Welcome Tianhao Liu to join our group!
Congrat Jiadu, Yang Wang on their paper! Our new paper is online on ACSApplied Materials and Interfaces. We developed a new type of ultrahigh Q silica microcavity device that effectively prevents Q decay over time, enabling long-term staible nonlinear optical performance. Aug 30.
Welcome our new group member Ruoyu Wang! Mr Wang obtained his B.S in Physics from Ocean University of China. Sept 7.
Our research work was published on Nature Photonics! Congrats to all the coworkers! We managed to realize the excitation of an exceptional nonlinear process, named Surface Stimulated Raman Scattering (SSRS), from a single-molecule layer grafted on a on-chip microcavity. The SSRS in turns boosts the Raman lasing performance of the device. Dec 2.
Surface stimulated Raman had been considered to be not possible or challenging, since 1980 after the Bell Laboratory, United States failed to obtain on clear stimulated Raman spectra from molecules on a sapphire surface. From then on, surface nonlinear optics had been solely refered to surface second harmonic generation (SSHG), a well-estiblished surface nonliear optical technique pioneered by Yuen-Ron Shen at UC Berkeley in 1980s.
Unlike traditioal ultrafast laser spectroscopic approaches, whispering gallery mode microresonators offer an otherwise non-achievable platform/tool for the excitation of nonlinear optical processes. Our work is the first demonstration of SSRS nonlinear process.
