Kiriama announces custom-designed polymer optical fibres

Australia - A new plastic optical fibre company was launched the 18th International Conference on Plastic Optical Fibers held in Cockle Bay, Sydney last month. Kiriama ( http:// ) produces custom designed polymer optical fibres, and offers consultancy and Characterisation services. They specialise in microstructured polymer optical fibres.

Launching the company, Professor Ben Eggleton, Director of Sydney University's Institute of Photonics and Optical Science (IPOS), said "Kiriama have a great technology, great people, extensive experience in making different fibre of designs, and unrivalled facilities for modelling and designing fibres For specific applications. It's a pleasure to launch them onto the world stage, and I wish them every success. They have a fantastic opportunity to establish themselves as the world leader in poly speciality plastic optical fibres."

CEO of the company, Dr Alex Argyros, explains that "microstructured polymer optical fibres use patterns of tiny holes that run the full length along the fibre to produce optical effects that are difficult, or in some cases impossible, to produce any other way. This Unique type of fibre was developed at the University of Sydney and we have exclusive access to commercialise the technology. I am pleased to announce that we have already made sales to Europe and the Asia Pacific region and are currently building our order book."

The research underpinning this work has been recognized with the award of prizes including the Eureka Prize, the Australasian Science Prize and the CommsWorld Prize for ICT Innovation.

Microstructured polymer optical fibres represent a new fibre platform, and offers unique advantages for several important applications. "One of the most important in the short term is mechanical strain sensing," says Dr Argyros.

"Optical fibres have long been used for sensing of mechanical strain over extended lengths, such as in bridges or buildings. However because most optical fibres are made of glass, they cannot withstand large strains. By contrast, polymer fibres can withstand strains of 30- 40%. Because we are able to make polymer fibres that are single mode in the visible, something that is hard to do using conventional polymer fibres, we are able to use the best interrogation techniques for our sensors, like gratings and interferometry.

According to Dr Argyros, these large strains are important in applications such as seismic detection and monitoring the performance of windmill rotors. Other applications where microstructured polymer fibres offer unique advantages over conventional technology include biosensing and the transmission of terahertz radiation.

Microstructured fibres are typically made from a single material, with the light guiding properties being determined by the pattern of holes, rather than chemical composition. "This is a key advantage" explains Dr Argyros. "Because we don't have to worry about diffusion Or polymer compatibility issues, we can use a larger range of polymers to make fibres. We are particularly interested in making fibres for high temperature applications. ”
