Light-matter Interaction at Nanoscale

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.
