“…This fact is explained by the resonant coupling of hollow core modes with special type cladding modes. Similar resonance peaks are sometimes observed in the theoretically calculated loss spectra of silica RFs at the long-wavelength edge of the transmission bands [8] (see [4], Figure 4). However, in the case of chalcogenide RFs, the irregularity of the simulated spectra is observed practically always.…”

“…However, fiber bending reveals another important feature of RF: the resonance coupling of the hollow core modes with the cladding capillary modes ( Figure 6). For the first time such, the resonant coupling was found by numerical simulation in [15], and then this effect was experimentally investigated in [8,16,45].…”

Revolver optical fibers (RF) are special type of hollow-core optical fibers with negative curvature of the core-cladding boundary and with cladding that is formed by a one ring layer of capillaries. The physical mechanisms contributing to the waveguiding parameters of RFs are discussed. The optical properties and possible applications of RFs are reviewed. Special attention is paid to the mid-IR hydrogen Raman lasers that are based on RFs and generating in the wavelength region from 2.9 to 4.4 μm.

In hydrodynamics, vortex generation upon the transition from smooth laminar flows to turbulence is generally accompanied by increased dissipation. However, plane vortices can provide transport barriers and decrease losses, as it happens in numerous geophysical, astrophysical flows and in tokamaks. Photon interactions with matter can affectlight transportin waveguides in unexpected and somewhat counterintuitive ways resembling fluid dynamics. Here, we demonstrate dramatic impact of light vortex formation in micro-structured optical fibres on the energy dissipation. We show possibility of vortices formation in both solid core and hollow core fibres on the zero flow lines in the cladding. We find that vortices reduce light leakage by three orders of magnitude, effectively improving wave guiding. A strong light localization based on the same principle can also be achieved in the negative curvature hollow core fibres.

Abstract. We present measurements of the dispersion of two negative curvature fibers at and around 1 μm. These fibers are suitable for beam delivery of both high power and ultrashort pulse lasers with one designed to operate at 1030 nm and the other designed for dual wavelength delivery at 515 and 1030 nm. Both fibers were found to exhibit anomalous dispersion measured to be 2.17 AE 0.25 ps nm −1 km −1 for the fundamental mode rising to 4.69 AE 0.17 ps nm −1 km −1 for the first-order mode in the 1030-nm fiber. Dispersion in the double wavelength fiber was found to be higher at 3.81 AE 0.03 ps nm −1 km −1 for the fundamental mode guiding at 1030 nm.
