Integrated beam shaping/collimating and customized polarizing edge-emitting lasers with single GaN metasurface

Ti Sun, Jiaqi Song, Wenhui Cao, Xuechang Zhou et autres

Edge-emitting lasers (EELs) have been widely applied in many fields due to the advantages of high power, high efficiency and compactness. However, the propagation angles along the fast and slow axis and the polarization state of the laser in the far field …

Design of circular dichroism filters based on bound states in the continuum

Xuechang Zhou, Chinhua Wang

Optical field manipulation based on the circular dichroism (CD) effect is increasingly demanded in areas such as polarization control, biomolecular sensing, and optical encryption. Due to the weak CD response of natural materials, CD metasurfaces, as ultrathin and designable optical platforms, exhibit …

Force sensing with a graphene nanomechanical resonator coupled to photonic crystal guided resonances

Heng Lu, Tingting Li, Hu Hui, Fengnan Chen et autres

Achieving optimal force sensitivity with nanomechanical resonators requires the ability to resolve their thermal vibrations. In two-dimensional resonators, this can be done by measuring the energy they absorb while vibrating in an optical standing wave formed between a light source and a …

Arbitrary Tuning of Polarization and Circular Dichroism Based on Guided Mode Resonance of Achiral Dielectric Metasurfaces

Xuechang Zhou, Chenqian Wang, Wenbin Huang, Linsen Chen et autres

Abstract Metasurfaces designed for dynamically modulation of strong circular dichroism (CD) hold significant potential in engineering fields such as polarization detection, spectral sensing, and optical communication. Such metasurfaces often require precise and complex chiral structural designs and activation, which limit their practical …

[Clinical and genetic features of persistent asymptomatic microscopic hematuria in children].

Hai-Bo Huang, Xinjiang An, J Y Cui, Chinhua Wang

The most common kidney pathological types in children with persistent asymptomatic microscopic hematuria are minor lesions and TBMD. Children with microscopic hematuria whose first-degree relatives have a family history of hematuria are more likely to have proteinuria and gene variants. COL4A3-5 genetic …
