Designing Antireflecting Microstructures for Infrared Applications
Explore how 2 microstructure designs can improve the bulk transmittance of silicon (~70%) and cadmium zinc telluride (~79%) to more than 90% within the specific wavelength spectrum.
How to Model Polarization Rotation Along a Waveguide
Interested in modeling photonic waveguiding structures? Learn some efficient techniques for devices with multiple supported waveguide modes and identical waveguide cross sections.
2020 Isaac Newton Medal and Prize Awarded to Nader Engheta
Get an overview of the Isaac Newton Medal and Prize — and the optical physicist who won this year.
Modeling a Scatterer Near an Optical Waveguide
In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
Modeling Waveguides that Support Multiple Modes
2 ways you can model a waveguide that supports multiple modes: add a PML that can be used to absorb any modes, or explicitly add ports for each possible mode.
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…
Computational Electromagnetics Modeling: Which Module to Use?
If you work with a particular electromagnetic device or application area, you might be wondering which module in the COMSOL product suite is right for you. Keep reading for a comprehensive intro.
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.
