Abstract
A two-photon absorption resonance is observed when the sum-frequency of two laser pulses equals the creation energy of a biexciton in a single InAs/GaAs semiconductor quantum dot. Resonant excitation of the two-color two-photon transition results in a coherent oscillation that is remarkably similar to a single-color two-photon Rabi oscillation of the crystal-ground to biexciton optical transition. A model explaining the coherent two-photon absorption is presented.
