Herein, a general strategy is proposed for developing high-performance transparent synapse array through integration of unidirectional nanowires and transparent electrodes. The device is fabricated via two streamlined steps involving in-plane aligned growth of millimeter-long C8-BTBT nanowires on sapphire substrate through nanogroove-confined recrystallization, followed by shadow-mask-assisted ITO deposition. Replacing opaque metal electrodes with transparent ITO not only preserves optical transparency, but also introduces an oxygen-vacancy-mediated ion–electronic coupling mechanism at the ITO/C8-BTBT interface. The synergistic effect of the ion-electronic dynamics and the aligned nanowire architecture fundamentally tailors carrier relaxation dynamics, delivering a two-orders-of-magnitude extension of persistent photoconductivity, two-fold enhancement in paired-pulse facilitation, two-orders-of-magnitude reduction in energy consumption to picojoule level, and linear conductance modulation with &gt;5000 incremental updates. Furthermore, the transparent synaptic array exhibits unit-to-unit uniformity and enables UV pattern recognition with visional retention exceeding 150 s. Benefiting from the highly linear conductance modulation, the device supports accurate four-function arithmetic operations and UV-encoded International Morse code decoding.

However, their electroluminescence performance and practical implementation are still hindered by nonradiative recombination originating from exciton trapping at defect states among quantum dots (QDs) in the emissive layer (EML). Herein, wide-bandgap ZnS nanocrystals are incorporated into the ZnSeTe EML to suppress nonradiative recombination and modulate carrier transport, thereby improving the performance of blue ZnSeTe QLEDs. The results reveal that the introduction of ZnS nanocrystals effectively suppresses Förster resonance energy transfer among QDs within the EML, leading to an extension of the exciton lifetime in the film from 9.2 to 12.7 ns. Meanwhile, the built-in electric field established at the interface between ZnS nanocrystals and ZnSeTe QDs induces upward band bending in the EML, which lowers the hole injection barrier and facilitates more balanced carrier transport.

In addition, small biological molecules typically absorb in the ultraviolet (UV) range, where high-energy photons would break chemical bonds and risk inducing photodamage. To address the intractable issue, we propose an integrable subwavelength gratings system, dubbed “double twisted grating chiral amplifier (DTGCA)”, which leverages the principle of weak measurement to amplify the circular dichroism (CD) signals. Based on the Kramers-Kronig (KK) relations, we demonstrated a linear correlation between CD and optical rotatory dispersion (ORD) in the off-resonant spectral region far from molecules’ eigenfrequencies. In contrast to contemporary nanoantenna-based amplification which depends on electromagnetic couplings, the DTGCA enables off-resonant enantiomeric ratios discrimination with separation factor exceeding 200.

Achieving holographic multiplexing across different operational spaces with a single metasurface can significantly enhance multiplexing dimensionality and channel capacity. However, limited by guided-wave excitation modes, this approach remains underexplored. This paper proposes a scheme integrating Fresnel (near-field) and far-field holography on a single on-chip metasurface, distributing four multiplexing dimensions across two operational spaces. Using orthogonal detour phases and wavelength-dependent accumulation phases in meta-atom design, we achieve wavelength, direction, and distance multiplexing in the Fresnel region. Furthermore, by linking meta-atom displacement to the incident azimuth of guided waves, far-field multiplexing is extended to wavelength, direction, and azimuth dimensions. As proof of concept, we demonstrate an encryption strategy via simulations of 10-channel Fresnel holography and 2-channel far-field holography. Decryption mandates collaboration of two authorized parties to reconstruct the plaintext in the Fresnel region following the far-field pattern sequence, ensuring high physical security. Since multiplexing dimensions in the two operational spaces differ, the risk of information cross-leakage is effectively mitigated.
