Nonlinear relaxation of 0-dimension-trapped microcavity polaritons
Ounsi El Daif, Gael Nardin, Taofiq K. Paraiso +6
We study the emission properties of confined polariton states in shallow zero-dimensional traps under non-resonant excitation. We evidence several relaxation regimes. For slightly…
Absorption enhancement in amorphous silicon photonic crystals for thin film photovoltaic solar cells
Ounsi El Daif, Emmanuel Drouard, Yeonsang Park +8
We report on very high enhancement of thin layer's absorption through band-engineering of a photonic crystal structure. We realized amorphous silicon (aSi) photonic crystals, where…
Engineering the spatial confinement of exciton-polaritons in semiconductors
Reda Idrissi Kaitouni, Ounsi El Daif, Maxime Richard +8
We demonstrate the spatial confinement of electronic excitations in a solid state system, within novel artificial structures that can be designed having arbitrary dimensionality an…
