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.
The Nonparaxial Gaussian Beam Formula for Simulating Wave Optics
Here’s your introduction to the nonparaxial gaussian beam formula, which is used for simulating wave optics problems in COMSOL Multiphysics®.
Chasing Waves: The Story of John Scott Russell and the KdV Equation
It all started with a horse: Learn about the history and use cases for solitons, as well as the life and work of the naval architect behind the KdV equation: John Scott Russell.
How to Model Linear and Nonlinear Optics in the COMSOL® Software
See how to model the Kerr effect, and other linear and nonlinear optical phenomena, using the Wave Optics Module and COMSOL Multiphysics®.
How to Use the Beam Envelopes Method for Wave Optics Simulations
In order to simulate optically large optical systems, you need to solve for Maxwell’s equations, which requires a fine mesh and a lot of computational energy. Enter the beam envelope method.
How to Model Optical Anisotropic Media with COMSOL Multiphysics®
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
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.
