SiO2 on Si photonic platform with ultra-low intrinsic fluorescence for integrated single photon emitters based on diamond defect centers — •Florian Böhm1, Christoph Pyrlik2, Niko Nikolay1, Jan Schlegel2, Andreas Thies2, Andreas Wicht2, and Oliver Benson1 — 1AG Nanooptik, Humbodt-Universität zu Berlin, Germany — 2Ferdinand-Braun-Institut für Höchstfrequenztechnik, Berlin, Germany
On-chip photonic structures, for example integrated solid-state single photon sources, effectively coupled to a single guided optical mode are one important tool towards future applications in quantum information science [1]. Typically excitation and fluorescence collection from single emitters requires bulky confocal microscopes.
We report on our approach towards an integrated single photon source, consisting of nano-sized quantum emitters (NV centers in diamond), evanescently coupled to photonic structures in SiO2. This novel hybrid system, based on pure, undoped SiO2, exhibits exceptionally low intrinsic fluorescence and allows high reproducibility and diversity in the fabrication of photonic elements e.g. waveguides, mode-size converters, couplers and resonators.
Our results are promising steps towards realizing a fully integrated single photon source. Deterministic [2] coupling of a single quantum emitter to the system could enable simultaneous on-chip excitation and collection, rendering the microscope objective unnecessary.
