The physical origins of extreme cross-polarization extinction in confocal microscopy
Meryem Benelajla, Elena Kammann, Bernhard Urbaszek +1
Confocal microscopy is an essential imaging tool for biological systems, in solid-state physics and nano-photonics. Using confocal microscopes allows performing resonant fluorescen…
The Non-linear Optical Spin Hall Effect and Long-Range Spin Transport in Polariton Lasers
Elena Kammann, Timothy C. H. Liew, Hamid Ohadi +6
We report on the experimental observation of the non-linear analogue of the optical spin Hall effect under highly non-resonant circularly polarized excitation of an exciton polarit…
Spontaneous symmetry breaking in a polariton and photon laser
Hamid Ohadi, Elena Kammann, Timothy C. H. Liew +3
We report on the simultaneous observation of spontaneous symmetry breaking and long-range spatial coherence both in the strong and the weak-coupling regime in a semiconductor micro…
Spinning nanorods - active optical manipulation of semiconductor nanorods using polarised light
C. Robin Head, Elena Kammann, Marco Zanella +2
In this Letter we show how a single beam optical trap offers the means for three-dimensional manipulation of semiconductor nanorods in solution. Furthermore rotation of the directi…
Crossover from exciton-polariton to photon Bose-Einstein condensation
Elena Kammann, Hamid Ohadi, Maria Maragkou +2
BEC of exciton-polaritons and related effects such as superfluidity1,2, spontaneous symmetry breaking3,4 and quantised vortices5,6 open way to creation of novel light sources7 and…
