Optical fiber with dual cores suspended in air

We report the successful fabrication of a new type of dual core fiber, comprising 2 optical cores suspended in air. The cores are sub-micron in size, each held in place by 2 thin glass membranes attached to the cladding. The successful realisation of this fiber should open up a range of interesting applications in a variety of different areas.

Optimising the Performances of Hollow Antiresonant Fibres
Francesco Poletti1, John R. Hayes1, David Richardson1; 1Optoelectronics Research Centre, University of Southampton, United Kingdom.
We study the loss of novel antiresonant hollow-core fibres, demonstrate the existence of a wavelength independent optimum distance between core-surround and solid outer cladding, and provide useful guidelines for the fabrication of practical low-loss fibres.

 Kagome-lattice fibers with different number of cladding layers have been investigated. Adding at least two layers decreases the bending sensitivity by more than one order of magnitude, resulting on tiny effects in the fundamental band.

Sy Dat Le1,2, Duc Minh Nguyen1,2, Monique Thual1,2, Laurent Bramerie1,2, Marcia Costa e Silva1,2, Kevin Lenglé1,2, Mathilde Gay1,2, Thierry Chartier1,2, Laurent Brilland3, David Méchin3, Perrine Toupin1,4, Johann Troles1,4; 1Université européenne de Bretagne, France; 2CNRS Foton (UMR 6082), France; 3PERFOS, France; 4CNRS Sciences Chimiques de Rennes (UMR 6226), France.
We report a chalcogenide suspended-core fiber with a record Kerr-nonlinearity of 46 000 W-1km-1 and attenuation of 0.9 dB/m. Four-wave-mixing efficiencies of -5.6 dB at 10 GHz and -17.5 dB at 42.7 GHz are obtained.

First Ignition of an UV Microwave Microplasma in Ar-filled Hollow-Core Photonic Crystal Fibers
Benoît Debord1, Frédéric Gérôme1, Raphael Jamier1, Caroline Boisse-Laporte2, Philippe Leprince2, Olivier Leroy2, Jean-Marc Blondy1, Fetah Benabid1; 1Xlim research Institute, France; 2LPGP, France.
 We report on the first ignition of efficient and stable microwave columns of microplasmas directly inside large Ar-filled hollow-core photonic crystal fibers. Optical characterizations of UV guided light are also presented.
Mo.2.LeCervin.6 • 18:00 (Invited)
John Ballato1,2, Stephanie Morris1,2, Thomas Hawkins1,2, Paul Foy1,2, Colin McMillen2, Roger Stolen1,2, Robert Rice3; 1Center for Optical Materials Science and Engineering Technologies (COMSET), USA; 2School of Materials Science and Engineering, Clemson University, USA; 3Northrup Grumman Space Technology, USA.
Progress in the synthesis and properties of crystalline semiconductor core optical fibers is reviewed. This new class of optical fibers may significantly advance the fields of nonlinear fiber optics and infrared power delivery.
