Topological Microlaser with A non-Hermitian Topological Bulk
Zhitong Li, Xi-Wang Luo, Dayang Lin +5
Bulk-edge correspondence, with quantized bulk topology leading to protected edge states, is a hallmark of topological states of matter and has been experimentally observed in elect…
Higher-order topological corner states induced solely by onsite potentials with mirror symmetry
Ya-Jie Wu, Wen He, Ning Li +2
Higher-order topological insulators have triggered great interests because of exhibitions of non-trivial bulk topology on lower-dimensional boundaries like corners and hinges. Whil…
Active Perovskite Hyperbolic Metasurface
Zhitong Li, Joseph S. T. Smalley, Ross Haroldson +9
A special class of anisotropic media, hyperbolic metamaterials and metasurfaces (HMMs), has attracted much attention in recent years due to its unique abilities to manipulate and e…
Environmentally Stable Room Temperature Continuous Wave Lasing in Defect-passivated Perovskite
Jiyoung Moon, Masoud Alahbakhshi, Abouzar Gharajeh +8
Metal halide perovskites have emerged as promising gain materials for on-chip lasers in photonic integrated circuits (PICs). However, stable continuous wave (CW) lasing behavior un…
Non-Hermitian Photonics based on Charge-Parity Symmetry
Junpeng Hou, Zhitong Li, Qing Gu +1
Parity-time () symmetry, originally conceived for non-Hermitian open quantum systems, has opened an excitingly new avenue for the coherent control of light. By tailor…
Topological bands and triply-degenerate points in non-Hermitian hyperbolic metamaterials
Junpeng Hou, Zhitong Li, Xi-Wang Luo +2
Hyperbolic metamaterials (HMMs), an unusual class of electromagnetic metamaterials, have found important applications in various fields due to their distinctive properties. A surpr…
Room-temperature continuous-wave operation of organometal halide perovskite lasers
Zhitong Li, Jiyoung Moon, Abouzar Gharajeh +5
Solution-processed organic-inorganic lead halide perovskites have recently emerged as promising gain media for tunable semiconductor lasers, and have come to rival inorganic III-V…
