Fiber-pigtailing quantum-dot cavity-enhanced light emitting diodes
Lucas Rickert, Frederik Schröder, Timm Gao +3
We report on a process for the fiber-coupling of electrically driven cavity-enhanced quantum dot light emitting devices. The developed technique allows for the direct and permanent…
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…
Spiraling vortices in exciton-polariton condensates
Xuekai Ma, Yaroslav V. Kartashov, Tingge Gao +2
We introduce the phenomenon of spiraling vortices in driven-dissipative (non-equilibrium) exciton-polariton condensates excited by a non-resonant pump beam. At suitable low pump in…
Exciton interaction induced spin splitting in MoS monolayer
Yao Li, G. Li, Xiaokun Zhai +11
By pumping nonresonantly a MoS monolayer at K under a circularly polarized cw laser, we observe exciton energy redshifts that break the degeneracy between B excitons with…
Controllable high-speed polariton waves in a PT-symmetric lattice
Xuekai Ma, Yaroslav Y. Kartashov, Tingge Gao +1
Parity-time (PT) symmetry gives rise to unusual phenomena in many physical systems, presently attracting a lot of attention. One essential and non-trivial task is the fabrication a…
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
E. Estrecho, T. Gao, N. Bobrovska +12
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spon…
