Abstract

We investigate lifetime (induced dipole-dipole interaction) of spontaneous parametric four-wave mixing (SP-FWM) and multiorder fluorescence (FL) signals controlled by polarization dressing in a heteronuclear-like molecule system of Pr3+:YSO. The comparisons between a lifetime of SP-FWM and multiorder FL controlled by single dressing, double dressing, and triple dressing polarization have been investigated. It is observed that FLs have a stronger dressing effect than SP-FWM. The polarization dressing is more obvious in the intensity signal in the spectral domain than that in the time domain. Such results have potential applications in quantum communication such as optical information storage, routing, and processing on a photonic chip.
