Hybrid Rossby-shelf modes in a laboratory ocean [PDF]

open access: yes, 2008
Idealized laboratory experiments reveal the existence of forced–dissipative hybrid Rossby-shelf modes. The laboratory ocean consists of a deeper ocean (accommodating basin-scale Rossby modes) and a coastal step shelf (accommodating trapped shelf modes ...

Observation of enhanced spontaneous and stimulated emission of GaAs/AlGaAs nanowire via the Purcell effect

open access: yesAIP Advances, 2015
We experimentally demonstrated enhanced spontaneous and stimulated emission of GaAs/AlGaAs nanowire via the Purcell effect. By integrating the NW and SiO2-Au substrate, the hybridization of the dielectric modes in the NW with surface plasmons on the ...
