Fiber-Cavity Enhanced Photon Emission from Defect Centers in hBN — •Manuel Stetter, Patrick Maier, and Alexander Kubanek — Institute for Quantum Optics, University Ulm, Germany

Realization of quantum photonic devices requires coupling single quantum emitters to the mode of optical resonators. We present a hybrid system consisting of a defect center in a hexagonal boron nitride (hBN) nanoparticle and a fiber-based Fabry Pérot cavity. Signal enhancement and strongly narrowed linewidths are achieved, which is owing to cavity funneling.

Keywords: Fiber cavity; hexagonal boron nitride; quantum emitters; 2D-Materials
