Example of transmitted intensity versus input intensity curve of a bistable device.
Two nonlinear delta-function barriers.
Transmission coefficient versus wave vector. Dashed curve: linear regime (, ). Solid curve: weakly nonlinear regime (, ).
Transmission coefficient versus wave vector for a strongly nonlinear regime (, ). We observe bistability around the first two resonances.
Magnification of the selected regions around the first three resonances in Fig. 4.
(a) Transmission curves around a single resonance for a linear system with effective opacities and . (b) Stable transmission paths (arrows and solid black curves) followed by the system around a single resonance.
