{"title":"Fully guided and phase locked Ti:PPLN waveguide squeezing for applications in quantum sensing","abstract":[{"text":"<jats:p>This work reports a fully guided setup for single-mode squeezing on integrated titanium-indiffused periodically poled nonlinear resonators. A continuous-wave laser beam is delivered and the squeezed field is collected by single-mode fibers; up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the usefulness of such a fiber-coupled device, we applied the generated squeezed light in a fiber-based phase sensing experiment, showing a quantum enhancement in the signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of photorefraction on the cavity resonance condition suggests that it causes system instabilities at high powers.</jats:p>","lang":"eng"}],"issue":"11","intvolume":"        48","date_updated":"2023-07-25T10:58:05Z","volume":48,"project":[{"name":"UNIQORN: UNIQORN - Affordable Quantum Communication for Everyone - EU Quantum Flagship Project","_id":"218"}],"department":[{"_id":"230"},{"_id":"623"},{"_id":"288"}],"publication_status":"published","doi":"10.1364/ol.486654","date_created":"2023-07-25T10:35:24Z","publication_identifier":{"issn":["0146-9592","1539-4794"]},"author":[{"first_name":"Renato","full_name":"Domeneguetti, Renato","last_name":"Domeneguetti"},{"last_name":"Stefszky","full_name":"Stefszky, Michael","first_name":"Michael","id":"42777"},{"last_name":"Herrmann","full_name":"Herrmann, Harald","id":"216","first_name":"Harald"},{"last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263","first_name":"Christine"},{"last_name":"Andersen","full_name":"Andersen, Ulrik L.","first_name":"Ulrik L."},{"first_name":"Jonas S.","last_name":"Neergaard-Nielsen","full_name":"Neergaard-Nielsen, Jonas S."},{"first_name":"Tobias","last_name":"Gehring","full_name":"Gehring, Tobias"}],"publication":"Optics Letters","language":[{"iso":"eng"}],"quality_controlled":"1","type":"journal_article","keyword":["Atomic and Molecular Physics","and Optics"],"publisher":"Optica Publishing Group","article_number":"2999","citation":{"short":"R.
