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

Wavelength-scalable hollow optical fibres with large photonic bandgaps for CO 2 laser transmission
TL;DR: The design and drawing of a hollow optical fibre lined with an interior omnidirectional dielectric mirror is reported, demonstrating that low attenuation can be achieved through structural design rather than high-transparency material selection.
Journal ArticleDOI
Antiresonant reflecting photonic crystal optical waveguides.
TL;DR: A new regime of guidance is identified in which the spectral properties of these structures are largely determined by the thickness of the high-index layers and the refractive-index contrast and are not particularly sensitive to the period of the cladding layers.

TL;DR: The results demonstrate a unique capability to deliver high-power pulses in a single spatial mode over distances exceeding 200 meters, and represent an increase in the power that can be propagated in an optical fiber of two orders of magnitude.
Capacity Trends and Limits of Optical Communication Networks Discussed in this paper are: optical communication network traffic evolution trends, required capacity and challenges to reaching it, and basic limits to capacity.
TL;DR: The history of traffic and capacity growth and extrapolations for the future, and fibers supporting multiple spatial modes, including multimode and multicore fibers, and the role of digital processing techniques are recounted.

TL;DR: In this article, the authors present a capacity limit estimate of standard and advanced single-mode optical fibers and present elementary capacity considerations for transmission over multiple transmission modes and how it compares to a singlemode transmission.

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.
