Polarization controller for hollow-core fiber
Optics Letters, 2007We demonstrate a universal polarization controller for hollow-core fibers, a simple device consisting of three twisted fiber sections that makes use of the inherent birefringence of the air-core fiber. The device 5% bandwidth at 1550 nm is calculated from measured data to be approximately 13 nm.

Multimode fibers serve as high-resolution imaging probes. We show that a hollow-core fiber solves the problems of high background and limited NA. We experimentally demonstrate high-NA raster-scan and compressive imaging through a hollow-core multimode fiber.

Abstract We propose a new type of hollow-core fiber where the propagation is ensured by a photoinduced self-pattern acting as a surface relief grating (SRG). The SRG is written by launching a suitable laser beam with proper polarization in a capillary glass fiber with the inner surface previously coated with an azopolymer thin film.

Anti-Resonant Hollow Core Fibers
Optical Fiber Communication Conference (OFC) 2019, 2019Hollow 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.

Characteristics of gas breakdown in hollow-core fibers
SPIE Proceedings, 2008We 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.
