A Selective Dispersion–Suppressed Metasurface for Dual‐Polarization and Dual‐Broadband Electromagnetic Window at Large Angles

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
In this manuscript, we propose to suppress the metasurface's undesired dispersion to widen its working range, while preserving the desired one to preserve the function. As shown in the figure, through a method of reversed superimposition (RS), we have implemented the idea on a metasurface for the dual‐band EM window at large angles (≥ 60°).

Enhanced Transport in Organic Semiconductors Mediated Through Interfacial Charge Transfer and Cooperative Strong Coupling

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Here, we experimentally demonstrate the effect of cooperative strong coupling to improve the electron mobility of an organic semiconductor. This is achieved by strong coupling between a highly absorbing organic dye and an organic semiconductor in a MOSFET cavity configuration. Our findings suggest the flexibility of applying cooperative strong coupling

Design, Analysis, and Manufacturing of Diffractive Achromatic Optical Systems

open access: yesMicromachines
The increasing resolution requirements of imaging optical systems must be satisfied by expanding the aperture of the optical system according to Rayleigh’s criterion, and larger apertures of conventional refractive/reflective optics place a greater ...

Printable grayscale nano-template for full-colour organic light-emitting diode near-eye displays with 3D achromatic metalenses

open access: yesNature Communications
Achromatic metalenses are essential for enabling compact, full-color imaging systems in augmented and virtual reality displays. Here, we present printable 3D achromatic metalenses using grayscale electron beam lithography (EBL) and dry etching-based ...

High-performance achromatic flat lens by multiplexing meta-atoms on a stepwise phase dispersion compensation layer

open access: yesLight: Science & Applications
Flat optics have attracted interest for decades due to their flexibility in manipulating optical wave properties, which allows the miniaturization of bulky optical assemblies into integrated planar components.

Intensity-tunable achromatic cascade liquid crystal Pancharatnam-Berry lens

open access: yesCommunications Physics
In the current solution for multiwavelength achromatic flat lenses, a one-to-one correspondence exists between the number of writing phase distributions and the number of achromatic wavelengths.
