Application of Negative Curvature Hollow-Core Fiber in an Optical Fiber Sensor Setup for Multiphoton Spectroscopy [PDF]

Sensors, 2017
In this paper, an application of negative curvature hollow core fiber (NCHCF) in an all-fiber, multiphoton fluorescence sensor setup is presented. The dispersion parameter (D) of this fiber does not exceed the value of 5 ps/nm × km across the optical ...

Ultra-Low-Loss Hollow-Core Bragg Antiresonant Fiber With Super Bandwidth Transmission Window

IEEE Photonics Journal, 2022
A novel hollow-core antiresonant fiber with a Bragg structure is proposed. It is numerically simulated using a commercial finite element method, and optical properties of the fiber, such as mode field, confinement loss, and bend loss, are numerically ...

All-fiber hollow-core fiber gas cell [PDF]

Optical Fiber Technology, 2023
We present a hollow-core fiber (HCF) gas cell with light launched and collected via standard solid-glass core single-mode fibers (SMFs). Gas delivery is realized via a 100μm gap between the SMF and HCF with light low-loss coupling optimized for such a gap.

Theoretical analysis of backscattering in hollow-core antiresonant fibers

APL Photonics, 2021
We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,
