Photonic Bandgap Structures

Photonic bandgap structures are materials designed to control light similarly to how semiconductors control electrons. They have a repeating pattern that creates specific ranges of light frequencies, called bandgaps, which cannot pass through. This allows engineers to direct, trap, or block certain wavelengths of light precisely. Such structures are used in optical fibers, lasers, and sensors to improve performance by managing light flow with high accuracy. They are fundamental in advancing technologies like efficient communication systems and optical computing.
