Abstract
Optical properties of a 3/2 l cavity with embedded a rectangular dielectric grating and a quantum well at the anti-nodes of the electromagnetic field are computed in a semi-classical framework. For the reciprocal lattice vector of the grating G=2p/d (where d is the periodicity) close to the characteristic light wave vector, the diffracted waves (with in-plane wavevector k//= G) propagate into the cavity, and, therefore the density of states of radiative modes, leaky in the planar semiconductor microcavity, can be studied by linear optical spectroscopy. The Rabi energy, and the radiative recombination time of the cavity are computed, and the role of disorder is briefly discussed .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
