Abstract
A new optical effect, the coherent control of spontaneous secondary emission with the participation of optical phonons in systems with discrete spectra of electronic transitions, is studied theoretically. Analytical formulas are obtained that describe the time-integrated signals of secondary emission excited resonantly by a pair of phase-locked pulses in the homogeneously and inhomogeneously broadened systems of semiconductor quantum dots. It is shown that coherent control is a promising method for measuring the total dephasing rates of a resonance optical transition. A physically justified criterion for discriminating between scattering and luminescence in the secondary emission is found. The role of spectral filtering of the signal in the measurements of phase and energy relaxation parameters is elucidated.
