Photoluminescence Excitation Spectroscopy of Single Quantum Emitters in Hexagonal Boron Nitride (h-BN) — •Michael Höse1, Andreas Dietrich1, Rebecca Bernsdorff1, and Alexander Kubanek1,2 — 1Institute for Quantum Optics, Ulm University, D-89081 Ulm, Germany — 2Center for Integrated Quantum Science and Technology (IQst), Ulm University, D-89081 Ulm, Germany
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 (h-BN) revealed promising characteristics including Fourier limited linewidths under resonant excitation [1]. However, the full level structure including detailed characteristics of the phononic sideband lack full understanding.
Here, we present our recent results towards a complete characterization of single quantum emitters in h-BN. Mainly, we use resonant and off-resonant photoluminescence (PLE) spectroscopy to probe the emitter level structure. Our measurements contribute to a better understanding of single quantum emitters in h-BN, thus paving the way for the implementation of novel hybrid quantum systems.
