Ultra-low threshold polariton lasing in photonic crystal cavities
Stefano Azzini, Dario Gerace, Matteo Galli +5
The authors show clear experimental evidence of lasing of exciton polaritons confined in L3 photonic crystal cavities. The samples are based on an InP membrane in air containing fi…
Exciton polaritons in two-dimensional photonic crystals
Daniele Bajoni, Dario Gerace, Matteo Galli +7
Experimental evidence of strong coupling between excitons confined in a quantum well and the photonic modes of a two-dimensional dielectric lattice is reported. Both resonant scatt…
Optical bistability in a GaAs based polariton diode
Daniele Bajoni. Elizaveta Semenova, Aristide Lemaître, Sophie Bouchoule +5
We report on a new type of optical nonlinearity in a polariton p-i-n microcavity. Abrupt switching between the strong and weak coupling regime is induced by controlling the electri…
