Reconfigurable ultrafast perovskite polariton logic gates via nonlinear dynamics

Yuyang Zhang, Zhuoya Zhu, Xin Zeng +14

Exciton-polaritons provide a great platform for developing ultrafast all-optical logic gates for quantum and optical chips. However, progress toward practical polariton logic remai…

Helical polariton lasing from topological valleys in an organic crystalline microcavity

Teng Long, Xuekai Ma, Jiahuan Ren +6

Topological photonics provides an important platform for the development of photonic devices with robust disorder-immune light transport and controllable helicity. Mixing photons w…

Experimental measurement of the divergent quantum metric of an exceptional point

Qing Liao, Charly Leblanc, Jiahuan Ren +6

The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both the Berry curvature, central to the description of topological matter a…

Nontrivial band geometry in an optically active system

Jiahuan Ren, Qing Liao, Feng Li +6

Optical activity (OA), also called circular birefringence, is known for two hundred years, but its applications for topological photonics remain unexplored. Unlike the Faraday effe…

Full Stark Control of Polariton States on a Spin-Orbit Hypersphere

Feng Li, Emiliano Cancellieri, Giuseppe Buonaiuto +3

The orbital angular momentum and the polarisation of light are physical quantities widely investigated for classical and quantum information processing. In this work we propose to…

Interplay between tightly focused excitation and ballistic propagation of polariton condensates in a ZnO microcavity

Rereao Hahe, Christelle Brimont, Pierre Valvin +7

The formation and propagation of a polariton condensate under tightly focused excitation is investigated in a ZnO microcavity both experimentally and theoretically. 2D near-field a…
