photonic bandgap materials

Photonic bandgap materials are special structures designed to control the movement of light, similar to how semiconductors control electrons. They create "gaps" in the range of light frequencies that can pass through them. This means they can block certain wavelengths of light while allowing others to pass, much like a filter. These materials are used in various applications, including lasers, sensors, and optical devices, enhancing the efficiency and performance of technologies that rely on light. Essentially, they enable the manipulation of light in innovative ways for advanced technological applications.
