This mutual interaction gives rise to a family of nonlinear-nonlocal effects which can be studied in the proposed chip-scale photonic circuits. The authors suggest and numerically demonstrate that optically driven liquid deformation can serve as an optical memory capable of storing information and performing neuromorphic computing in a compact actuation region. A key element in the proposed photonic platform is a nanoscale gold patch located on the optical waveguide operating as an optical heater and consequently generating thermocapillary-driven thickness changes in a liquid film covering the waveguide. The image on the cover for Advanced Photonics Volume 4 Issue 4 provides a visual rendering of the process.
Researchers from the National University of Singapore (NUS), Huazhong University of Science and Technology (HUST), Agency for Science, Technology and Research (A*STAR), and Nanyang Technological University (NTU) recently summarized advances in LN photonics in detail in their paper "Advances in lithium niobate photonics: development status and perspectives", Advanced Photonics 4 (3), 034003. (2022). It also includes the integrated LN photonics devices which have appeared in recent years, as well as selected bulk LN based devices and related processing technologies. In this way, the research community can reach a better, comprehensive understanding of the technology evolution of LN photonics.
Recently, in a paper published in High Power Laser Science and Engineering , Vol. 10, Issue, 4 (A. X. Li, C. Y. Qin, et al., Acceleration of 60 MeV proton beams in the commissioning experiment of SULF-10 PW laser, High Power Laser Science and Engineering, 2022, 10(4): 04000e26), a research group from Shanghai Institute of Optics and Fine Mechanics (SIOM) reports the experimental results in the commissioning phase of the 10 PW laser beamline of Shanghai Superintense Ultrafast Laser Facility (SULF), achieving high-energy proton beams with energies up to 62.5 MeV.
We are studying the internal conversion between the two excited states, the highest and directly reachable from the initial ground state being considered as a donor and the lowest as an acceptor.
This paper reviews the relevant research results and state-of-the-art technologies on the silicon photonic chip for scalable quantum applications. Despite the shortcomings, the properties of some components have already met the requirements for further expansion. Furthermore, we point out the challenges ahead and future research directions for on-chip scalable quantum information applications.
Recently, the research group led by Prof. Lu-Jian Chen at Xiamen University (XMU) achieved real-time continuous modulation of the working wavelength in anisotropic polymerized CLC (PCLC) films with a dynamic range of up to 210 nm by using a microfluidics-based "wash-out/refill" strategy. They also demonstrated structural color patterns with reversible changes and multipitch gradients. This work was published in Chinese Optics Letters 2022, Vol. 20, No. 9 (Y. Cao, et al., Dynamic coloration of polymerized cholesteric liquid crystal networks by infiltrating organic compounds) and was selected as the cover of the issue.
In the published paper, the authors show the methods used and the results obtained during the first 10 PW peak power laser demonstration in the world.
The paper proposes and demonstrates a time-resolved single-pixel imaging (TRSPI) technology. This imaging technology is designed for high-speed but periodic scenes. It can realize ultrafast sampling of high-speed targets by fully exploring the spatial correlation information between a dynamic scenes and dynamic coded apertures.
The paper discusses current target delivery strategies and future perspectives to create different permanent magnet guideway (PMG) systems for ICF target transport with levitation from target layering module to the reaction chamber of a laser-driven inertial fusion energy reactor.
Bound states in the continuum (BICs) enable perfect wave localization and significantly enhance light–matter interactions although systems are optically open. Those trapped modes without the leaky-wave radiation in an open continuum are important in numerous applications, including optical nonlinearity, light emitters, and nano-sensors.
