Effects of dissipation and mode broadening in emission spectra of optical cavities and semiconductor microcavities - art. no. 053806

Line-broadening effects in the coupled mode spectrum of optical cavities an d microcavities are included explicitly by (i) the interaction of the elect romagnetic mode with a continuum of electromagnetic modes and (ii) the coup ling of the electronic excitations to a dissipative source. The effects of interaction with an electromagnetic continuum are treated within a Fano mod el, and the electronic excitations are represented by harmonic oscillators. The coupled mode frequencies and their emission spectra are given explicit ly in terms of the parameters of these line-broadening mechanisms, with par ticular attention given to expressions for semiconductor microcavities.
