Abstract Spin–orbit coupling (SOC) in tightly focused optical fields offers a powerful mechanism for manipulating the complex motion of particles. However, to date, such has only been applied single-orbit particles, while multi-orbital dynamics have not yet experimentally demonstrated. Here, theoretical and experimental realization dual-orbit rotational nanoparticles circularly polarized Laguerre-Gaussian beam is reported. Analyses reveal that rotation originates from SOC vortex beam, with...
We report solutions for stable compound solitons in a three-dimensional quasi-phase-matched photonic crystal with the quadratic (χ^{(2)}) nonlinearity. The is introduced checkerboard structure, which can be realized by means of available technology. are built as four-peak vortex modes two types, rhombuses and squares (intersite- onsite-centered self-trapped states, respectively). Their stability areas identified system's parametric space (rhombuses occupy an essentially broader domain),...
In this Letter, we present a binocular chiral metalens (BCM) device designed for four-dimensional (4D) imaging, which integrates both three-dimensional spatial perception and polarization detection. The BCM consists of two identical monocular metalenses that spatially separate left- right-handed circularly polarized (LCP RCP) light. When integrated with commercial camera, the enable simultaneous measurement depth information. Numerical simulations experimental results demonstrate can achieve...
What we believe is a new scheme for producing semidiscrete self-trapped vortices (“swirling photon droplets”) in photonic crystals with competing quadratic ( χ (2) ) and self-defocusing cubic (3) nonlinearities proposed. The crystal designed striped structure, the form of spatially periodic modulation susceptibility, which imposed by quasi-phase-matching technique. Unlike previous realizations optical modes composite media, built as combinations continuous arrayed discrete waveguides, vortex...
The question of how much momentum light carries in media has been debated for over a century. Two rivalling theories, one from 1908 by Hermann Minkowski and the other 1909 Max Abraham, predict exact opposite when enters an optical material: pulling force Minkowski's case pushing Abraham's. Most experimental tests have agreed with theory, but here we report first quantitative evidence Abraham's pressure light. Our results matter optofluidics optomechanics, wherever exerts mechanical pressure.
A cross-band information converter, which links communication and storage modules operating at different wavelengths, is crucial for the development of optical vortex-based networks. However, due to nonlinear efficiency dependence on orbital angular momentum (OAM), traditional intensity or polarization distribution-based recognition distortion emerges. Here, by employing vector vortex with a tailored mode as carrier network, topology one-to-one mapping identification method, we demonstrate...

Differential interference contrast (DIC) imaging is essential in both biological research and medical diagnostics. Despite considerable progress theoretical experimental frameworks, limited by the inefficient cameras, achieving direct DIC with infrared (IR) illumination remains a formidable challenge. However, urgent for diverse fields. Here, we creatively leverage walk-off effect, limitation nonlinear optics, to solve this obstacle present imaging. The critical component of our scheme beam...
Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI the excessive free myoglobin (Mb) in blood circulation. Here, based on concept creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with specificity, affinity, stability, broad species reactivity. A single dose RabMAb injection sufficient for emergency rescue both homologous...

Tiny but universal beam shifts occur when a polarized light is reflected upon planar interface. Although the of Gaussian beams have been measured by weak measurement technique, for orbital angular momentum (OAM)-induced spatial vortex still missing. Here, elaborately choosing preselection and postselection states, tiny OAM-induced Goos–Hanchen Imbert–Fedorov are amplified at an air–prism The maximum along directions both parallel perpendicular to incident plane theoretically predicted...
Skin color detection is an important subject in computer vision research. Color segmentation takes a great attention because effective and robust visual cue for characterizing object from the others. To aim at existing skin algorithms considering luminance information not enough, reliable modeling approach was proposed. It based on fact that distribution of single-colored invariant with respect to variations even Cb-Cr plane does ignore influence Y component YCbCr space. Firstly, according...
