    摘要：The nonlinear up-conversion optical properties of ZnO micro-belt and ZnO Fabry-Pérot（F-P） microcavity were studied by using frequency-resolved interferometric autocorrelation. ZnO micro-belt were prepared by chemical vapor deposition（CVD） method and dry-transferred between a pair of distributed Bragg reflectors（DBR） to form a two-dimensional strongly coupled F-P microcavity. A home-built micro-spectroscopy system was used for interferometric autocorrelation and angle-resolved spectral measurements. The experimental results showed that when pumping ZnO samples with near-infrared ultrafast lasers， both second harmonic generation（SHG） and multi-photon absorption（MPA） upconversion fluorescence signals coexisted. The distinction between SHG and MPA signals could be achieved through different characteristic lines on the frequency spectra. In the case of ZnO F-P microcavity， SHG and MPA signals occupied different emission angles. The competitive relationship between MPA exciton-polaritons and SHG in the strong coupled microcavity system was discussed. Our results provided a reference for the study of microcavity lasers through higher-order nonlinear upconversion methods.

    摘要：Due to the wide direct bandgap （3.37 eV）， large exciton binding energy （60 meV） and excellent optical gain characteristics， zinc oxide （ZnO） becomes an ideal material for low-dimensional and efficient ultraviolet light-emitting and laser devices. Recently， lasing actions have been widely observed in various ZnO microcavities under optical excitation， but the development of electrically pumped devices is the key to their practical application. This review starts with a brief overview of the basic properties of ZnO and common fabrication methods for its micro-/nanostructures， then the recent progresses of light-emitting and laser devices based on ZnO micro-/nanostructures were discussed according to different device architectures. Initially， this review focuses on the progresses of light-emitting and laser devices based on low-dimensional ZnO heterostructures and Schottky structures， alongside the methodologies for the performance optimization. Subsequently， it delves into the current landscape of research pertaining to p-type ZnO materials and their homostructural counterparts in light-emitting and laser applications. Finally， the remaining issues and future development directions of ZnO-based devices have been summarized.

    摘要：Surface-enhanced Raman scattering （SERS） technology is a highly sensitive， selective， and non-destructive spectroscopic analysis method that effectively addresses the challenge of weak Raman scattering signals. Over the past few decades， significant progress has been made in SERS biosensing technology， including the understanding of enhancement mechanisms， development of enhancement materials， preparation of high-performance substrates， and the creation of novel SERS detection technologies and equipment. However， the design and preparation of high-performance SERS substrates and the development of novel SERS detection technologies remain necessary to achieve quantitative biosensing and the identification of complex substances. Whispering gallery mode （WGM） optical microcavities can significantly enhance the interaction between the light field and matter within the cavity. The combination of WGM microcavity and SERS technology can give full play to the synergistic coupling advantages of WGM effect and SERS effect， and it is expected to realize the double enhancement of Raman scattering. In this paper， the SERS enhanced mechanism was elaborated from electromagnetic field enhancement， chemical enhancement and their synergistic enhancement. The SERS enhanced mechanism of semiconductor materials and metal-semiconductor composite system was analyzed with zinc oxide （ZnO） as the representative. The SERS synergism in optical resonator system was discussed， and the recent research progress of WGM microcavity in synergistically enhancing SERS biosensing was reviewed.

    摘要：Brain-like neuromorphic computing is expected to overcome the bottleneck of traditional von Neumann computing architecture， achieving low power consumption and highly efficient information processing， thereby advancing artificial intelligence technology. Artificial synapses are key hardware for building neuromorphic systems， among which photoelectric synapses combine the advantages of electronics and photonics， offering multiple functions such as optical perception， information computation and storage. Emerging all-optically controlled photoelectric synapses， which allow nonvolatile increase and decrease in conductance by optical signals， can effectively prevent damage to the device microstructure caused by electrical signals， improving working stability， and endow synaptic devices with new functions. Oxide is the most widely used artificial synaptic material because of its ease of preparation and good compatibility with CMOS technology. This paper reviews the research progress of all-optically controlled （AOC） oxide synapses with long-term plasticity. The AOC synapses are discussed in terms of conductance modulation methods， including light wavelength and light power density modulation， focusing on device structure， material selection， and photoelectric response mechanism. Finally， we analyze the current challenges faced by all-optically controlled synapses.
