Spectral imaging paves the way for various fields, particularly in biomedical research. However, spectral imaging, mainly depending on spatial or temporal scanning, cannot achieve high temporal, spatial, and resolution simultaneously. In this study, we demonstrated a silicon real-time ultraspectral chip based reconfigurable metasurfaces, comprising 155,216 ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:mn>356</mml:mn>...
Abstract Metasurfaces have an exceptional capacity to manipulate the phase, amplitude, polarization, or spectrum of light. However, unit cells, meta‐atoms, metasurfaces are conventionally designed using regular shapes, limiting performance improvement. The utilization with freeform shaped meta‐atoms for on‐chip ultraspectral imaging is proposed, where patterns generated controllable feature sizes and boundary curvatures feasible fabrication. These broaden design diversity enrich...
Optical neural networks are considered next-generation physical implementations of artificial networks, but their capabilities limited by on-chip integration scale and requirement for coherent light sources. This study proposes a spectral convolutional network (SCNN) with matter meta-imaging. The optical layer is implemented integrating very large-scale pixel-aligned filters on CMOS image sensor. It facilitates highly parallel vector-inner products incident incoherent natural i.e., the...
In recent years, mobile crowdsensing has emerged as a key technology for digital city construction, which acquires sensing data and mining values with low cost high flexibility. However, limited by the centrality of system, complexity process, uncertainty users, been severely suffering downgrading problems security reliability quality service (QoS). this study, two-stage game involving blockchain technique is proposed to deal QoS in crowdsensing. First, blockchain-based system dual currency...
On-Chip Ultraspectral Imaging In article number 2100663, Jiawei Yang, Kaiyu Cui, Yidong Huang and colleagues demonstrate a snapshot on-chip ultraspectral imager based on freeform metasurfaces with both high spatial resolution of 356 × 436 spectral 0.5 nm, which will provide new paradigm for future intellisense. The shaped meta-atoms are generated proposed general method could be utilized in forward or inverse design other novel metasurfaces.
We proposed an ultracompact on-chip spectrometer based on high-index-contrast grating. Simulation results show that, optical spectra are reconstructed with resolution as high 2 nm and a compact footprint of only 60 μm ×48 μm.
