Abstract
Recent advances in fabrication technologies along with a range of sophisticated modeling and design tools are enabling the realization of photonic devices with micro and nano-scale structure that can be used to interact guided light with light, liquids or gases to create new classes of light sources and sensing devices.
IPAS brings together research on the development of new classes of optical materials with research in glass extrusion and optical fibre development, notably micro and nanostructuring, surface functionalization and device development. This talk will provide an overview of this research capability and describe recent advances, including optical materials for the mid-infrared, nanoparticles embedded within glass, new classes of chemical and biological sensors (suitable for use in ultra-low volume samples and/or in-vivo), laser devices, and tailored nonlinear effects in novel fibres for optical data processing applications.
Biography: Dr Yinlan Ruan
Dr. Yinlan Ruan gained her Bachelor and Master degree from Huazhong University of Science and Technology, China in 1990s, and her PhD from the Australian National University, Australia in 2005. Dr Ruan’s thesis title was chalcogenide planar waveguide devices for all-optical processing. She had fabricated the low loss chalcognide planar waveguides and photonic crystals by firstly developing compatible semiconductor integration processes. The paper to report this result has been cited for 104 times since its publication in 2004. After her PhD, she joined the photonics group in University of Adelaide, Australia. In the past 6 years, she has engaged four projects including fluoride glass development, biosensing, and subwavelength fibres as an Australian Postdoctoral Fellow. She is currently working in a project to dope diamond nanoparticles into the high index optical fibres and resonant cavities for potential applications in quantum processing and magnetometry. She is also working in other two collaborated projects based on IPAS - upconversion nanoparticles and surface enhanced Raman scattering for biological applications.
Dr Ruan has won Australian Postdoctoral Fellowship (2008-2011), Chinese Government Award for Outstanding Self-financed Students Abroad (2005) and Endeavor Australian Cheung Kong award (2004). She has published 58 papers in refereed journals and conference proceedings. Her research focuses on development of the novel glasses and micro/nano-structured fibers for sensing, microscopy and laser applications.
