Introduction to THz Photonic Crystal Fibers Terahertz (THz) photonic crystal fibers (PCFs) have gained significant attention due to their ability to guide electromagnetic waves in the THz frequency range (0.1–10 THz). Unlike conventional dielectric fibers, THz PCFs leverage photonic bandgap (PBG) guidance, hollow-core propagation, and air-clad structures to minimize loss and improve dispersion control. These […]
