A study was conducted on an optical conductivity of nine LSCO samples spanning the insulating, superconducting, and metallic region of the phase diagram of this compound. It was observed that, at energies lower than those of any phonon mode, clear features which were stronger than both the phonons and the narrow, hardly detectable Drude term. Hence, such strong features were due to collective excitations of charged systems which extend on many cells.
