Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence

open access: yesIEEE 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

open access: yesNanophotonics, 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 ...

Guided-Mode Resonances in GaN Membrane Grating

open access: yesIEEE Photonics Journal, 2014
This paper proposes guided-mode resonant GaN grating that are implemented on a GaN-on-silicon wafer structure. Numerical simulations based on rigorous coupled wave analysis (RCWA) are performed to model multiple resonances in thick GaN membranes.

Data‐Efficient Electromagnetic Surrogate Solver Through Dissipative Relaxation Transfer Learning

open access: yesAdvanced 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 ...

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 4, Page 1085-1092, July 2026.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Reconciling measured scattering response of 3D metamaterials with simulation

open access: yesEPJ Applied Metamaterials, 2015
Membrane projection lithography is used to create 3-dimensional unit cells in a silicon matrix decorated with metallic inclusions. The structures show pronounced resonances in the 4–16 µm wavelength range and demonstrate direct coupling to the magnetic ...

From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language

open access: yesTransactions of the Philological Society, Volume 124, Issue 2, Page 314-356, July 2026.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

open access: yesAdvanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

open access: yesAdvanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.
