Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles.</jats:p>","lang":"eng"}],"date_created":"2023-01-27T13:41:42Z","publisher":"Springer Science and Business Media LLC","title":"Nonlinear down-conversion in a single quantum dot","issue":"1","year":"2022","department":[{"_id":"15"},{"_id":"297"},{"_id":"230"},{"_id":"429"},{"_id":"27"},{"_id":"623"},{"_id":"170"},{"_id":"35"}],"user_id":"16199","_id":"40523","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"TRR 142 - A03: TRR 142 - Subproject A03","_id":"60"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"article_number":"1387","type":"journal_article","status":"public","volume":13,"author":[{"first_name":"B.","last_name":"Jonas","full_name":"Jonas, B."},{"first_name":"Dirk Florian","id":"10904","full_name":"Heinze, Dirk Florian","last_name":"Heinze"},{"first_name":"E.","last_name":"Schöll","full_name":"Schöll, E."},{"first_name":"P.","full_name":"Kallert, P.","last_name":"Kallert"},{"full_name":"Langer, T.","last_name":"Langer","first_name":"T."},{"first_name":"S.","last_name":"Krehs","full_name":"Krehs, S."},{"full_name":"Widhalm, A.","last_name":"Widhalm","first_name":"A."},{"full_name":"Jöns, Klaus","id":"85353","last_name":"Jöns","first_name":"Klaus"},{"first_name":"Dirk","last_name":"Reuter","full_name":"Reuter, Dirk","id":"37763"},{"first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271","full_name":"Schumacher, Stefan"},{"first_name":"Artur","full_name":"Zrenner, Artur","id":"606","last_name":"Zrenner","orcid":"0000-0002-5190-0944"}],"date_updated":"2023-04-20T15:18:31Z","doi":"10.1038/s41467-022-28993-3","publication_identifier":{"issn":["2041-1723"]},"publication_status":"published","intvolume":"        13","citation":{"chicago":"Jonas, B., Dirk Florian Heinze, E.

Usually, the photon is emitted from a single-exciton ground state.\r\nPolarization of the photon and time of emission are either probabilistic or pre-determined by\r\nelectronic properties of the system. Here, we study the direct two-photon emission from the\r\nbiexciton. The two-photon emission is enabled by a laser pulse driving the system into a\r\nvirtual state inside the band gap. From this intermediate state, the single photon of interest\r\nis then spontaneously emitted. We show that emission through this higher-order\r\ntransition provides a versatile approach to generate a single photon. Through the driving\r\nlaser pulse, polarization state, frequency and emission time of the photon can be controlled\r\non-the-fly."}],"language":[{"iso":"eng"}]}]
