PAT in five-guide optical system.
The left column: (a) the minimum value of population distribution at guide 1, Min(P1), versus Ω2 with A = 6.6, ω = 3, Ω1 = 1; (b) the corresponding quasi-energy ε versus Ω2 and (c)the time-averaged population 〈Fj〉 belonging to the zero-energy (dark) Floquet state versus Ω2. The right column: (d) Min(P1) versus A/ω for the 1-photon resonance ω = 3, Ω2 = 2.8, Ω1 = 1; (e) the corresponding quasi-energy ε versus A/ω and (f) the time-averaged population 〈Fj〉 belonging to the zero-energy (dark) Floquet state versus A/ω.
