Ching-Cherng Sun
Joint Professor
Ph.D. in Optical Sciences, National Central Univ., Taiwan (1993)
Ching-Cherng Sun received his BS in electrophysics from National Chiao Tung University in 1988 and his Ph.D. in Optical Sciences, from National Central University, in Jan. 1993. In 1996, he joined the faculty of National Central University, Taiwan, and served as an associate professor at the Institute of Optical Sciences. He has become a full professor since 2002. He served as the director of the Innovation and Incubation Center in 2007-2009, and then the chair of Department of Optics and Photonics in 2009-2012. In 2008, he served as the first Director of the Institute of Lighting and Display Science in NCU, which is the first lighting-related institute in Taiwan, and is aimed to support the new technology development in solid-state lighting and display for strong related industry in Taiwan.
In the service of optics community, Prof. Sun was as the chairman of the SPIE Taiwan Chapter in 2002 and 2003. Since 2007, he has served as the Board of Director of the Optical Engineering Society of Taiwan, Taiwan Information Storage Industry Association and Taiwan Illumination Society. He was a Guest Editor of Optical Engineering, is currently an editor of Journal of Holography and Speckles, an associated editor of Applied Optics and one of the Chief Editors in a new journal entitled Journal of Solid-state Lighting by Springer.
Prof. Sun was presented Optical Technology Contribution Award of the Optical Engineering Society of the Republic of China in 2006, the Industry Contribution Award for University by the Ministry of Economic Affair in 2009, the awards for Outstanding Technology to Industry, and the Outstanding Research Award by the National Science Council in 2009, the Outstanding Research Award by Taiwan Information Storage Association in 2012. He is currently a Fellow of the International Society of Optical Engineering (SPIE) and Optical Society of America (OSA), a member of Taiwan Photonics Society, Taiwan Information Storage Industry Association and Taiwan Illumination Society.
Prof. Sun has authored and co-authored more than 110 refereed papers and 250 conference papers. His current major research includes LED solid-state lighting, containing four-level optics design, phosphor model, glare and lighting applications, also holography, holographic storage, photorefractive devices, optical information processing, optical metrology, micro-optics, fiber optics and optical engineering. He has been invited to be a projector leader of three industrial-academic projects sponsored by the Ministry of Economic Affair since 2004 and by National Science Council since 2011. Over the years, Prof. Sun have led a team to make a break-through study in holographic data storage, where the team he led have demonstrated the world-leading highest SNR in the readout signal of the collinear holographic storage, and found a way to compensate thermal expansion. Prof. Sun also has made obvious impact to LED lighting since 2003. He proposed the first precise LED optical model in the world, the first precise optical model for multi-chip white LED, the first precise phosphor model for white LED with silicate phosphor. He published important papers in simulating light extraction efficiency, presenting a white LED in lowest angular CCT deviation. He has been regarded as one of the leading experts in LED solid-state lighting in Taiwan and worldwide optics community.
