How to Model Optical Anisotropic Media with COMSOL Multiphysics®

December 4, 2017

Erasmus Bartholinus first observed the optical effect of birefringence in 1669. Today, you can observe this effect with a specialized modeling approach for optical anisotropic media.

Silicon Photonics: Designing and Prototyping Silicon Waveguides

September 19, 2017

John Tyndall tried to control the most visible form of energy, light, using 2 buckets and some water. Today, there is a more advanced device for this purpose: a silicon waveguide.

How to Model the Optical Properties of Rough Surfaces

June 6, 2017

We develop a computational model for calculating the optical properties of rough surfaces, such as incident light on a dielectric material with random variations in height and thickness.

How to Implement the Fourier Transformation from Computed Solutions

February 27, 2017

In this wave optics demonstration, learn how to implement the Fourier transformation for computed solutions, using the example of an electromagnetic simulation of a Fresnel lens.

Improving the Design of Monolithically Integrated Magneto-Optic Routers

February 17, 2017

Magneto-optic (MO) routers are an efficient alternative to electro-optic (EO) routers for communication systems. Learn about a modeling approach used by researchers to improve MO router designs.
