Photonic structures

Photonic structures are engineered materials designed to control and manipulate light. They consist of carefully arranged patterns or layers that affect how light travels, reflects, ortransmits through them. Applications include optical fibers, lasers, and sensors, where they improve performance by guiding or filtering specific wavelengths of light. For example, a photonic crystal can block certain colors of light while allowing others to pass, much like a finely tuned filter. These structures enable advances in telecommunications, imaging, and even quantum computing, by providing precise control over light interactions at microscopic scales.
