Descripción
Second harmonic generation and two-photon photoluminescence in CdS quantum dots near metallic nanoparticles are theoretically and experimentally investigated. A control laser fi eld is applied to the hybrid system,which couples with the surface plasmons of the metal nanoparticles. The polarized metal nanoparticles then interact with the quantum dots through dipole–dipole interactions, which enhances the intensity of the second harmonic signal from the quantum dots. The density matrix method is used to numerically simulate the second harmonic signal emitted by the quantum dots. It is found that the enhancement of the second harmonic signal can be switched on and off by changing the control fi eld intensity. Alternatively, the second harmonic signal enhancement can be turned on or off by changing the frequency of the control fi eld. This is an interesting fi nding which can be used to fabricate nonlinear all optical nanoswitching devices from hybrid systems.
