A theory of burning spectral holes in an inhomogeneously broadened light absorption profile of quantum dots embedded in a dielectric matrix has been developed. The emphasis was on the possibility of using hole-burning spectroscopy to study the interaction of the electron subsystem of quantum dots with acoustic phonons. An analytical expression describing the shape of differential hole-burning spectra near the fundamental absorption edge for the cases of strong and weak confinement is obtained. The conditions under which the hole-burning spectra are most similar to the absorption spectra of a single quantum dot are determined.
