Abstract:

This presentation describes the history, guiding mechanism, recent advances, applications, and future prospects for hollow-core negative curvature fibers. One-dimensional slab waveguides, two-dimensional annular core fibers, and negative curvature tube lattice fibers are used to illustrate the inhibited coupling guiding mechanism. Antiresonance in the glass at the core boundary and a wavenumber mismatch between the core and cladding modes inhibit coupling between the modes and have led to remarkably low loss in negative curvature fibers. This presentation will explain recent advances in negative curvature fibers that improve the performance of the fibers, including negative curvature that increases confinement, gaps between tubes that increase confinement and bandwidth, additional tubes that decrease mode coupling, tube structures that suppress higher-order modes, nested tubes that increase guidance, and tube parameters that decrease bend loss. Recent applications of hollow-core fibers are also presented, including mid-infrared fiber lasers, micromachining, and surgical procedures. Future prospects for hollow-core fibers will be given at the end.
