S. Pau et al., PHONON POLARITON INTERACTION IN A MICROCAVITY, Nuovo cimento della Societa italiana di fisica. D, Condensed matter,atomic, molecular and chemical physics, biophysics, 17(11-12), 1995, pp. 1657-1662
The linewidth of the microcavity exciton polariton is studied by on-re
sonant and off-resonant photoluminescences. The two main contributions
to the linewidth are caused by radiative loss and phonon scattering.
The oscillator strength is found to be unmodified by the exciton-phono
n coupling. Comparison is made between theory and experiment.
