Waveguide Gratings

Waveguide gratings are structures that manipulate light within optical devices. Think of them as tiny, carefully designed patterns etched onto a surface, which direct specific wavelengths of light along a narrow pathway called a waveguide. These gratings work by creating interference patterns that reflect or transmit particular colors of light efficiently. They are widely used in telecommunications, sensors, and lasers to filter, split, or direct light signals accurately. By controlling how light interacts with these gratings, engineers can enhance the performance and functionality of optical systems for high-speed data transmission and other applications.
