Dr Yuvaraja Visagathilagar, PhD (Australia), BEng(1stc Hons., Australia), FIEAust, SMIEEE, CPEng, NER RPEV RPEQ, APEC Engineer, IntPE(Aus), IEA, PRINCE2, MOSA, LM-MTT, MEDS, MSPIE, MAOS, MANZOS, MAIP, MBCS has over 27+ years of extensive expertise and experience in academia, research, and industry. He graduated with Bachelor of Engineering in Communication Engineering and Doctorate in Engineering (with a highly prestigious scholarship from the Australian Government) in 1996 and 2003 respectively from RMIT University, Melbourne Australia. His dissertation was in “Narrow-band Optical Modulator on Lithium Niobate” for telecommunication applications, but it can be applied for other transceivers applications. In research and industry, he has contributed to over 40+ peer-reviewed international journals and conference pubications. He has visited and presented at universities in USA (i.e. UCLA and UCSD), Peregrine Semiconductor Corporation and in Japan (i.e. Science and technology Organisation).He has collaborated with Defence Science Technology Organisation (now DSTG) in Australia where he has contributed in the design, fabrication, packaging and testing of “High-Speed Lithium Niobate Optical Modulator” including documentation of processes for quality certification (ISO 9001) and flip-chip packaging of narrow-band optical modulators on Lithium Niobate and Ceramic materials. He has extensive academic teaching as a lecturer and post-doctorate research fellow in Photonics, FibreOptics & System, RF System, and Integration where he was involved in research of novel design of narrowband optical modulators. In early years, his research was in Narrow-band Lithium Niobate Modulators but also in finding a solution for packaging of optoelectronic devices (i.e. ceramic and Silicon materials). During the collaboration, he worked with sub-contractors in system integration and packaging of the modulator devices in hermetically sealed packages for defence applications. In 2006, he joined “Future Fibre Technologies Ltd” who are the global leading organisation in optical sensing technologies and has extensive experience over 9 years in optical sensing. He was a senior manager and held positions as Senior Fibre Systems Engineer, R&D Team Leader and Applications Engineering Manager where he contributed in the company products enhancements and novel products design. He has contributed to 2 patent solutions for novel systems in optical fibre sensing and contributed to over 110+ reports with fellow colleagues and R&D teams (not published due to commercial-in-confidence). From July 2016 to March 2018, he was a Senior Academic at RMIT University for postgraduate and undergraduate courses in Electrical Engineering Analysis using Matlab, Electronic Engineering, Radar technologies, Communication systems, Optical/Photonic Engineering, Microwave Circuits & System and Advanced Mathematics for various program levels (or years).
