A SiO2 Photonic Platform for the On-Chip Integration of Quantum Emitters — •Florian Böhm1, Niko Nikolay1, Christoph Pyrlik2, Jan Schlegl2, Andreas Thies2, Andreas Wicht2, and Oliver Benson1 — 1AG Nanooptik & IRIS Adlershof, Humboldt-Universität zu Berlin, Germany — 2Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin, Germany
An important prerequisite for future nanophotonic devices is the scalable on-chip integration of single photon emitters.
Here we present the deterministic integration of a single solid-state qubit, the nitrogen-vacancy (NV) center, with a photonic platform consisting exclusively of SiO2 grown thermally on a Si substrate. The platform stands out by its ultra-low fluorescence and the ability to produce various passive structures such as high-Q microresonators and mode-size converters [1].
An numerically optimized structure for the efficient coupling of a dipole emitter to the guided mode was integrated with a preselected NV emitter using an atomic force microscope. We then could demonstrate the on-chip excitation of the quantum emitter as well as the coupling of single photons to the guided mode of the integrated structure [2].
Our approach shows the potential of this platform as a robust nanoscale interface of on-chip photonic structures with solid-state qubits.
