TLDR
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.Abstract:
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the presence of a full two-dimensional band gap in the photonic crystal cladding Single-mode vacuum waveguides have a multitude of potential applications from ultrahigh-power transmission to the guiding of cold atomsread more

Optical frequency standard using acetylene-filled hollow-core photonic crystal fibers.
TL;DR: A complete experimental investigation of the light-matter interaction between the spatial modes excited in the fibers and the frequency of the locked laser is presented and a simple theoretical model that explains the interaction is also developed.

Thermo-tunable hybrid photonic crystal fiber based on solution-processed chalcogenide glass nanolayers.
TL;DR: A tunable hybrid silica PCF with integrated As2S3 glass nanolayers inside the air-capillaries of the fiber based on a solution-processed glass approach is reported, which could potentially constitute an efficient route towards realization of monolithic tunable fiber filters or sensing elements.

Heterodyne interferometric photothermal spectroscopy for gas detection in a hollow-core fiber
TL;DR: In this paper, the authors used an interband cascade pump laser at 3.6 μm for nitrous oxide (N2O) detection in a hollow-core anti-resonant fiber (HC-ARF) and achieved a normalized noise equivalent absorption coefficient of 7.7×10−9 cm-1WHz-1/2.
Optical trapping and control of nanoparticles inside evacuated hollow core photonic crystal fibers
TL;DR: In this article, an optical conveyor belt for levitated nanoparticles over several centimeters inside both air-filled and evacuated hollow-core photonic crystal fibers (HCPCF) is demonstrated.

All-silica single-mode optical fiber with photonic crystal cladding
TL;DR: The fabrication of a new type of optical waveguide: the photonic crystal fiber that supports a single robust low-loss guided mode over a very broad spectral range of at least 458-1550 nm.

Endlessly single-mode photonic crystal fiber.
TL;DR: An effective-index model confirms that an all-silica optical fiber made by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes can be single mode for any wavelength.

Hollow metallic and dielectric waveguides for long distance optical transmission and lasers
TL;DR: In this paper, the field configurations and propagation constants of a hollow circular waveguide made of dielectric material or metal for application as an optical waveguide were determined and the increase of attenuation due to curvature of the axis was also determined.

Full 2-D photonic bandgaps in silica/air structures
TL;DR: In this paper, full 2D photonic bandgaps are demonstrated for all polarisations in structures with refractive index contrast as small as that of silica and air, and a new type of optical fiber based on these structures is proposed.
