"Photonic lantern" spectral filters in multi-core fibre
Fibre Bragg gratings are written across all 120 single-mode cores of a multi-core optical fibre. The fibre is interfaced to multimode ports by tapering it within a depressed-index glass jacket. The result is a compact multimode...

Photonic bandgap fiber with multiple hollow cores
We report the fabrication and characterization of the first photonic bandgap fiber with multiple hollow waveguiding cores. Perspectives for scaling to highly multicore designs are discussed.
Single-source AACVD of composite cobalt-silicon oxide thin films
A series of cobalt(II) complexes comprising either triorganosiloxide or tris(tert-butoxy)siloxide ligands have been synthesized and characterized. A mononuclear constitution is enforced through the incorporation of bi- and...
Reducing spectral attenuation in small-core photonic crystal fibers
We describe a modified fabrication process to reduce spectral attenuation in highly nonlinear photonic crystal fibers (PCF) by reducing the effect of OH(-) content in the silica glass. In particular we show outstanding results...

Jan 01, 0001
In this paper the delivery of high power Er:YAG laser pulses through a silica hollow core photonic crystal fibre is demonstrated. The Er:YAG wavelength of 2.94 ím is well beyond the normal transmittance of bulk silica but the...
Minimizing group index variations in a multicore endoscope fiber
J. C. Roper, S. Yerolatsitis, T. A. Birks, B. J. Mangan, C. Dunsby, P. M. W. French, J. C. Knight
Nov 15, 2015
We describe a multicore endoscope fiber where variation in group index is minimized between cores of the fiber, allowing simultaneously launched pulses to arrive at the distal end of the fiber synchronously. Minimization of...
Fabrication of silica hollow core photonic crystal fibres for Er

Jan 01, 0001
In this work we present the fabrication of silica hollow core photonic crystal fibres (HC-PCF) with guidance at 2.94μm. As light is confined inside the hollow core with a very small overlap of the guided E-M wave with the fibre...

Ultrashort pulse compression and delivery in a hollow-core photonic crystal fiber at 540 nm wavelength
Peter James Mosley, W C Huang, Matthew G Welch, Brian J Mangan, William J Wadsworth, Jonathan C Knight
Nov 01, 2010
We have fabricated a bandgap-guiding hollow-core photonic crystal fiber (PCF) capable of transmitting and compressing ultrashort pulses in the green spectral region around 532 nm. When propagating subpicosecond pulses through 1...

Total-evidence framework reveals complex morphological evolution in nightbirds (Strisores)
Strisores is a clade of neoavian birds that include diurnal aerial specialists such as swifts and hummingbirds, as well as several predominantly nocturnal lineages such as nightjars and potoos. Despite the use of genome-scale...
