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.
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?
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 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.
