The appearance of Fano resonances in the fine structure of the optical absorption spectra is predicted for all semiconductor quantum structures with one or two degrees of freedom. The resonances are explained by Coulomb coupling of the bound and scattering states of an exciton series belonging to different subband pairs but occuring at the same photon energy. To demonstrate this effect, two examples, the quantum well and the quantum-well wire, are treated numerically. The optical spectra show Fano resonances.
