An international research group, led by Macquarie University scientists, has developed a world-first optical fiber technology which can help detect a wide range of gases with unprecedented sensitivity, with potential applications ranging from breath analysis to air-quality monitoring. The discovery, which has been published in the journal Optica, outlines the development of an optical fiber device which encompasses an invisible infrared laser coupled to an ultra-broadband supercontinuum generator – two elements that researchers have never managed to combine to a single optical system before.

“The new supercontinuum technology that we’ve developed is capable of being used to detect an array of gases, including methane, carbon dioxide and nitrous oxide – gases that can be harmful to humans in high levels and have implications in climate change,” explained lead researcher Dr Darren Hudson from Macquarie University.
