Understanding Photonic Crystal Fibers: Structure and Mechanisms
Photonic Crystal Fibers (PCFs)
Photonic Crystal Fibers (PCFs) are a class of optical fibers with a microstructured arrangement of materials, typically consisting of a solid core surrounded by a periodic array of air holes running along the length of the fiber. This periodic microstructure forms a photonic crystal, which enables unique light propagation properties that differ from conventional optical fibers.
Structure of Photonic Crystal Fibers
Core
The central part where light is confined. It can be
