Parallel bright-field and multi-order edge imaging via wide field-of-view trichannel metalens
Modern optical systems require the capability to perform multi-functional and parallel imaging within compact, integrated architectures. However, conventional refractive lenses are bulky, restricted to single-mode operation, and incompatible with planar integration. In this work, we propose a…

Cavity-assisted nonlocal metasurfaces for momentum-space broadband-operational optical vortice generation with maximum efficiency approaching 80%
Nonlocal metasurfaces generate optical vortices via momentum-space topological singularities, eliminating the need for complex meta-atom phasing or precise beam alignment. Their utility has been constrained by narrow bandwidth and low efficiency stemming from the steep dispersion of high-Q…

Unlocking home-based nocturnal health management: A fiber-optic approach for early detection of cardiorespiratory rhythm disorders
Cardiorespiratory rhythm disorders (CRD) are prevalent yet underdiagnosed conditions with substantial health risks. Current diagnostic methods are limited by invasiveness, intermittent symptom presentation, and low sensitivity during wakefulness. Sleep, by contrast, offers a stable physiological…

A flexible wireless system for prospective photodynamic therapy applications
Cancer treatments, dependent on several factors, deliver varying degrees of treatment effectiveness. Photodynamic therapy (PDT) is a treatment modality that selectively targets and destroys cancer cells using a light-sensitive drug with a specific optical wavelength. However, PDT encounters several…

Metasurfaces forge new paths in quantum spaces
The notion of a path in quantum mechanics has fuelled many debates on the very nature of what quantumness is. Although traditionally associated with physical paths, such as double slits, it can be far more abstract. Now Yan Wang and colleagues demonstrate exotic trajectories in an abstract quantum…

Rayleigh-driven ethanol cluster tracking based on non-contact deep optical molecular diagnosis
Investigating the composition ratio of ethanol–water molecular clusters in air, which are responsible for anisotropic behavior, is a significant challenge, primarily owing to the difficulty of detecting Rayleigh scattering, an inherently weak signal highly susceptible to external interference. This…
