ECE Colloquium: Heedeuk Shin(POSTECH) “Traveling-wave Photon-phonon interactions for photonic signal processing”
Speaker : Heedeuk Shin
Harnessing well-developed micro-/nano-fabrication technologies to optics makes impossible possible, opening new era of light-matter interaction. At micro/nanoscales, coupling between light and different particle/quasi-particle domains can be enhanced dramatically and controllable with unprecedented design space, and such nano-systems can be integrated with other components on chip. In this talk, I will introduce a novel study about photon-phonon interaction, opto-mechanics. The phenomena of optically driven mechanical vibration have been observed with either extremely high optical power or micro-/nano-sized structures. I will present pioneering demonstrations in opto-mechanics and my recent achievements of hybrid photonic-phononic systems. The controllable photon-phonon interactions in such hybrid systems could provide new science and technologies.
Dr. Heedeuk Shin obtained a Ph.D. in optical science at University of Rochester (USA) under the supervision of Prof. Robert W. Boyd in 2011. From 2011 to 2013, he was a postdoctoral researcher at Sandia National Laboratories in New Mexico and engaged in research of photon-phonon interaction in nano-structures. From 2013 to 2015, he was with Prof. Peter T. Rakich at Yale University as a postdoctoral associate and an Associate Research Scientist of Applied Physics. He joined the Physics department of POSTECH at 2015 as an assistant professor. His research interest is in the fields of experimental demonstration of various Quantum/Nonlinear effects including optomechanical behaviors of silicon nano-structures and quantum integrated circuits.
