Attenuation in photonic bandgap guiding hollow-core photonic crystal fiber (HC-PCF) has not beaten the fundamental silica Rayleigh scattering limit (SRSL) of conventional step-index fibers due to strong core-cladding optical overlap, surface roughness at the silica cladding struts, and the presence of interface modes. Hope has been revived recently by the introduction of hypocycloid core contour (i.e., negative curvature) in inhibited-coupling guiding HC-PCF. We report on several fibers with a hypocycloid core contour and a cladding structure made of a single ring from a tubular amorphous lattice, including one with a record transmission loss of 7.7 dB/km at (only a factor above the SRSL) and a second with an ultrabroad fundamental band with loss in the range of 10–20 dB/km, spanning from 600 to 1200 nm. The reduction in confinement loss makes these fibers serious contenders for light transmission below the SRSL in the UV–VIS–NIR spectral range and could find application in high-energy pulse laser beam delivery or gas-based coherent and nonlinear optics.

Fetah BenabidSince their inception, about 20 years ago, hollow-core photonic crystal fiber and its gas-filled form are now establishing themselves both as a platform in advancing our knowledge on how light is confined and guided in microstructured dielectric optical waveguides, and a remarkable enabler in a large and diverse range of fields. The latter spans from nonlinear and coherent optics, atom optics and laser metrology, quantum information to high optical field physics and plasma physics. Here, we give a historical account of the major seminal works, we review the physics principles underlying the different optical guidance mechanisms that have emerged and how they have been used as design tools to set the current state-of-the-art in the transmission performance of such fibers. In a second part of this review, we give a nonexhaustive, yet representative, list of the different applications where gas-filled hollow-core photonic crystal fiber played a transformative role, and how the achieved results are leading to the emergence of a new field, which could be coined “Gas photonics”. We particularly stress on the synergetic interplay between glass, gas, and light in founding this new fiber science and technology.

We report on numerical and experimental studies showing the influence of arc curvature on the confinement loss in hypocycloid-core Kagome hollow-core photonic crystal fiber. The results prove that with such a design the optical performances are strongly driven by the contour negative curvature of the core-cladding interface. They show that the increase in arc curvature results in a strong decrease in both the confinement loss and the optical power overlap between the core mode and the silica core-surround, including a modal content approaching true single-mode guidance. Fibers with enhanced negative curvature were then fabricated with a record loss-level of 17 dB/km at 1064 nm.

Waveguiding mechanism and modal characteristics of hollow core fibers consisting of a single or a regular arrangement of dielectric tubes are investigated. These fibers have been recently proposed as low loss, broadband THz waveguides. By starting from a description in terms of coupling between air and dielectric modes in a single tube waveguide, a simple and useful model is proposed and numerically validated. It is able to predict dispersion curves, high and low loss spectral regions, and the conditions to ensure the existence of low loss regions. In addition, it allows a better understanding of the role of the geometrical parameters and of the dielectric refractive index. The model is then applied to improve the tradeoff between low loss and effectively single mode propagation, showing that the best results are obtained with a heptagonal arrangement of the tubes.

About Me
Luca Vincetti received the Laurea degree in Electronics Engineering (cum laude) and the Ph.D. degree in Information Technologies from University of Parma. In 2000 he was researcher at the National Inter-University Consortium for Telecommunications (Consorzio Nazionale Interuniversitario per le Telecomunicazioni - CNIT), Italy. In 2001 he moved to University of Modena and Reggio Emilia, where he is now Full Professor of Electromagnetic Fields and Photonics.
He has made several key contributions in the development and applications of optical fibers and photonic components. In 2001 he proposed for the first time an exact evaluation of the Jones matrix of a single mode fiber affected by Polarization Mode Dispersion (PMD). In 2000’s he pioneered the use of FEM modal solvers for the analysis of Photonic Crystal Fibers. In 2010 he proposed the basic structure, and the waveguiding model of a new type of hollow core fibers named Tube Lattice Fibers, currently the most promising and studied approach to the realization of very low loss hollow core fibers from terahertz to UV spectral range. He is coauthor of several record loss of hollow-core inhibited-couplings optical fibers. Currently his research is aimed to investigate the waveguiding mechanism and loss mechanisms in hollow core inhibited coupling fibers and to the use of them for terahertz applications, high power laser delivering, lasers, particle accelerators, and quantum applications.
