Abstract

We report a comprehensive measurement and theoretical interpretation of the damping dispersion of the A exciton polariton in CdS over a wide frequency range. We demonstrate tor the first time, we believe, that the source of the damping is completely different for excitation above or below the transverse exciton frequency.
