Longwave infrared spectral imaging (LWIR-SI) has potential in many important civilian and military fields. However, conventional LWIR-SI systems based on traditional dispersion elements always suffer the problems of high cost, large volume complicated system structure. Micro-electro-mechanical Fabry-Perot filtering chips (MEMS-FPFC) give a feasible way for realizing miniaturized, low cost customizable systems. The LWIR MEMS-FPFC ever reported can't meet demands next-generation systems, due...

Electrically driven energy transfer between the surface defect states of ZnO quadrilateral microwires (MWs) and localized plasmon polaritons has been realized by means introducing Au nanoparticles (NPs). An electroluminescence device with green emission using MWs, was fabricated. Once NPs are sputtered on surfaces MWs will shift from to red. Meanwhile, dual emissions were observed sputtering a single MW periodically. Due NPs, electrically mediated can achieve modulation amplifying, or...

Artificial neural networks have acquired remarkable achievements in the field of artificial intelligence. However, it suffers from catastrophic forgetting when dealing with continual learning problems, i.e., loss previously learned knowledge upon new information. Although several algorithms been proposed, remains a challenge to implement these efficiently on conventional digital systems due physical separation between memory and processing units. Herein, software–hardware codesigned...

Directionally scattered surface plasmon polaritons (SPPs) promote the efficiency of plasmonic devices by limiting energy within a given spatial domain, which is one key issues to devices. Benefitting from magnetic response induced in high-index dielectric nanoparticles, unidirectionally SPPs have been achieved via interference between electric and resonances excited particles. Yet, as low-index nanoparticles too weak, directionally are hard detect. In this work, we demonstrate forward single...

Benefitting from high sensitivity, real-time, and label-free imaging, surface plasmon resonance microscopy (SPRM) has become a powerful tool for dynamic detection of nanoparticles. However, the evanescent propagation polaritons (SPPs) induces interference between scattered launched SPPs, which deteriorates spatial resolution signal-to-noise ratio (SNR).
