Quantum PT-Phase Diagram in a Non-Hermitian Photonic Structure
Xinchen Zhang, Yun Ma, Qi Liu +7
Photonic structures have an inherent advantage to realize PT-phase transition through modulating the refractive index or gain-loss. However, quantum PT properties of these photonic…
Simultaneous magnetic and electric Purcell enhancement in a hybrid metal-dielectric nanostructure
Lingxiao Shan, Qi Liu, Yun Ma +5
Hybrid metal-dielectric structures, which combine the advantages of both metal and dielectric materials, support high-confined but low-loss magnetic and electric resonances under d…
Gain-gain and gain-lossless PT-symmetry broken from PT-phase diagram
Qi Zhang, Yun Ma, Qi Liu +5
Parity-time (PT) symmetry and broken in micro/nano photonic structures have been investigated extensively as they bring new opportunities to control the flow of light based on non-…
Nesting and Degeneracy of Mie Resonances of Dielectric Cavities within Zero-Index Materials
Xueke Duan, Haoxiang Chen, Yun Ma +6
Resonances in optical cavities have been used to manipulate light propagation, enhance light-matter interaction, modulate quantum states, and so on. However, in traditional cavitie…
