Photonics Toys

Photonics Toys is a collection of interactive educational simulations for teaching and learning optics, photonics, and wave physics.

The repository contains browser-based HTML/JavaScript visualizations as well as Python-based educational programs. All simulations are designed for intuitive exploration of physical concepts and are suitable for university-level optics and physics courses.
