HOLLOW-CORE OPTICAL FIBERS: A ROAD
MAP TO MULTIFUNCTIONAL FIBERS
Jonathan Hu

T
his presentation describes the history, guiding mechanism, recent ad-
vances, applications, and future prospects for hollow-core negative cur-
vature 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 awavenumber mismatch between the core and claddingmodes
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, includ-
ing 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.
Jonathan Hu is an associate professor in the department
of electrical and computer engineering at Baylor Univer-
sity. He received his PhD. degree from the University of
Maryland, Baltimore. Before he joined Baylor University
in august 2011, he spent two years as a research asso-
ciate at Princeton University. He has many years of re-
search experience in optical sciences and engineering
with expertise in the areas of chalcogenide glass fibers,
photonic crystal fibers, nanophotonics, 2D materials, and
surface plasmons. He has served as referee for 20 jour-
nals in optics, physics, and materials. He has also been
session chairs for multiple international conferences.
He served as a topic co-chair for Mid Infrared Photonics
(MIP) in the IEEE summer topical meetings (2015) and
a committee member in NOMA Conference in OSA ad-
vanced photonics (2018). He received Baylor Young In-
vestigator Development Award in 2015. He also serves
as a Baylor Fellow in 2018.
