Dynamic Fano Resonance of Quasienergy Excitons in Superlattices
Ren-Bao Liu, Bang-fen Zhu
Abstract
The dynamic Fano resonance (DFR) between discrete quasienergy excitons and sidebands of their ionization continua is predicted and investigated in dc- and ac-driven semiconductor superlattices. This DFR, well controlled by the ac field, delocalizes the excitons and opens an intrinsic decay channel in nonlinear four-wave mixing signals.
