Photonic ring

A photonic ring is a tiny circular device that guides light in a continuous loop, like a racetrack for photons (light particles). It’s made of special materials that trap and direct light efficiently, allowing it to interact with signals for applications like filtering or switching in optical communications. By adjusting the properties of the ring, devices can control the flow of light precisely, enabling faster data transmission and advanced sensors. Photonic rings are essential components in modern technologies that rely on manipulating light instead of electricity, offering high performance and miniaturization capabilities.
