In this work, we study the absorption power in a special asymmetric hyperbolic-type when electrons are scattered with longitudinal optical phonons (LO-phonons). The explicit analytic expression for absorption power is obtained using the projection operator technique. Conditions for optically detected electrophonon resonance (ODEPR) are obtained based on the energy conservation law. Computational results show that the absorption power as well as the full width at half maximum (FWHM) of the ODEPR peaks increase with temperature and decrease with the characteristic parameters of the quantum well. Moreover, these results also show the agreement with previous studies in both theoretically and experimentally.
