We investigate optical bistability (OB) and optical multistability (OM) behaviors in a triply driven five-level atomic system. It is shown that the system has bistable behavior and can be controlled by intensity of applied fields. We find that OB switches to OM via interference induced among the Rabi-split resonance. We consider a superposed one-dimension standing wave, generated by two optical fields, and it is demonstrated that the OB and OM behaviors depend on the position of localized atoms as well as the relative phase of applied fields.

“…Moreover, the double dark resonance has been used for controlling the OB behavior in a fourlevel atomic system [11,12]. Recently, we have reported phase-controlled OB via electromagnetically induced absorption in a four-level double V-type closed-loop system, and it was shown that OB switches to OM via applying a microwave field [13].…”

“…In contrast, EIA is a result of constructive interference due to transfer of coherence in Zeeman-degenerate systems4. Most recent research is concerned with multi-photon coherence processes56789 and is carried out in multilevel atomic systems, including Lambda-, cascade- and N-type systems101112.…”

We investigate tunneling induced nonlinear absorption phenomena in a coupled quantum-dot system. Resonant tunneling causes constructive interference in the nonlinear absorption that leads to an increase of more than an order of magnitude over the maximum absorption in a coupled quantum dot system without tunneling. Resonant tunneling also leads to a narrowing of the linewidth of the absorption peak to a sublinewidth level. Analytical expressions show that the enhanced nonlinear absorption is largely due to the fifth-order nonlinear term. Competition between third- and fifth-order nonlinearities leads to an anomalous dispersion of the total susceptibility.
