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: A simple robust driver for high-field applications based on this Kagome fibre approach that ensures pulse self-compression down to the ultimate single-cycle limit and provides phase-controlled pulses with up to a 100 μJ energy level, depending on the filling gas, pressure and the waveguide length.

Adaptive Finite Element Method for Simulation of Optical Nano Structures
TL;DR: The finite element method is applied to the optimization of the design of a hollow core photonic crystal fiber and the convergence of the method is looked at to discuss automatic and adaptive grid refinement and the performance of higher order elements.

Hollow-core photonic bandgap fibre: new light guidance for new science and technology.
TL;DR: The HC-PCF fabrication, the different results achieved in the fields of laser-induced particle guidance, low-threshold stimulated Raman scattering in hydrogen (vibrational and rotational), laser frequency metrology and quantum optics are reviewed.

TL;DR: It is concluded that 7-unit-cell cores are currently most suitable for transmission of femtosecond and sub-picosecond pulses, whereas larger cores are better for delivering nanosecond pulsed and continuous-wave beams.

Progress in microstructured optical fibers
TL;DR: The development of microstructured optical fibers has led to the realization of many optical properties in fiber form that were not previously attainable as discussed by the authors, and some of the key applications of micro-structured fibers, including nonlinear fiber-based devices and fibers for high power light delivery, are reviewed.

Full 2-D photonic bandgaps in silica/air structures
