IPAS High-sensitivity Biosensor research featured in Science Direct

Stephen WSA new biochemical sensor using specialty optical fibre has been developed by an IPAS team at the University of Adelaide. This new sensor is more sensitive than previous designs while still being fully fibre integrated, meaning it can be used directly with standard optical equipment. The sensor has advantages of bio-compatibility, small size, and low cost, yet is robust and simple. It has good potential for biochemical detection in applications that require real-time monitoring and in-field detection. Congratulations Stephen Warren-Smith  and team!

IPAS Photon-Photon Interactions research featured in Physical Review Applied

Chris Perella.Strong photon-photon interactions are a key requirement for numerous quantum communication and computation protocols. Generation of photon-photon interactions mediated by atomic vapours in hollow waveguides has shown great promise, with their efficiencies enhanced by the tight transverse confinement and extended interaction length. We demonstrate, both experimentally and theoretically, the strength of such interactions inside a series of hollow-core photonic crystal fibres and show they only scale with the optical mode diameter, not mode area as might be initially expected, a result of atomic motion within the waveguides. This insight will allow waveguides to be designed to target specific photon-photon interaction strengths.

IPAS Mini Imaging+Sensing Probe Research reported in Optics Letters

mini_probe

Inspiring transdisciplinary photonics researchers, led by Dr Jiawen Li, have invented a world-first tiny fibre-optic probe that can simultaneously measure temperature and see deep inside the body. Combining optical imaging and sensing technologies into a single-fibre-based probe will 1) enable researchers to accurately position sensors under real-time co-localized image guidance and 2) achieve simultaneous imaging and sensing in vivo, which are not accessible using present approaches. Within a week, this paper has reached Altmetric score 89 and ranked No.1 out of all outputs of similar age from Optics Letters.

IPAS Quantum Communications broadcast on Radio Adelaide

To elaborate on the IPAS’s vision and research program, Dr Ben Sparkes, who is working on quantum atom-light interactions at IPAS, was invited for an interview with Radio Adelaide’s Subatomic program with Rohan Neagle. Dr Sparkes discussed the quantum optics research taking place at IPAS and its potential to increase the distance of absolutely-secure quantum communications using our novel hollow-core optical fibres.

Long distance telecom-fiber research featured in OSA

prof-andre-luiten-ctd

Congratulations Prof Andre Luiten for contributing to outstanding research in radio-astronomy. A large team demonstrated for the first time that a clock signal could be sent along 300km of optical fibre and be recovered at the end of the line with very little noise. This enabled a special type of radio-astronomy called Very-Long-Baseline Interferometry (VLBI).

This publication received coverage from several major media outlets such as Business Wire, Science Daily and Photonics Online, potentially reaching over 15 million readers.

IPAS made headlines this week on ABC NEWS

Sparkes_O'Connor

Prof Andre Luiten explained that IPAS’s vision is about exploiting the power of light, to make the world healthier, wealthier and safer. He particularly focused on the critical need for pathways to translate research outcomes from the lab into the real-world.

The segment highlighted two specific projects from the Precision Measurement Group:

The Quantum Mechanics project led by Dr Ben Sparkes, looking at ways to use photonics, or the technology that allows the generation and control of light, to protect sensitive data: a critical feature in applications such as defence and banking.

The Sapphire Clock team, led by Prof Andre Luiten and A/Prof Martin O’Connor,  is building a clock so accurate that it only loses a second once every 40 million years. This has a very important application in supporting Australia’s defence by allowing a performance increase of the Jindalee Over the Horizon Radar.

LIGO & Miniprobes featured in Making a difference – Outcomes of ARC Supported Research

Making the first two pages in the “Making a difference – Outcomes of ARC supported research” publication, Detecting Gravitational Waves  & Smart Needle To Make Brain Surgery Safer were proudly featured in the “Understanding Our World and Translating Fundamental Research” section. This publication is a snapshot of some of the outstanding research outcomes derived from research projects funded by the Australian Government through the Australian Research Council (ARC) National Competitive Grants
Program (NCGP).

ARC

Detecting Gravitational Waves – the most exciting discovery in fundamental physics for decades was firstly announced in 2016 which has opened a new window in astronomy. These discoveries have opened up new possibilities in exploring the universe through its most enigmatic objects: black holes, while at the same time testing our current understanding of the physical laws underpinning the universe. Prof Peter Veitch and A/Prof David Ottaway are leading the Research being carried out at the University of Adelaide node of the new ARC Centre of Excellent for Gravitional Wave Discovery, OzGrav.

Smart Needle To Make Brain Surgery Safer project lead by Prof Robert McLaughlin had developed a revolutionary tiny imaging probe encased within the brain biopsy needle to allow surgeons to avoid  at-risk blood vessels which can potentially fatal. This device contains a tiny fibre-optic camera using shining infrared light and combined with smart image processing software to alert surgeon potentially damaging vessels. Professor Christopher Lind, Consultant Neurosurgeon successfully did a pilot trial with 12 undergoing neurosurgery.

Congratulations to both LIGO and Miniprobes team!
