Silicon Photonics: Designing and Prototyping Silicon Waveguides
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
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
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
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.
How to Couple a Full-Wave Simulation to a Ray Tracing Simulation
Learn how to couple full-wave and ray tracing simulations in a model with a nonhomogenous domain around the antenna. Part 4 of a series on multiscale modeling in high-frequency electromagnetics.
Keynote Video: Solving 2 Transport Process Problems with Simulation
In a keynote presentation from the COMSOL Conference 2016 Boston, Carl Meinhart from the University of California, Santa Barbara and Numerical Design discusses simulating transport processes.
How to Couple Radiating and Receiving Antennas in Your Simulations
Learn how to couple radiating and receiving antennas in your simulations by using the scattered field formulation. Part 3 of a series on multiscale modeling in high-frequency electromagnetics.
Understanding the Paraxial Gaussian Beam Formula
The Gaussian beam is recognized as one of the most useful light sources. To describe the Gaussian beam, there is a mathematical formula called the paraxial Gaussian beam formula. Today, we’ll learn about this formula, including its limitations, by using the Electromagnetic Waves, Frequency Domain interface in the COMSOL Multiphysics® software. We’ll also provide further detail into a potential cause of error when utilizing this formula. In a later blog post, we’ll provide solutions to the limitations discussed here.
