Optical Responses From Zero Optical‐Path‐Length Object
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Nanophotonics, Volume 15, Issue 15, 13 August 2026.Directional silver coating breaks lateral mirror symmetry in a reciprocal silica nanograting. Opposite in‐plane illumination directions redistribute optical power differently among diffraction and absorption channels, producing strong polarization‐preserving lateral transmission contrast.

A proposal of a perfect graphene absorber with enhanced design and fabrication tolerance
Scientific Reports, 2017 We propose a novel device structure for the perfect absorption of a one-sided lightwavve illumination, which consists of a high-contrast grating (HCG) and an evanescently coupled slab with an absorbing medium (graphene).

A Scalable Large‐Area Fabrication Strategy for Transparent Polymeric Encapsulated Metagratings
Nanophotonics, Volume 15, Issue 14, 27 July 2026.Transparent encapsulated polymeric guided‐mode resonant metagratings are fabricated by thermal nanoimprint lithography and experimentally validated through structural and optical characterization. The scalable fabrication strategy enables selective RGB reflection and provides a practical route toward large‐area augmented reality and wavelength ...

Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence
IEEE Photonics Journal, 2020 In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, initially, we design a novel two-layer grating with operation in ...

Dynamical Modulation of Dual‐Band Thermal Emission in a Graphene‐2D‐hBN‐LiV2O5 Heterostructure
Nanophotonics, Volume 15, Issue 13, 13 July 2026.A van der Waals heterostructure combining graphene, 2D‐hBN, and LiV2O5 enables dynamically tunable dual‐band mid‐infrared thermal emission with narrow spectral features. Plasmon–phonon strong coupling yields five hybrid polariton branches, whereas coupled‐oscillator models quantify mode mixing and Rabi splittings (up to 27.72 meV via hBN‐thickness ...

Data‐Efficient Electromagnetic Surrogate Solver Through Dissipative Relaxation Transfer Learning
Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.Dissipative relaxation transfer learning (DIRTL) enables data‐efficient training of electromagnetic surrogate solvers by pretraining data generated with artificial material loss before fine‐tuning on target lossless data. The framework suppresses resonant outlier effects during early training, allowing effective adaptation to high‐amplitude resonances ...
