Introduction Photonic Crystal Fibers (PCFs) represent one of the most fascinating advancements in fiber optics over the past few decades. Unlike traditional optical fibers that rely solely on core-cladding refractive index differences to guide light, PCFs employ a highly structured arrangement of microscopic air holes running along their length. These microstructures form a periodic dielectric […]
Introduction Photonic crystal fibers (PCFs) represent a transformative class of optical fibers defined by their periodic microstructured arrangement, typically involving air holes running along the length of the fiber. Unlike conventional optical fibers that rely solely on total internal reflection, PCFs can guide light through both index-guiding and photonic bandgap effects, offering an unparalleled level […]
