Abstract

Optical properties of a 3/2 λ cavity with embedded a rectangular dielectric grating and a quantum well at the anti-nodes of the electromagnetic field are computed in semi-classical framework. For the reciprocal lattice vector of the grating ( G=2 π/ 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 cavity, can be studied by linear optical spectroscopy. The Rabi energy and radiative recombination time of the cavity are computed, and the role of disorder is briefly discussed.
