Photonic Crystal Waveguide

A photonic crystal waveguide is a specially designed structure that guides light with high precision, similar to how a fiber optic cable does. It uses a periodic pattern of materials with different optical properties to control the flow of light, creating a "roadway" for photons. This structure allows engineers to manipulate light very efficiently, enabling faster data transmission and advanced optical devices. Photonic crystal waveguides are key components in technologies like optical communications, sensors, and computing, offering improved performance by controlling light at very small scales.
