“…Metasurface-assisted coherent perfect absorption can greatly enhance the efficiency of multiphoton processes. A coherent absorption of NOON states is demonstrated to enhance the absorption efficiency of two-photon states by a factor of 2, compared with the devices based on linear absorption processes − Metasurfaces illuminated by quantum states of light are pushing the LOD of the MNOSs toward the physics limit with weak measurement down to a single photon.…”

Metasurfaces are 2D artificial materials consisting of arrays of metamolecules, which are exquisitely designed to manipulate light in terms of amplitude, phase, and polarization state with spatial resolutions at the subwavelength scale. Traditional micro/nano-optical sensors (MNOSs) pursue high sensitivity through strongly localized optical fields based on diffractive and refractive optics, microcavities, and interferometers. Although detections of ultra-low concentrations of analytes have already been demonstrated, the label-free sensing and recognition of complex and unknown samples remain challenging, requiring multiple readouts from sensors, e.g., refractive index, absorption/emission spectrum, chirality, etc. Additionally, the reliability of detecting large, inhomogeneous biosamples may be compromised by the limited near-field sensing area from the localization of light. Here, we review recent advances in metasurface-based MNOSs and compare them with counterparts using micro-optics from aspects of physics, working principles, and applications. By virtue of underlying the physics and design flexibilities of metasurfaces, MNOSs have now been endowed with superb performances and advanced functionalities, leading toward highly integrated smart sensing platforms.

Multispectral complementary detection technologies have made single-band camouflage materials ineffective, creating strong demand for multispectral compatible camouflage materials. Here, multiscalehierarchical metasurfaces (MHM) compatible with large-area lowcost fabrication are proposed for the first time to realize multispectral camouflage of dual-band lasers, infrared and microwave. The MHM consists of an all-metallic metasurface array (AMMA) and a microwave absorber. The AMMA hinders dual-band lasers and thermal infrared detection, while the microwave absorber beneath the AMMA is applied as a defence against microwave detection. As a proof-of-concept, a MHM sample with an area of 30 × 30 cm 2 and a minimum linewidth of 1.8 µm is fabricated based on nanoimprint lithography. The excellent multispectral camouflage performance is verified in experiments, showing low reflectance (<0.2) in 0.9-1.2 µm and 9-12 µm, low infrared emissivity (<0.2), and high absorption efficiency of over 90% 2.7-26 GHz. Wide-angle and polarizationindependent characteristics are also demonstrated. This work offers a promising opportunity for the engineering application of metasurfaces in the multispectral camouflage field. Moreover, this methodology can be easily extended to other electromagnetic spectrum, providing significant guidance for the design and fabrication of multispectral devices.

The metasurface is a platform with a small footprint and abundant functionalities. With propagation phase and geometric phase, polarization multiplexing is possible. However, different response behaviors of propagation phase and geometric phase to wavelength have not been fully employed to widen the capabilities of metasurfaces. Here, we theoretically demonstrate that metasurfaces can achieve near-field and far-field decoupling with the same polarization at two wavelengths. First, we found a set of pillars whose propagation phase difference between two wavelengths covers the full range of 2π. Then, by rotating pillars to control the geometric phase, the phase at both wavelengths can cover the full range of 2π. Finally, by means of interference principle, arbitrary independent coding for the near field and far field of dual wavelengths is realized. In addition, when the far-field function is focusing, the focused spot is close to the diffraction limit, and, when the NA of the lens is very small, the final output focal length is four times of initial input focal length. This work circumvents the strong wavelength-dependent limitation of planar devices and paves the way toward designing multi-wavelength and multi-functional metadevices for scenarios such as AR applications, fluorescence microscopy, and stimulated emission depletion microscopy.
