The low intrinsic nonlinearity and low signal latency characteristic of Hollow Core Photonic Bandgap Fibers (HC-PBGFs) have fueled strong interest for data transmission applications. Whereas most research to date has looked at improving the optical p

Wide-bandwidth signal transmission with low latency is emerging as a key requirement in a number of applications, including the development of future exaflop-scale supercomputers, financial algorithmic trading and cloud computing. Optical fibres prov

The modal content of 7 and 19 cell Kagomé anti resonant hollow core fibers (K-ARF) with hypocycloid core surrounds is experimentally investigated through the spectral and spatial (Ssup2/sup) imaging technique. It is observed that the 7 and 19 cell K

We review our recent work on the modelling, fabrication and characterization of hollow-core photonic bandgap fibers. We discuss the modal content of these fibers, as well as the opportunities and challenges presented by modal interactions in space di

We present the first detailed investigation of modal properties in hypocycloid Kagome fibers; even with an optimized input launch, higher order modes propagate over long fiber lengths, indicative that these modes have low attenuation.

We study in detail the macrobending effects in a wide transmission bandwidth (~200nm) 19 cell hollow-core photonic bandgap fiber operating at 1550nm. Our results indicate low bend sensitivity over a ~130nm wide interval within the transmission window

We discuss our recent progress in hollow core-photonic bandgap fiber fabrication for high capacity transmission, focusing on two key areas: longitudinal uniformity and length upscaling as well as reviewing highlight results in data transmission.

Current optical reflectometric techniques used to characterize optical fibers have to trade-off longitudinal range with spatial resolution and therefore struggle to provide simultaneously wide dynamic range (>20dB) and high resolution (

SUMMARY Magnetotelluric (MT) data have been acquired across the Samail Ophiolite, Oman mountains, along a 115 km transect in January 2005. Twenty-five MT stations were deployed approximately every 4 km along a profile perpendicular to the coastline n
