Plasmon–Exciton Interaction in Planar Nanostructures with Quantum Dots

The weak and strong coupling regimes of quantum dots with surface plasmons in a planar nanostructure have been studied theoretically. The rates of nonradiative energy transfer from a quantum dot to a conducting substrate and dispersion dependences of hybrid plasmon–exciton states have been calculated for different values of the parameters of the system under consideration. It has been shown that the energy transfer rates for an interband transition of an electron and for a transition of quantum dots from the exciton to the ground state can significantly exceed the rate of radiative electron–hole recombination. It has been found that, under certain conditions, the Rabi splitting can reach a value of 100 meV or greater.
