrate
A common modeling scenario in wave electromagnetics: computing the scattering of light off of a structure patterned on top of a uniform dielectric substrate.
How to Perform Lens Simulations Using the Wave Optics Module
Lens simulations in wave optics can be difficult to perform, as they usually require a lot of mesh elements. Learn how to sidestep this issue using the functionality of the Wave Optics Module.
What Is the Curl Element (and Why Is It Used)?
When solving some electromagnetics problems, the curl element (also called the edge element or vector element) can be used in the finite element method.
Engineering the Flow of Light Using Photonic Crystals
Did you know that the discovery of photonic crystals in 1980 came about because of an attempt to reduce the losses in semiconductor lasers in a specific frequency range?
Keynote Video: Improving Synchrotron Light Sources with Applications
For synchrotron light sources, brighter is better: RadiaSoft LLC creates and deploys wave optics simulation applications to design improved vacuum chambers for a synchrotron upgrade project.
Calculating the Spectral Properties of an Optical Ring Resonator
The effect of a “whispering gallery” can be observed (a similar way) in another field of science entirely: light waves traveling in an optical ring resonator.
