Magnetically sensitive optical fibre demonstrated

19 January 2018:

A new paper featuring CNBP researchers demonstrates magnetically sensitive nanodiamond-doped tellurite glass fibres. This work is a first step towards magneto-sensitive fibre devices which could be used in medical magneto-endoscopy and remote mineral exploration sensing. First author of the paper is CNBP AI, Dr Yinlan Ruan from the University of Adelaide.

Journal: Scientific Reports.

Publication titleMagnetically sensitive nanodiamond-doped tellurite glass fibers.

Abstract: Traditional optical fibers are insensitive to magnetic fields, however many applications would benefit from fiber-based magnetometry devices. In this work, we demonstrate a magnetically sensitive optical fiber by doping nanodiamonds containing nitrogen vacancy centers into tellurite glass fibers. The fabrication process provides a robust and isolated sensing platform as the magnetic sensors are fixed in the tellurite glass matrix. Using optically detected magnetic resonance from the doped nanodiamonds, we demonstrate detection of local magnetic fields via side excitation and longitudinal collection. This is a first step towards intrinsically magneto-sensitive fiber devices with future applications in medical magneto-endoscopy and remote mineral exploration sensing.

Concordia College visits CNBP

IMG_Georgios-lab_adjustedweb21 September 2015:

Students of Concordia College were left with an improved understanding of nano biophotonics, as well as the opportunities that a science education can provide, following a visit to the CNBP at the University of Adelaide earlier today.

Impressed students were shown around CNBP laboratories by researchers Georgios Tsiminis and Yinlan Ruan, and were also given a number of  presentations, explaining in greater detail what it is that the Centre is hoping to achieve with its multi-disciplinary approach to research.

It is hoped that CNBP visits from Concordia College will be an ongoing activity, helping inspire younger students with a passion for science and technology.
