PCF fibers are endlessly single-mode, (polarization-maintaining, only type PCF-P), specialized photonic crystal fiber cables. They have a Gaussian intensity profile and are equipped with low-stress fiber connectors with end caps. They are a kind of optical waveguides, which are in most cases made of some kind of glass, can potentially be very long (hundreds of kilometers), and are — in contrast to other. Photonic-crystal fiber (PCF) is a class of optical fiber based on the properties of photonic crystals. It was first explored in 1996 at University of Bath, UK. In the present work, the optical properties of the substrate LMA-PCF were investigated, and the metalens, consisting of dielectric.
Optical couplers are passive devices that couple light through waveguides or fibers. They play a very important role in the applications of photonic devices and systems. This study examines the impact of photonic crystal fiber coupler structures on the transmission characteristics and extinction ratios of triple-core couplers for all-optical logic operations, numerically.
