Ama-photonics asuselwa ku-silicon njengamanje athathwa njengenkundla yezithombe zesizukulwane esilandelayo sokuxhumana okushunyekiwe.Kodwa-ke, ukuthuthukiswa kwama-compact optical modulators anamandla aphansi kuseyinselelo.Lapha sibika umphumela omkhulu we-electro-optical kumithombo ye-Ge/SiGe ehlanganiswe ne-quantum.Lo mphumela othembisayo usekelwe kumphumela omangalisayo we-quantum Stark ngenxa yokuvalelwa okuhlukile kwama-electron nezimbobo emithonjeni ye-quantum ye-Ge/SiGe ehlanganisiwe.Lesi simo singasetshenziselwa ukuthuthukisa kakhulu ukusebenza kwamamoduli okukhanya uma kuqhathaniswa nezindlela ezijwayelekile ezithuthukiswe kuze kube manje kuma-silicon photonics.Silinganise izinguquko kunkomba ye-refractive kufika ku-2.3 × 10-3 ku-voltage echemile engu-1.5 V ngokusebenza kahle kokuguquguquka kwe-VπLπ ka-0.046 Vcm.Lokhu kuboniswa kuvula indlela yokuthuthukiswa kwamamoduli wesigaba sesivinini esiphezulu asuselwe ezinhlelweni zezinto ezibonakalayo ze-Ge/SiGe.
