Within the frameworks of the second order perturbation theory the light absorption by free carriers in a parabolic quantum well (QW) is investigated taking into account the scattering by the three-dimensional optical phonons. An analytical expression for the absorption coefficient is obtained taking into the consideration two processes, with initial absorption of a photon and further scattering by optical phonons, and with the initial scattering by the optical phonons and the subsequent absorption of the photon. Frequency characteristics and dependences on the temperature and the width of QW are examined.
