| 中文摘要 | We investigate the midinfrared generation from difference frequency in self-assembled quantum dots near metal nanoparticles with two-color interband excitations. The generated signal strength is enhanced by several orders of magnitude due to the plasmon-exciton resonance in the nanosuperstructures. The signal enhancement is found to be the result of competition between local electric field enhancement and excitonic lifetime shortening. Therefore, there exists an optimal interparticle distance for the difference-frequency generation. This nanomolecule is proposed to be an excellent candidate for the midinfrared quantum dot laser.
