From single particle to superfuid excitations in a dissipative polariton gas
Verena Kohnle, Yoan Léger, Michiel Wouters +3
Using angle-resolved heterodyne four-wave-mixing technique, we probe the low momentum excitation spectrum of a coherent polariton gas. The experimental results are well captured by…
Spin-to-Orbital Angular Momentum Conversion in Semiconductor Microcavities
F. Manni, K. G. Lagoudakis, T. K. Paraïso +7
We experimentally demonstrate a technique for the generation of optical beams carrying orbital angular momentum using a planar semiconductor microcavity. Despite being isotropic sy…
Selective photoexcitation of exciton-polariton vortices
Gaël Nardin, Konstantinos G. Lagoudakis, Barbara Pietka +3
We resonantly excite exciton-polariton states confined in cylindrical traps. Using a homodyne detection setup, we are able to image the phase and amplitude of the confined polarito…
Theoretical derivation of the bi- and tri-molecular trion formation coefficients
J. Berney, M. T. Portella-Oberli, B. Deveaud-Plédran
A theoretical investigation of the trion formation process from free carriers in a single GaAs/Al_{1-x}Ga_{x}As quantum well is presented. The mechanism for the formation process i…
