(a) A Ag NW couples to a QD. The SP modes are described by and . (b) Energy configuration of the QD. The , , and can be vacuum state, exciton state, and biexciton state of a QD. One can choose tellurium doped CdSe colloidal QD. is much larger than due to the Coulomb repulsion between the two excitons (see Ref. 24), where and are the transition frequencies between and , respectively. As a result, the transition between and coupled by the SP can be ignored.

(a) The transmission (solid line) and reflection (dashed line) spectra for two-level system with the case. (b) The transmission (solid line) and reflection (dashed line) spectra for the cascaded three-level system with (in the unit of ) case. Insets show the energy-level couplings of QD with classic field tuning off (a), and on (b).

FIG. 3.

The reflection (a) and transmission (b) spectra for two-level system case. The reflection (c) and transmission (d) spectra for the cascaded three-level system case with different (in the unit of ). In the calculations, is set as 0.1 (in the unit of ).

FIG. 4.

The reflection (a) and transmission (b) spectra for two-level system case. The reflection (c) and transmission (d) spectra for the cascaded three-level system case with (solid line), 8.7 (dash line), and 20 (dash-dot line). The reflection spectrum shows four, three, and two peaks when , 8.7, and 20, respectively. In the calculations, is set as −0.1 (in the unit of ).
