| 1 | Microbubble resonators combined with a digital optical frequency comb for high-precision air-coupled ultrasound detectors显示文摘Fast and sensitive air-coupled ultrasound detection is essential for many applications such as radar,ultrasound imaging,and defect detection.Here we present a novel approach based on a digital optical frequency comb(DOFC)technique combined with high-Q optical microbubble resonators(MBRs).DOFC enables precise spectroscopy on resonators that can trace the ultrasound pressure with its resonant frequency shift with femtometer resolution and sub-microsecond response time.The noise equivalent pressure of air-coupled ultrasound as low as 4.4 m Pa∕pHz is achieved by combining a high-Q(~3×10~7)MBR with the DOFC method.Moreover,it can observe multi-resonance peaks from multiple MBRs to directly monitor the precise spatial location of the ultrasonic source.This approach has a potential to be applied in 3 D air-coupled photoacoustic and ultrasonic imaging. | JINGSHUN PAN BIN ZHANG ZHENGYONG LIU JIAXIN ZHAO YUANHUA FENG LEI WAN ZHAOHUI LI | 2020 | Photonics Research2020，8，3： | 6 |
| 2 | On-chip chalcogenide microresonators with low-threshold parametric oscillation显示文摘Chalcogenide glass (ChG) is an attractive material for highly efficient nonlinear photonics,which can cover an ultrabroadband wavelength window from the near-visible to the footprint infrared region. However,it remains a challenge to implement highly-efficient and low-threshold optical parametric processes in chip-scale ChG devices due to thermal and light-induced instabilities as well as a high-loss factor in ChG films. Here,we develop a systematic fabrication process for high-performance photonic-chip-integrated ChG devices,by which planarintegrated ChG microresonators with an intrinsic quality (Q) factor above 1 million are demonstrated. In particular,an in situ light-induced annealing method is introduced to overcome the longstanding instability underlying ChG film. In high-Q ChG microresonators,optical parametric oscillations with threshold power as low as 5.4 mW are demonstrated for the first time,to our best knowledge. Our results would contribute to efforts of making efficient and low-threshold optical microcombs not only in the near-infrared as presented but more promisingly in the midinfrared range. | BIN ZHANG PINGYANG ZENG ZELIN YANG DI XIA JIAXIN ZHAO YAODONG SUN YUFEI HUANG JINGCUI SONG JINGSHUN PAN HUANJIE CHENG DUKYONG CHOI ZHAOHUI LI | 2021 | Photonics Research2021，9，7： | 4 |

| 4 | Analysis of (210)~Po in Stone Coal Sample of Vanadium Extracting Plant显示文摘Stone coal,as a kind of vanadium bearing shale,is mainly used for vanadium extraction.A vanadium extracting plant was selected to collect stone coal samples.(210)^Po activity concentration in the stone coal samples was analyzed.The pyro-hydro process by which vanadium is extracted from stone coal is applied in the selected plant.The raw material piles at the raw material workshop of the plant were divided into three areas according to its height. | ZHANG Yanqi PAN Jingshun LIAO Haitao HUANG Juan | 2018 | 中国原子能科学研究院年报2018，，1： | 0 |
