Photonic Crystal Cavity Design Project

Nathaniel Kinsey, Saint Louis University

This application consists of a multi-step simulation to analyze and design a 1-dimensional photonic crystal cavity. It contains two eigen mode solvers, one for the driving waveguide and one for the photonic crystal, to identify the dispersion of the waveguide and the pass/stop bands. It also contains an optimization routine which seeks identifies the best defect size to maximize the electric field in the cavity. Finally, a frequency domain solver is included to determine the transmission of the structure throughout the visible spectrum. The app is intended to be used as a teaching tool in courses related to integrated photonics and nanophotonics.
