Metrology for Quantum Hardware Standardization—Charting a Pathway: A Strategic Review

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1282-1296, September 2026.
Advances in quantum mechanics have long underpinned metrology by enabling practical realizations of units through quantum effects. With the 2019 SI revision, traceability is anchored in defined fundamental constants, reinforcing the quantum‐mechanical basis of modern standards. In parallel, quantum technologies are transitioning from laboratory science

Planar Super‐Oscillation Diffractive Lenses: Practical Developments and Applications

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
This review examines planar super‐oscillation diffractive lenses as a unified framework for super‐oscillatory lenses and supercritical lenses. It focuses on applications in super‐resolution imaging, micro/nanofabrication, and precision measurement and relates their application‐specific requirements to focal‐field control, multiobjective design ...

End‐to‐End Deep Learning Framework for Freeform Metasurfaces via Non‐Uniform Rational B‐Splines Meta‐Atoms

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This work presents a NURBS‐enabled metasurface design framework that combines freeform meta‐atom parameterization with Transformer‐based deep learning. The unified mathematical representation expands geometric degrees of freedom while enabling efficient optical‐response prediction and inverse design.

Large‐Aperture, WFOV Broadband Achromatic Metalens Enabled by Forward Mapping Optimization and Hybrid Algorithmic Framework

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A novel large aperture metalens design strategy achieves broadband achromatic imaging across the visible spectrum (400–680 nm) with a 100° field of view. By incorporating forward mapping optimization and a hybrid algorithm framework, this approach overcomes the limit between aperture size, field of view, and chromatic aberration correction, providing a

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...

Etch‐Less Nanostructures for Photoluminescence Modification From Plasma‐Enhanced Chemical Vapor Deposition‐Grown Silicon Nanocrystals

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
The luminescence from Si‐nanocrystals embedded in a waveguide layer is strongly modified by a shallow photo resist grating on top, which is fabricated by large area laser interference lithography. Guided mode resonances and quasi bound states in the continuum lead to increased upward coupling of radiation, which are also used to experimentally map the ...

TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens

Advanced Science, Volume 13, Issue 46, 17 August 2026.
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.
