The compact sensor device features a side length of 10\u2009mm and includes a small HPHT diamond slab, light\u2010emitting diode (LED) for excitation, and integrated photodiodes. A microwave\u2010free approach is used. With the device, DC sensitivity to magnetic fields of 49\u2009nA\u2009mT<jats:sup>\u22121<\/jats:sup> in the range of 5\u201350\u2009mT is achieved. The sensor device is also capable of detecting very small magnetic fields: Magnetic field dependencies at very low flux densities in the \u03bcT range (zero\u2010magnetic field) show a characteristic fluorescence behavior revealing a sensitivity of 4.8\u2009pA\u2009\u03bcT<jats:sup>\u22121<\/jats:sup>. Additionally, a ray\u2010tracing model is applied, to identify loss mechanisms in the setup. Using this device, an ultracompact, reliable, and industry\u2010ready package is made available for sensor developments in industry and academia.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pssa.202200338","type":"journal-article","created":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T03:28:27Z","timestamp":1665199707000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Compact All\u2010Optical Quantum Sensor Device Based on Nitrogen Vacancy Centers in Diamond"],"prefix":"10.1002","volume":"220","author":[{"ORCID":"http:\/\/orcid.org\/0000-0003-2943-7751","authenticated-orcid":false,"given":"Mario","family":"B\u00e4hr","sequence":"first","affiliation":[{"name":"CiS Forschungsinstitut f\u00fcr Mikrosensorik GmbH Konrad-Zuse-Str. 14 99099 Erfurt Germany"},{"name":"Faculty of Physics and Earth Sciences Applied Quantum Systems (AQS) Leipzig University Linn\u00e9str. 5 04103 Leipzig Germany"}]},{"given":"Martin","family":"Jahn","sequence":"additional","affiliation":[{"name":"CiS Forschungsinstitut f\u00fcr Mikrosensorik GmbH Konrad-Zuse-Str. 14 99099 Erfurt Germany"}]},{"given":"Christoph","family":"Heinze","sequence":"additional","affiliation":[{"name":"CiS Forschungsinstitut f\u00fcr Mikrosensorik GmbH Konrad-Zuse-Str. 14 99099 Erfurt Germany"}]},{"given":"Kristin","family":"Neckermann","sequence":"additional","affiliation":[{"name":"CiS Forschungsinstitut f\u00fcr Mikrosensorik GmbH Konrad-Zuse-Str. 14 99099 Erfurt Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-6711-7367","authenticated-orcid":false,"given":"Jan","family":"Meijer","sequence":"additional","affiliation":[{"name":"Faculty of Physics and Earth Sciences Applied Quantum Systems (AQS) Leipzig University Linn\u00e9str. 5 04103 Leipzig Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-5653-312X","authenticated-orcid":false,"given":"Thomas","family":"Ortlepp","sequence":"additional","affiliation":[{"name":"CiS Forschungsinstitut f\u00fcr Mikrosensorik GmbH Konrad-Zuse-Str. 14 99099 Erfurt Germany"}]}],"member":"311","published-online":{"date-parts":[[2022,12,14]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1088\/0034-4885\/77\/5\/056503"},{"key":"e_1_2_9_3_1","
