Silicon-raws li photonics tam sim no suav tias yog tiam tom ntej photonics platform rau embedded kev sib txuas lus. Txawm li cas los xij, txoj kev loj hlob ntawm compact thiab qis zog optical modulators tseem yog ib qho kev sib tw. Ntawm no peb tshaj tawm cov txiaj ntsig zoo ntawm electro-optical hauv Ge / SiGe txuas quantum qhov dej. Qhov kev cog lus zoo no yog ua raws li qhov tsis zoo ntawm quantum Stark nyhuv vim yog qhov sib cais ntawm cov hluav taws xob thiab qhov hauv qhov sib txuas Ge / SiGe quantum qhov dej. Qhov tshwm sim no tuaj yeem siv los txhim kho kev ua haujlwm ntawm lub teeb pom kev zoo piv rau cov qauv kev tsim tawm kom deb li deb hauv silicon photonics. Peb tau ntsuas cov kev hloov pauv hauv qhov ntsuas qhov taw qhia txog li 2.3 × 10-3 ntawm qhov tsis sib haum xeeb ntawm 1.5 V nrog rau kev hloov pauv kev ua haujlwm zoo VπLπ ntawm 0.046 Vcm. Qhov kev ua qauv qhia no ua rau txoj hauv kev rau kev txhim kho cov qib high-speed modulators raws li Ge / SiGe cov khoom siv.
