Abstract :
Optical absorption spectra due to Fano resonance (FR) of an exciton in a quantum well with an external electric field perpendicular to the layer plane are presented, based on multi-channel scattering calculations incorporating a hole-subband mixing effect. Peak values of the calculated FR spectra exhibit anomalous field-dependent changes. These cannot be accounted for by the commonly-known quantum-confined Stark effect (QCSE) that has been applied exclusively to bound state spectra. This behavior, ascribable to correlation between Fano couplings and the QCSE, is revealed just in high-resolution spectra, otherwise the field-dependence results in nothing but the same as that of the bound-state spectra.
