Abstract

Quantum wells (QWs) embedded in microcavities (MCs) are now employed to investigate both fundamental and applied aspects of photonics,^1,2 e.g., luminescence enhancement and an analogue of vacuum Rabi splitting³ have been demonstrated in solid-state monolithic structures. The aim of our investigations is a comparison between reflectance and photoluminescence spectra measured on a system consisting of a monolithic half-wavelength MC with two QWs and calculations for the idealized structure. The reflectance spectra are computed by means of the transfer matrix technique⁴ assuming the cavity mode and one luminescence line to be degenerated. Excitonic absorption in the In_0.1Ga_0.9As QWs has been taken into account by classical oscillators leading to a Lorentzian-type resonant term in the complex dielectric function ϵ(ω).
