Exceptional points in anisotropic planar microcavities
Steffen Richter, Tom Michalsky, Chris Sturm +3
Planar microcavities allow the control and manipulation of spin-polarization, manifested in phenomena like the optical spin Hall effect due to the intrinsic polarization mode split…
Coexistence of strong and weak coupling in ZnO nanowire cavities
Tom Michalsky, Helena Franke, Robert Buschlinger +3
We present a high quality two-dimensional cavity structure based on ZnO nanowires coated with concentrical Bragg reflectors. The spatial mode distribution leads to the simultaneous…
Carrier density driven lasing dynamics in ZnO nanowires
Marcel Wille, Chris Sturm, Tom Michalsky +4
We report on the temporal lasing dynamics of high quality ZnO nanowires using time-resolved micro-photoluminescence technique. The temperature dependence of the lasing characterist…
Study of the Negative Magneto-Resistance of Single Proton-Implanted Lithium-Doped ZnO Microwires
I. Lorite, C. Zandalazini, P. Esquinazi +14
The magneto-transport properties of single proton-implanted ZnO and of Li(7\%)-doped ZnO microwires have been studied. The as-grown microwires were highly insulating and not magnet…
Room-temperature condensation in whispering gallery microresonators assisted by longitudinal optical phonons
Christof P. Dietrich, Rüdiger Schmidt-Grund, Tom Michalsky +2
We report condensation of hexagonal whispering gallery modes (WGM) at room temperature in ZnO microwires that embody nearly perfect polygonal whispering gallery microresonators. Th…
Cavity Polariton Condensate in a Disordered Environment
Martin Thunert, Alexander Janot, Helena Franke +7
We report on the influence of disorder on an exciton-polariton condensate in a ZnO based bulk planar microcavity and compare experimental results with a theoretical model for a non…
Phonon-Assisted Lasing in ZnO Microwires at Room Temperature
T. Michalsky, M. Wille, C. P. Dietrich +4
We report on room temperature phonon-assisted whispering gallery mode (WGM) lasing in ZnO microwires. For WGM laser action on the basis of the low gain phonon scattering process hi…
