Ua manaʻo ʻia ʻo Silicon-based photonics i kēia manawa ke kahua kiʻi kiʻi hou no nā kamaʻilio i hoʻopili ʻia.Eia nō naʻe, ʻo ka hoʻomohala ʻana i nā modulators optical compact a me ka haʻahaʻa he mea paʻakikī.Ma aneʻi mākou e hōʻike nei i kahi hopena electro-optical nui i nā pūnāwai quantum i hui pū ʻia ʻo Ge/SiGe.Hoʻokumu ʻia kēia hopena hoʻohiki ma ka hopena quantum Stark anomalous ma muli o ka hoʻopaʻa ʻokoʻa ʻana o nā electrons a me nā lua i loko o nā pūnāwai quantum Ge/SiGe.Hiki ke hoʻohana ʻia kēia hanana no ka hoʻomaikaʻi nui ʻana i ka hana o nā modulator māmā i hoʻohālikelike ʻia i nā ala maʻamau i kūkulu ʻia a hiki i kēia manawa i nā kiʻi kiʻi silika.Ua ana mākou i nā hoʻololi ʻana i ka helu kuhikuhi refractive a hiki i ka 2.3 × 10-3 ma ka volta bias o 1.5 V me kahi kūpono modulation kūpono VπLπ o 0.046 Vcm.Hāʻawi kēia hōʻike i ke ala no ka hoʻomohala ʻana i nā modulators kiʻekiʻe kiʻekiʻe e pili ana i nā ʻōnaehana material Ge/SiGe.
