Abstract

Optical hybrid communication is one of the key fields of quantum communications,where scientists are focusing to integrate classical and quantum system as single hybridsystem. In this regard, we realized optical hybrid switch using second-order fluorescence(FL) and spontaneous parametric four-wave mixing (SPFWM). The hybrid signal containsStokes and the FL signal which can be distinguished using power of incident beam. Inaddition, we investigate the resonant and off-resonant excitation spectrum of negativelycharged Nitrogen-vacancy (NV⁻) center in diamond. The hybrid switch is realized by resultsobtained in time domain and intensity noise correlation. The optical hybrid switch can becontrolled by power of incident beams. The hybrid index and temporal width contrast of thehybrid switch are about 4 and 90%, respectively.
