On-chip integrated meta-optics hold great promise in creating highperformance and ultracompact optical display devices. Although previous on-chip metasurfaces for meta-display have predominantly enabled binary-image near-/farfield exhibition functionalities, this remains a challenge and has not been fully explored to induce multiple intensity levels for meticulous grayscale images in an on-chip integrated scheme. Here, we propose and experimentally demonstrate a practical approach to embed a high-resolution grayscale image display into an onchip metasurface integrated on a waveguide in the visible regime. By employing the on-chip meta-diatom interference at the nanoscale, continuous intensity levels of the local optical scattering can be modulated for the out-coupling lightwave to create a high-resolution (pixel size of 440 × 440 nm 2 ) and broadband meticulous grayscale image display. Moreover, directionalselective dual-channel grayscale displays are further expanded by spatially hybridizing the meta-diatom interferences along both x-/ydirections and jointly storing two grayscale images into a single on-chip metasurface pattern. Owing to the on-chip optical propagation scheme, the captured meticulous grayscale display with high fidelity enjoys a high signal-to-noise ratio and large dynamic range uniquely due to zeroth-order diffraction being interference-free. We envision that the proposed meticulous grayscale meta-display driven by an on-chip guided wave allows for their miniaturized integration and promises high-density information storage/encryption, next-generation high-quality miniature displays, and future virtual/augmented reality functionalities.

Arrays of individual atoms trapped in optical microtraps with micrometer‐scale sizes have emerged as a fundamental, versatile, and powerful platform for quantum sciences and technologies. This platform enables the bottom‐up engineering of quantum systems, offering the capability of low‐entropy preparation of quantum states with flexible geometry, as well as manipulation and detection at the single‐site level. The utilization of ultracold itinerant atoms with tunnel coupling in optical microtraps provides new opportunities for quantum simulation, enabling the exploration of exotic quantum states, phases, and dynamics, which would otherwise be challenging to achieve in conventional optical lattices due to high entropy and limited geometric flexibility. Here, the development of tunnel‐coupled optical microtraps for the manipulation of ultracold atomic quantum systems and its recent advances are briefly reviewed.

Sorting nanoparticles is of paramount importance in numerous physical, chemical, and biomedical applications. Current technologies for sorting dielectric nanoparticles have a common size limit and resolution approximately of 20 and 10 nm, respectively. It remains a grand challenge to push the limit. Herein, the new physics that deploys toroidal and multipole responses in a dielectric metasurface to exert strong and distinguishable optical forces on sub‐10 nm nanoparticles is unravelled. The electric toroidal dipole, electric dipole, and quadrupole emerge with distinct light and force patterns, which can be leveraged to promise unprecedented high‐precision manipulations, such as sorting sub‐10 nm polystyrene nanoparticles at 1 nm resolution, sorting 20 nm proteins/exsomes at 3 nm resolution, conveying, and concentrating 100 nm gold nanoparticles. Remarkably, the design can also be employed to screen out medium‐sized nanoparticles from a mixture of nanoparticles with over three sizes. This optofluidic manipulation platform opens the new way to explore intriguing optical modes for the powerful manipulation of nanoparticles with nanometer precisions and low laser powers.
