| 1 | Biochemical sensing in graphene-enhanced microfiber resonators with individual molecule sensitivity and selectivity显示文摘Photonic sensors that are able to detect and track biochemical molecules offer powerful tools for information acquisition in applications ranging from environmental analysis to medical diagnosis.The ultimate aim of biochemical sensing is to achieve both quantitative sensitivity and selectivity.As atomically thick films with remarkable optoelectronic tunability,graphene and its derived materials have shown unique potential as a chemically tunable platform for sensing,thus enabling significant performance enhancement,versatile functionalization and flexible device integration.Here,we demonstrate a partially reduced graphene oxide(prGO)inner-coated and fiber-calibrated Fabry-Perot dye resonator for biochemical detection.Versatile functionalization in the prGO film enables the intracavity fluorescent resonance energy transfer(FRET)to be chemically selective in the visible band.Moreover,by measuring the intermode interference via noise canceled beat notes and locked-in heterodyne detection with Hz-level precision,we achieved individual molecule sensitivity for dopamine,nicotine and single-strand DNA detection.This work combines atomic-layer nanoscience and high-resolution optoelectronics,providing a way toward high-performance biochemical sensors and systems. | Zhongxu Cao Baicheng Yao Chenye Qin Run Yang Yanhong Guo Yufeng Zhang Yu Wu Lei Bi Yuanfu Chen Zhenda Xie Gangding Peng Shu-Wei Huang Chee Wei Wong Yunjiang Rao | 2019 | Light(Science & Applications)2019，8，1： | 8 |
| 2 | Electrically controllable laser frequency combs in graphene-fibre microresonators显示文摘Laser frequency combs emitting ultrafast pulses of light,at equidistantly discrete frequencies,are cornerstones of modern information networks.In recent years,the generation of soliton combs in microcavities with ultrahighquality factors has established microcombs as out-oflaboratory tools.However,the material and geometry of a laser cavity,which determine comb formation,are difficult to electrically tune.Such dynamic control can further enrich the diversity of comb outputs and help to actively stabilize them. | Chenye Qin Kunpeng Jia Qianyuan Li Teng Tan Xiaohan Wang Yanhong Guo Shu-Wei Huang Yuan Liu Shining Zhu Zhenda Xie Yunjiang Rao Baicheng Yao | 2020 | Light(Science & Applications)2020，9，1： | 5 |

| 4 | Graphene-Fiber Biochemical Sensors: Principles, Implementations, and Advances显示文摘Single atomically thick graphene, with unique structural flexibility, surface sensitivity, and effective light-mater interaction, has shown exceptional advances in optoelectronics. It opens a door for diverse functionalized photonic devices, ranging from passive polarizers to active lasers and parametric oscillators. Among them, graphene-fiber biochemical sensors combine the merits of both graphene and fiber structures, demonstrating impressively high performances, such as single-molecule detectability and fast responsibility. These graphene-fiber biochemical sensors can offer tools in various applications, such as gas tracing, chemical analysis, and medical testing. In this paper, we review the emerging graphene-fiber biochemical sensors comprehensively, including the sensing principles, device fabrications, systematic implementations, and advanced applications. Finally, we summarize the state-of-the-art graphene-fiber biochemical sensors and put forward our outlooks on the development in the future. | Ning AN Chenye QIN Yiwei LI Teng TAN Zhongye YUAN Hao ZHANG Yu WU Baicheng YAO Yunjiang RAO | 2021 | Photonic Sensors2021，11，1： | 0 |
