Abstract
A condensed matter structure includes a substrate having a resonant microcavity formed by reflectors, having a reflectivity R, arranged relative to an optically-active material to form a cavity. The optically-active material has a thickness L, an optical emission line centered at a wavelength &lgr;c, and an optical absorption coefficient &agr;0 at &lgr;c. The magnitude of absorption (&agr;0L) at &lgr;c by the optically-active material is greater than the probability (1−R) that an electromagnetic field having an energy of &lgr;c exits microcavity and thereby results in a strong light-matter interaction between the optically-active material and the electromagnetic field confined in the microcavity.
