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.

Analyzing the Design of a New Generation of Midinfrared Fiber Optics

April 17, 2017

Semiconductor simulation software is a promising method for advancing the design of midinfrared fiber optics because it can be used to measure propagation losses in the optical fibers.
