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

TL;DR: The runners-up for Science’s Breakthrough of the Year are the first new great ape species discovered since 1929, a banner year for cryo–electron microscopy, a cultural change in communicating biology papers, an advance in editing DNA and RNA, the approval of a drug to treat any solid cancer that has a particular mutation, and the observation of coherent neutrino scattering using a portable detector.

Pure rotational stimulated Raman scattering in H2-filled hollow-core photonic crystal fibers.
TL;DR: A reliable model for describing the steady-state rotational SRS of hydrogen was established and the influences of various factors was investigated, and can offer guidance for FGRL investigation, particularly for achieving high-efficiency and high-power FGRLs.

Phase sensitivity of fundamental mode of hollow-core photonic bandgap fiber to internal gas pressure
TL;DR: Numerical simulation showed that the observed high sensitivity to pressure is due to the pressure-induced refractive index change of air inside the hollow-core.

Ming-Yang Chen,Rong-Jin Yu +1 more
TL;DR: In this paper, a square-structured photonic bandgap fibers with bandgaps comparable to those of honeycomb structures was constructed, and the bandgap property and field distribution were calculated with the plane-wave expansion approach and the compact two-dimensional finite-difference time-domain method.

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.

Photonic Band Gap Guidance in Optical Fibers
TL;DR: A fundamentally different type of optical waveguide structure is demonstrated, in which light is confined to the vicinity of a low-index region by a two-dimensional photonic band gap crystal.

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.
