Several classes of non-planar metallic and dielectric waveguides have been proposed in
the literature for guidance of terahertz (THz) or T-ray radiation. In this review, we focus on the …

This article offers an extensive survey of results obtained using hybrid photonic-crystal fibers
(PCFs) which constitute one of the most active research fields in contemporary fiber optics …

In this paper we demonstrate the light transmission in a spectral range of 2.5 to 7.9 µm
through a silica negative curvature hollow core fiber (NCHCF) with a cladding consisting of …

We first use numerical simulations to show that bending losses of hollow antiresonant fibers
are a strong function of their geometrical structure. We then demonstrate this by fabricating a …

An improved design for hollow antiresonant fibers (HAFs) is presented. It consists of adding
extra antiresonant glass elements within the air cladding region of an antiresonant hollow …

The nonreciprocal propagation of light at the single-photon level is essential for building a
quantum network. Bulk optical schemes are lossy and difficulty to integrate onto a chip. We …

We report on a self-guided microwave surface-wave induced generation of~ 60 μm diameter
and 6 cm-long column of argon-plasma confined in the core of a hollow-core photonic …

Fiber enhanced Raman spectroscopy (FERS) is a powerful multigas analysis technique. It
combines the unmatched analytical prowess of Raman spectroscopy with the enhancement …

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 …

We use numerical simulations to investigate how the curvature of the fiber core boundary
influences the attenuation of hollow antiresonant fibers. We show the importance of a …
