Ingaruka nini ya Electro-Optical muri Ge / SiGe Ihujwe na Quantum Iriba

Amafoto ashingiye kuri silicon kuri ubu afatwa nkibisekuru bizaza bya fotonike yo gutumanaho gushizwemo. Ariko, iterambere ryimyitozo ngororamubiri ntoya kandi ntoya iracyari ingorabahizi. Hano twatangaje ingaruka nini ya electro-optique muri Ge / SiGe ifatanije na kwantum. Izi ngaruka zitanga ikizere zishingiye kuri anomalous kwant Stark ingaruka bitewe no gufunga gutandukanya electroni nu mwobo mu mariba ya Ge / SiGe. Iyi phenomenon irashobora gukoreshwa mugutezimbere imikorere yimikorere yumucyo ugereranije nuburyo busanzwe bwateye imbere kugeza ubu muri fotonike ya silicon. Twapimye impinduka mubyerekezo byangiritse bigera kuri 2,3 × 10-3 kuri bias ya voltage ya 1.5 V hamwe nuburyo bwiza bwo guhindura VπLπ ya 0.046 Vcm. Iyi myiyerekano itanga inzira yiterambere ryimikorere yihuta yihuta ya modulator ishingiye kuri sisitemu yibikoresho bya Ge / SiGe.
