Optically active color centers in hexagonal boron nitride are promising cadidates as single photon sources. Therefore, they have been extensively studied in recent years [1]. Their atomic origin is still unknown, so the experiments presented in this paper shed light on the underlying level structure. We will show that two spectra differing in their polarization contribute to the fluorescence of the observed single photon emitter. Based on these results, we then present polarization-sensitive photon correlation measurements [2] and compare them to a multilevel rate equation model. As a future perspective, we discuss the potential of this theoretical and experimental framework to further explore the electronic level structure of single photon centers in hexagonal boron nitride.
