Silicon-based photonics parizvino inoonekwa seyanotevera chizvarwa photonics chikuva cheyakamisikidzwa kutaurirana.Nekudaro, kuvandudzwa kwe compact uye yakaderera simba optical modulators inoramba iri dambudziko.Pano tinoshuma hofori ye electro-optical effect muGe/SiGe yakasanganiswa quantum matsime.Iyi inovimbisa mhedzisiro yakavakirwa pane isinganzwisisike quantum Stark mhedzisiro nekuda kwekuvharirwa kwakasiyana kwemaerekitironi nemakomba mumatsime eGe/SiGe quantum akabatanidzwa.Ichi chiitiko chinogona kushandiswa kuvandudza zvakanyanya mashandiro emwenje modulators zvichienzaniswa neyakajairwa nzira dzakagadzirwa kusvika parizvino musilicon photonics.Takayera shanduko mune refractive index kusvika 2.3 × 10-3 pa bias voltage ye 1.5 V ine inoenderana modulation inoshanda VπLπ ye0.046 Vcm.Ichi chiratidziro chinovhura nzira yekuvandudzwa kweanoshanda-yakakwira-kumhanya chikamu modulators yakavakirwa paGe/SiGe zvinhu masisitimu.
