Multimode Nested Antiresonant Hollow Core Fiber

Journal of Lightwave Technology, 2021
A novel centro-symmetric nested antiresonant fiber (CNAF) design is proposed and investigated numerically for low-loss, multimode applications. Conventional single tube-lattice and nested antiresonant hollow core fibers (ARHCFs) inherently support multiple core modes, but the higher order modes are more prone to coupling to lossy cladding modes ...

Anti-Resonant Hollow Core Fibers

Optical Fiber Communication Conference (OFC) 2019, 2019
Hollow core fibers based on anti-resonant confinement have demonstrated attractive properties including ultrashort pulse delivery, low attenuation at mid-infrared wavelengths, and damage-free delivery of light in the ultraviolet. Their potential for future development is discussed.

Liquid Core Fibers based on Hollow Core Microstructured Fibers

2005 Pacific Rim Conference on Lasers & Electro-Optics, 2006
We propose a new liquid core fiber capable of guiding in low refractive index liquids. The hollow core of a microstructured fiber is filled with water, in which visible light is efficiently guided.

Recent Breakthroughs in Hollow Core Fiber Technology

Optical Fiber Communication Conference (OFC) 2021, 2021
The performance of Hollow Core Fibers has improved dramatically over the last 6 years. We report progress of the most successful design, Nested Antiresonant Nodeless Fiber, with losses of 0.28 dB/km.

Simplified hollow-core photonic crystal fiber

Optics Letters, 2010
An original design of hollow-core photonic crystal fiber composed of a thin silica ring suspended in air by six silica struts is proposed. This structure can be viewed as a simplified Kagomé-lattice fiber reduced to one layer of air holes. By working on the core surround parameters, an efficient antiresonant air guiding was successfully demonstrated ...

Birefringent hollow core fibers

SPIE Proceedings, 2007
Hollow core photonic crystal fiber (HC-PCF), fabricated according to a nominally non-birefringent design, shows a degree of un-controlled birefringence or polarization mode dispersion far in excess of conventional non polarization maintaining fibers.

Hollow-core microstructured polymer optical fiber

Optics Letters, 2006
We have fabricated microstructured polymer optical fibers that guide light in a hollow core using the photonic bandgap mechanism. The hollow core allows the use of polymer fibers to be extended to wavelength ranges where material absorption typically prohibits their use, with attenuation lower than the material loss observed in the infrared.

Polycarbonate hollow-core microstructured optical fiber

Optics Letters, 2008
A hollow-core microstructured polymer optical fiber is fabricated from polycarbonate material and guidance by inhibited coupling in a two-layer structure is demonstrated in two strong transmission bands with minimum losses of 9.0 dB/m at 800 nm and 3.1 dB/m at 1550 nm.

Characteristics of gas breakdown in hollow-core fibers

SPIE Proceedings, 2008
We succeeded in obtaining gas discharge in 250-, 150-, and 50-mum inner-diameter (i.d.) hollow-core fibers (HCFs) by using longitudinal direct current excitation. Stable glow discharges of at least several minutes were observed for these HCFs. A flash glow was also observed for an HCF with an i.d. of ~20 mum. Breakdown of helium and argon gases in a 26.

Non-Idealities in Hollow Core Inhibited Coupling Fibers

2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020
Hollow Core Inhibited Coupling Fibers are experiencing an impressive reduction of their propagation loss. Despite that, there is still a difference between experimental loss and the theoretical minimum defined by confinement loss. This difference is assumed to be due to additional losses caused by geometrical irregularities of the real fibers compared ...
