High temp sensing using suspended-core optical fibers

High Res Edit 008914 April 2016:

CNBP Chief Investigator Tanya Monro and senior researcher Heike Ebendorff-Heidepriem are co-authors on a newly published paper in the Journal ‘Optics Express’.

Publication title: Interferometric high temperature sensor using suspended-core optical fibers.

Authors: Linh Viet Nguyen, Stephen C Warren-Smith, Heike Ebendorff-Heidepriem and Tanya M Monro.

Abstract: We propose and experimentally demonstrate, for the first time to our knowledge, high temperature fiber sensing using the multimode interference effect within a suspended-core microstructured optical fiber (SCF). Interference fringes were found to red-shift as the temperature increased and vice versa. Temperature sensing up to 1100°C was performed by measuring the wavelength shifts of the fringes after fast Fourier transform (FFT) filtering of the spectra. In addition, phase monitoring at the dominant spatial frequency in the Fourier spectrum was used as an interrogation method to monitor various temperature-change scenarios over a period of 80 hours. Our proposed high temperature fiber sensor is simple, cost-effective, and can operate at temperatures beyond 1000°C.

Single-ring hollow core optical fibers produced

Georgios Tsminis_web9 March 2016:

CNBP researchers have published a paper in Optics Express, reporting on the fabrication of the first extruded hollow core optical fiber with a single ring of cladding holes. The fibers were used to perform Raman sensing of methanol, demonstrating their potential for future fiber sensing applications.

Title:  Single-ring hollow core optical fibers made by glass billet extrusion for Raman sensing.

Authors: G. Tsiminis, K. J. Rowland, E. P. Schartner, N. A. Spooner, T. M. Monro and H. Ebendorff-Heidepriem.

Abstract: We report the fabrication of the first extruded hollow core optical fiber with a single ring of cladding holes, and its use in a chemical sensing application. These single suspended ring structures show antiresonance reflection optical waveguiding (ARROW) features in the visible part of the spectrum. The impact of preform pressurization on the geometry of these fibers is determined by the size of the different hole types in the preform. The fibers are used to perform Raman sensing of methanol, demonstrating their potential for future fiber sensing applications.

Funding awarded for new photonic fibre device

cnbplogosquare119 May 2015:

CNBP researchers Dr Jiangbo (Tim) Zhao, Dr Sabrina Heng and A/Prof Heike Ebendorff-Heidepriem have been awarded twenty-two thousand dollars for their project titled ‘Fibre insight in diabetes treatment: a new photonic fibre device to investigate the enteroendocrine L-cell’. The team will design and fabricate a new microstructured optical fibre to study L-cell secretion and provide a means of screening for L-cell stimuli of therapeutic interest.

The project is co-led by Dr. Tim Zhao and Dr. Tongzhi Wu (School of Medicine).

Adelaide node visited by Karen Andrews MP

Andrews 417 April 2015:

CNBP Adelaide node was recently visited by Karen Andrews MP, Parliamentary Secretary to the Minister for Industry & Science.

The visit proved to be a wonderful opportunity to explain in greater detail, the trans-disciplinary work that CNBP is undertaking across the nano biophotonics field, and its particularly advantageous nature to biological and medical research.

As part of the visit, Mrs Andrews met with Centre Director Mark Hutchinson and other senior Centre staff including Heike Ebendorff-Heidepriem, Mel McDowall and Kathy Nicholson, and was shown around several working laboratories to get a flavour of CNBP activity.

Topics discussed with Mrs Andrews included 3D imaging of live and intact cells, sensing technologies for advanced reproductive research, the use of photonics for advanced diagnostics as well as the specific use of lasers and fibre in CNBP related science.

Successful partner launch with Heraeus

Heraeus launch30 March 2015:

CNBP celebrated a successful launch with industry partner Heraeus, in Hanau, Germany on the 30th March 2015.

Taking place at the Heraeus Quarzglas division, the launch was attended by CNBP Investigator A/Prof Heike Ebendorff-Heidepriem and hosted by Dr Gerhard Schoetz, General Manager of Heraeus Specialty Fiber Optics.

As part of the launch, Ebendorff-Heidepriem met with a number of senior Heraeus executives, provided a presentation about the optical fiber sensor research taking place at CNBP, provided an overview of the CNBP (the scope of the research themes and the biological challenges that the CNBP aims to solve), and talked through related photonics research taking place across Australia.

Ebendorff-Heidepriem and Heraeus executives also discussed a wide range of topics during the launch, including the properties of different silica types and behaviors, particularly relating to extrusion and fiber drawing processes. Information on silica items in stock and silica items that could be made on demand was also provided and agreement on the supply of F110 silica rods to fabricate UV transmitting silica fiber was also made.

Heraeus, the world’s largest manufacturer of synthetic fused silica brings to the CNBP longstanding and extensive knowledge in silica glass types and properties. The corporation’s expertise will be critical for the fabrication of specialty silica fibers and for the selection and development of suitable silica types for specific fiber sensor application, for use within the CNBP.

The launch was highly successful, strengthening industry and research links across the CNBP, with the possibility of Heraeus attendance at related Australasian conferences and at the annual CNBP retreat also discussed.
