Photonic Crystal Fiber

Photonic crystal fiber (PCF) is a type of optical fiber that guides light using a special internal structure of tiny, regularly arranged air holes running along its length. This design creates a unique pathway for light, allowing for better control over its properties, such as speed and confinement. PCFs can reduce signal loss and support a wide range of wavelengths, making them useful in high-speed communications, sensors, and laser applications. Their customizable structure offers advantages over traditional fibers, enabling advanced functionalities in optical technology.
