Bismuth silicon oxide (Bi12SiO20) muaj piezoelectric, electro-optic, elasto-optic thiab photoconductive cov khoom, thiab thiaj li muaj tej daim ntaub ntawv inspatial lub teeb modulators, kab acoustic qeeb, hologram teev cov khoom thiab theem conjugation thiab lwm yam.


BSOshow nws thaum lawv tseem txawv zog lub cev. BSO muaju yog heev npaum photoconductors uas tsaus nti conductivity tsawg tsawg uas tso cai rau lub build-up ntawm loj Diam duab hob chaw-tsub. Tseem muaj zog spectral dependence cov photoconductivity thiab cov electrooptic zog tso cai rau tsim thiab ua tau ntau yam kev kho qhov muag pab kiag li lawm thiab tshuab. BSO siv lead ua los rau spatial lub teeb modulators, dynamic real-time hologram cov ntaubntawv povthawj siv pab kiag li lawm, theem conjugation yoj nws, correlators kho qhov muag thiab kho qhov muag laser tshuab mus kho lus adaptive ntawm lub teeb ultrashort pulses. Hob Diam duab haum kom tau nthuav hab ua ô teeb-lightö yam ntawm cov kho qhov muag xws li modulators kho qhov muag, keyboards thiab lwm yam. Cov Sillenite Oxide nyias-zaj duab xis fabrication siv lead ua lug ntawm cov txheej txheem sib txawv no rau txoj kev sau ntev ntawm cov nrog kho qhov muag, waveguides integrated kho qhov muag pab kiag li lawm. Siv cov waveguide kho qhov muag lug le Sillenites pub rau after yam illumination (feem ntau rau cov dav hlau ntawm waveguide) nyob rau hauv ib chav wide spectral. Cov kuj loj electrooptic thiab Faraday nyhuv uas Sillenite Oxides ua kom lawv pab tau rau optical fiber fais/sib nqus teb sensors.
