Single photon sources are essential for novel hybrid quantum systems and might be used in quantum network architectures, like the quantum repeater. The gain of Quantum Emitters in hexagonal Boron Nitride (hBN) are their promising characteristics such as persisting Fourier limited linewidths from cryogenic [1] up to room temperatures [2]. The suggested reason for this observation is the decoupling from in-plane phonon modes. Here, we present our recent results towards identifying the origin of this mechanical decoupling. They strengthen the assumption that the mechanical decoupling could be caused by out-of-plane emitters. The aim of our measurements is a better understanding of single quantum emitters in hBN, which could allow for implementation of novel hybrid quantum systems and quantum optics experiments at room temperature.
