Dynamics of phase defects trapped in optically imprinted orbits in dissipative binary polariton condensate
Jan Wingenbach, Matthias Pukrop, Stefan Schumacher +1
We study the dynamics of phase defects trapped in a finite optically imprinted ring lattice in binary polariton condensates, under the influence of the cross-interaction (CI) betwe…
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…
Manipulating polariton condensates by Rashba-Dresselhaus coupling at room temperature

The ability to control the spin-orbit interaction of light in optical microresonators is of fundamental importance for future photonics. Organic microcrystals, due to their giant o…
All-optical beam steering using the polariton lighthouse effect
Samuel M. H. Luk, Hadrien Vergnet, Ombline Lafont +9
We demonstrate theoretically and experimentally that a specifically designed microcavity driven in the optical parametric oscillation regime exhibits lighthouse-like emission, i.e.…
Switching off microcavity polariton condensate near the exceptional point
Yao Li, Xuekai Ma, Zaharias Hatzopoulos +3
Gain and loss modulation are ubiquitous in nature. An exceptional point arises when both the eigenvectors and eigenvalues coalesce, which in a physical system can be achieved by en…
Atomically thin sheets of lead-free one-dimensional hybrid perovskites feature tunable white-light emission from self-trapped excitons
Philip Klement, Natalie Dehnhardt, Chuan-Ding Dong +8
Low-dimensional organic-inorganic perovskites synergize the virtues of two unique classes of materials featuring intriguing possibilities for next-generation optoelectronics: they…
