Dielectric‐Confinement‐Induced in‐Plane Photoelectric Anisotropy in Isotropic Quasi‐1D γ‐GaS Nanoribbon

open access: yesAdvanced Science, EarlyView.
We investigate the geometry‐governed optoelectronic anisotropy arising from dielectric confinement in quasi‐1D γ‐GaS nanoribbons with intrinsically isotropic atomic structures. Dielectric mismatch between the nanoribbon and its surroundings leads to a general polarization‐dependent photoresponse during near‐field scattering.

Two-Layer Polarization-Maintaining Solid-Core Photonic Crystal Fiber

open access: yesIEEE Photonics Journal, 2018
In this study, a two-layer polarization-maintaining solid-core photonic crystal fiber (SC-PCF) is proposed. The cladding has two large holes both in the first and second layers for high birefringence and confinement loss reduction, respectively.

Toward Intelligent Multimodal Holography for Real‐Time Chemical Imaging of Dynamic Ion Separation

open access: yesAdvanced Intelligent Discovery, EarlyView.
Intelligent multimodal holography integrates digital off‐axis holography, spectroscopic imaging, and AI‐driven reconstruction to visualize ion transport and chemical dynamics in real time. In this perspective paper, we outline how this approach enables label‐free, chemically specific monitoring of complex environments and discuss its potential to ...

Polarization-Sensitive Quantum Optical Coherence Tomography: Birefringence Profiles of Biological Samples

open access: yesApplied Sciences
Polarization-sensitive quantum optical coherence tomography (PS-QOCT) is used to image and characterize birefringence effects in biological samples. Entangled photons are generated via spontaneous parametric down-conversion and split into a reference arm

Differential diagnosis of periapical cyst using collagen birefringence pattern of the cyst wall

open access: yesRestorative Dentistry & Endodontics, 2017
Objectives Periapical lesions, including periapical cyst (PC), periapical granuloma (PG), and periapical abscess (PA), are frequently affected by chemical/physical damage during root canal treatment or severe bacterial infection, and thus, the ...
