Small Structures, Volume 7, Issue 4, April 2026.Highly enhanced directional emission with narrow angular divergence is experimentally demonstrated from InP/ZnS quantum dots (QDs) and CdSe/ZnS QD‐integrated dielectric metasurfaces. The low intrinsic losses of the InP/ZnS QD layer enable significantly higher emission enhancement when the two QD types are coated on the same metasurface.

Advanced Functional Materials, Volume 36, Issue 24, 23 March 2026.Modular diffractive deep neural network metasurfaces encode and reconstruct holograms across layer combinations and wavelengths, enabling secure, multifunctional operation. Each layer acts independently yet composes jointly, yielding up to m(2N −1) channels for m wavelengths and N layers.

Metrology of optically-unresolved features using interferometric surface profiling and RCWA modeling
Optics Express, 2008 Rigorous coupled wave analysis (RCWA) interprets 3D white-light interference microscopy profiles and reveals the dimensions of optically-unresolved surface features. Measurements of silicon etch depth of a 450-nm pitch grating structure correlate to atomic force microscopy with R(2)= 0.995 and a repeatability of 0.11nm. This same technique achieves a

Numerical Estimation of Bending in Holographic Volume Gratings by Means of RCWA and Deep Learning
Applied SciencesIn this paper, we introduce a novel approach to model bending phenomena on holographic volume gratings based on Rigorous Coupled Wave Analysis (RCWA), in which the bending as a phase in the dielectric permittivity expansion is introduced, and the ...
