Nonlinear excitation of polariton cavity modes in ZnO single nanocombs

Mostrar todas las versiones(2)

Tunable second harmonic (SH) polaritons have been efficiently generated in ZnO nanocombs, when the material is excited close to half of the band-gap. The nonlinear signal couples to the nanocavity modes, and, as a result, Fabry-Pérot resonances with high Q factors of about 500 are detected. Due to t...
