3D Printed Hollow-Core Terahertz Fibers [PDF]
Fibers, 2018 This paper reviews the subject of 3D printed hollow-core fibers for the propagation of terahertz (THz) waves. Several hollow and microstructured core fibers have been proposed in the literature as candidates for low-loss terahertz guidance.

Hollow core fiber with an octave spanning bandgap [PDF]
Optics Letters, 2010 We thoroughly compare the out-of-plane bandgaps generated by three realistic two-dimensional lattices: a triangular and a square arrangement of holes and a triangular arrangement of rods. We demonstrate that, for any given hole-diameter-to-pitch ratio d/Lambda, the triangular arrangement of interconnected resonators generates the widest possible ...

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.

Local Energy Velocity of the Air-Core Modes in Hollow-Core Fibers
Photonics, 2023 In this paper, we consider the behavior of the local energy flow velocity of the fundamental air-core mode at the core-cladding boundary in two types of hollow-core fibers: hollow-core fibers with a negative curvature of the core boundary and single ...
