Polariton ring condensates and sunflower ripples in an expanding quantum liquid
Gabriel Christmann, Guilherme Tosi, Natalia G. Berloff +5
Optically pumping high quality semiconductor microcavities allows for the spontaneous formation of polariton condensates, which can propagate over distances of many microns. Tightl…
Sculpting oscillators with light within a nonlinear quantum fluid
G. Tosi, G. Christmann, N. G. Berloff +5
Seeing macroscopic quantum states directly remains an elusive goal. Particles with boson symmetry can condense into such quantum fluids producing rich physical phenomena as well as…
Oriented polaritons in strongly-coupled asymmetric double quantum well microcavities
Gabriel Christmann, Alexis Askitopoulos, George Deligeorgis +4
Replacing independent single quantum wells inside a strongly-coupled semiconductor microcavity with double quantum wells produces a special type of polariton. Using asymmetric doub…
Bragg Polaritons: Strong Coupling and Amplification in an Unfolded Microcavity
A. Askitopoulos, L. Mouchliadis, I. Iorsh +5
Periodic incorporation of quantum wells inside a one--dimensional Bragg structure is shown to enhance coherent coupling of excitons to the electromagnetic Bloch waves. We demonstra…
Spontaneous Polarisation Build up in a Room Temperature Polariton Laser
J. J. Baumberg, A. V. Kavokin, S. Christopoulos +9
We observe the build up of strong (~50%) spontaneous vector polarisation in emission from a GaN-based polariton laser excited by short optical pulses at room temperature. The Stoke…
