       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.

Xiaoqin Shen gave an invited talk at Institute of Chemistry, CAS, Beijing (中科院化学所). Nov 29. 

Xiaoqin Shen gave an oral presentation in The 12th International Photonics and OptoElectronics Meeting (POEM 2019), Wuhan, Hubei. Nov 14.

Xiaoqin Shen gave an invited talk at Wuhan National Laboratory for Optoelectronic (武汉光电国家研究中心). Nov 13.

Our paper published on Physical Review Letters was featured on cover(封面报道)and highlighted as editor's suggestion. Oct 25.Xiaoqin Shen gave an invited talk at the Microcavity Workshop, Photonics Asia 2019(亚洲光电子会议), Hangzhou, Zhejiang. Oct 20.

Our recent work collaborated with Yunfeng Xiao’s group at PKU was just accepted by Physical Review Letters, titled “Microcavity nonlinear optics with an organically functionalized surface”. Congratulations to all the coworkers!  Oct 1. 

Xiaoqin Shen gave an invited talk on 2019 Microcavity Photonics Symposium, Nankai University, Tianjin. Jun 2.
