Achieving perfect absorption in few-layer two-dimensional (2D) materials plays a crucial role applications such as optoelectronics and sensing. However, the underlying mechanisms of all reported works imply strongly inherent dependence central wavelength on structural parameters. Here, we propose structure-parameter-deviation immune method for achieving at any desired by harnessing toroidal dipole-bound state continuum (TD BIC). We experimentally demonstrate versatile design with...
Objects with different shapes, materials and temperatures can emit distinct polarizations spectral information in mid-infrared band, which provides a unique signature the transparent window for object identification. However, crosstalk among various polarization wavelength channels prevents from accurate detections at high signal-to-noise ratio. Here, we report full-polarization metasurfaces to break inherent eigen-polarization constraint over wavelengths mid-infrared. This recipe enables...
Abstract Contemporary studies in polarization multiplexing are hindered by the intrinsic orthogonality constraints of states, which restrict scope channels and their practical applications. This research transcends these barriers introducing an innovative nonorthogonal polarization-basis approach. Utilizing spatially varied eigen-polarization states within metaatoms, we successfully reconstruct globally that exhibit minimal crosstalk. method not only facilitates generation free-vector...
Abstract In the domain of spectroscopy, miniaturization efforts often face significant challenges, particularly in achieving high spectral resolution and precise construction. Here, we introduce a computational spectrometer powered by nonlinear photonic memristor with WSe 2 homojunction. This approach overcomes traditional limitations, such as constrained Fermi level tunability, persistent dark current, limited photoresponse dimensionality through dynamic energy band modulation driven...

Thanks to the vertically 3-D integration, at either frequency sides achieved by a novel cross-coupling scheme between in-band out-of-band modes single cavity located lower substrate, while far-held realized due symmetric feed radiators on cavity-backed dual-slot upper substrate. In our design, performs not only radiator but also...

Abstract Metasurface provides a powerful platform to correct the chromatic aberration of conventional lenses in flexible, integratable, and ultra‐compact manner. Mid‐wavelength infrared has promised many exciting applications ranged from molecular fingerprint detection low‐light‐level night vision. Developing broadband achromatic metalens mid‐wavelength becomes necessary meet increasingly urgent demands on high performance photonic devices. Here, we demonstrate metalenses 3.5 5 µm with...
Abstract Owing to the large built‐in field for efficient charge separation, heterostructures facilitate simultaneous realization of a low dark current and high photocurrent. The lack an approach engineer depletion region formed across interfaces heterojunctions owing doping differences hinders high‐performance van der Waals (vdW) photodetectors. This study proposes ferroelectric‐controlling photodetector with vertically stacked two‐dimensional (2D) black phosphorus (BP)/indium selenide (In 2...
Enhancing photoluminescence (PL) efficiency in colloidal quantum dots is pivotal for next-generation near-infrared photodetectors, imaging systems, and photonic devices. Conventional methods, especially metal-based plasmonic structures, suffer from large optical losses, which limits their practical use. Here, we introduce a quasi-bound state the continuum (quasi-BIC) metasurface on silicon-on-insulator platform, tailored to provide high-quality factor resonances with minimized losses....
The Jones matrix, with eight degrees of freedom (DoFs), provides a general mathematical framework for the multifunctional design metasurfaces. Theoretically, maximum DoFs can be further extended in spectrum dimension to endow unique encryption capabilities. However, topology and intrinsic spectral responses meta-atoms constrains continuous engineering polarization evolution over wavelength dimension. In this work, forward strategy quickly establish mapping relationships between solutions...
Using the BES-II detector at BEPC Collider, we measured lowest order cross sections and R values (R=σe+e−→hadrons0/σe+e−→μ+μ−0) for inclusive hadronic event production center-of-mass energies of 3.650, 3.6648 3.773 GeV.

Abstract HgCdTe avalanche photodiodes promise various fascinating applications due to the outstanding capability of detecting weak signals or even single photon. However, underlying transport mechanisms diverse dark current components are still unresolved at high reverse bias, thus limiting development high-performance devices. Here, we establish an accurate model demonstrate competitive mechanism between band-to-band and currents in positive-intrinsic-negative structures. Based on...
We demonstrate a novel polarization-resolved device (PRD) with the ability to accurately resolve polarization states via simple measurement process. The PRD is composed of two elaborately designed metalenses, which are capable focusing circularly polarized (CP) lights. Therefore, for an arbitrary light (treated as combination CP lights), discrepancy exhibited on efficiency, inversely provides way calculate ellipticity. With such strategy, generalized form resolving derived, ellipticity...
Abstract Metasurfaces have revolutionized holography by enabling high‐density channel multiplexing, positioning them as promising candidates for applications in full‐color holographic imaging, optical data storage, and encryption. However, conventional non‐interleaved metasurfaces face limitations the number of controllable dimensions, restricting channels available each dimension. Here, a novel high‐dimensional multiplexing scheme is introduced that significantly enhances both capacity...
