Single photon sources are crucial building blocks for novel hybrid quantum systems, which will allow for implementing quantum repeaters or other quantum network architectures. Quantum Emitters in hexagonal boron nitride (hBN) revealed promising characteristics such as persisting Fourier limited linewidths from cryogenic [1] up to room temperatures [2]. This observation was attributed to decoupling from in-plane phonon modes. Here, we present our recent results towards identifying the origin of this mechanical decoupling, which could be caused by out-of-plane emitters. Our measurements contribute to a better understanding of single quantum emitters in hBN, thus paving the way for the implementation of novel hybrid quantum systems and quantum optics experiments at room temperature.
