Reconfigurable Momentum-space vectorial lasing enabled by Quasi-BIC
Hongyu Yuan, Zimeng Zeng, Jiayao Liu +4
Bound states in the continuum (BICs) have enabled lasers with rich momentum-space textures. However, the output patterns of quasi-BIC lasers remain largely static and confined to a…
Reconfigurable and Recyclable Low-Threshold Quasi-BIC Lasers via a Tunable polymer Coating
Xiaolin Wang, Jiayao Liu, Zimeng Zeng +5
Reconfigurable and sustainable microcavity lasers are highly desirable for next-generation integrated photonics. Here, we report a recyclable, low-threshold quasi-bound state in th…
Spatiotemporal Topological Phase Transition in non-Hermitian Photonic System
Zimeng Zeng, Zhuoyang Li, Jiayao Liu +2
While energy band topology in spatial photonic crystals (PCs) and momentum-band topology in temporal crystals have each served as powerful probes of topological phases in their res…
Dual Flat-Bands of Bound State in the Continuum and Radiative Mode via TE-TM Coupling
Jiayao Liu, Zimeng Zeng, Zhuoyang Li +2
A general symmetry-controlled mechanism is proposed for realizing dual flat-bands of bound state in the continuum (BIC) and its radiative counterpart in photonic crystal slabs. By…
