Selective filling of photonic crystal fibres

Autor: Danny Noordegraaf, T.P. Hansen, Kristian Nielsen, Anders Bjarklev, Thorkild Sørensen

Publikováno v: Journal of Optics A: Pure and Applied Optics. 7:L13-L20

A model for calculating the time necessary for filling one or more specific holes in a photonic crystal fibre is made. This model is verified for water, and its enabling potential is illustrated by a polymer application. Selective filling of the core

For development of hollow-core transmission fibers, the realizable fibers lengths, bandwidth, characterization, and compatibility with standard technology are important issues. We report record-length air-guiding fiber, spectral properties, splicing,

Spectral macro-bending loss considerations for photonic crystal fibres

Autor: Erik Knudsen, Stig E. Barkou Libori, T.P. Hansen, Jes Broeng, H.R. Simonsen, J.R. Jensen, A. Bjarklev, Thorkild Sørensen

Publikováno v: IEE Proceedings - Optoelectronics. 149:206-210

Both a scalar method and a fully vectorial method have been applied to modelling the bending losses in photonic crystal fibres (PCFs). Due to a decreasing index difference between the core and the cladding towards short wavelengths, an unusual loss m

To investigate zinc dithiophosphate (ZnDTP) films on iron oxide surfaces by inelastic electron tunneling spectroscopy (IETS), it was necessary to define the conditions required to generate films of usable resistances. In this paper, the results of el

Oxygen status determined by the photo-electric method - a circular finger-probe constructed for detection of blood oxygen content, blood flow and vascular density

Autor: T.P. Hansen, Vagn Hójkær Larsen, Steen Levin Nielsen

Publikováno v: Scandinavian Journal of Clinical and Laboratory Investigation. 53:75-81

Three factors are the major determinants of tissue oxygenation: blood oxygen content, blood flow and vascular density. Blood oxygen content can be measured in vitro by haemoximetry or in vivo by oximetry. The blood flow and the vascular density may b

All-fiber chirped pulse amplification using highly-dispersive air-core photonic bandgap fiber

Autor: C.J.S. de Matos, James Taylor, T.P. Hansen, Jes Broeng, Kim P. Hansen

Publikováno v: Optics express. 11(22)

We show, for the first time to our knowledge, all-fiber chirped pulse amplification using an air-core photonic bandgap fiber. Pulses from a wavelength- and duration-tunable femtosecond/picosecond source at 10 GHz were dispersed in 100 m of dispersion

Passive and active photonic crystal fibres

Publikováno v: SPIE Proceedings.

Photonic Crystal Fibres (PCFs) have appeared as a new class of optical waveguides, which have attracted large scientific and commercial interest during the last years. PCFs are typically microstructured silica waveguides with a large number of air ho
