Single Photon Sources with Surface Plasmons

Abstract

Single photon sources play a crucial role in the leading quantum technologies however, there is still no ideal single photon emitter on demand. In this study, we will visit the concept of single photon sources, surface plasmon polaritons (SPPs) and the coupling of surface plasmons with the single photon emitters to discuss the effects on the emission of single photons and its efficiency. First, we will prove the existence of single photon sources from the Mandel Dip experiment and the second order correlation. Then we will study the effects of coupling SPPs with single photon emitters through photon counting. The time elapsed between two consecutive emitted single photonsor the lifetime is our predictor of efficiency. As the results show that when the emitters were coupled, the time decreased for the emission of a photon after the system returned to its de-excitated state.
