Ofufuza pa yunivesite ya Penn State ku United States adanena kuti posachedwa, semiconductor core fiber yokha ikhoza kutembenuza mtengo wa "electrical-optical-electrical" popanda kudalira magetsi-optical (electron-optical) converters, ndi optical okwera mtengo- otembenuza zamagetsi pamapeto olandira.

Kupangidwa kwatsopano kumeneku ndikuphatikiza pakatikati pa kristalo wa silicon mu capillary yagalasi yokhala ndi mainchesi 1.7, ndikulimbitsa ndikusindikiza mbali zonse ziwiri kuti apange silikoni imodzi ya crystal, potero kuphatikiza mtengo wa crystal silicon germanium ndi crystal silikoni imodzi kumapeto onse awiri. .Kafukufukuyu adachitidwa limodzi ndi mapulofesa Venkatraman Gopalan ndi John Badding mu dipatimenti ya Materials Science and Engineering ku Penn State University, ndi wophunzira udokotala Xiaoyu Ji.

Phatikizani pakati pa silicon ya amorphous mu capillary yagalasi yokhala ndi mainchesi 1.7 mkati.

Chingwe chosavuta cha kuwala chomwe chimagwiritsidwa ntchito masiku ano chimatha kutulutsa mafotoni motsatira chubu lagalasi lophimbidwa ndi zokutira zofewa za polima.Chizindikiro chabwino kwambiri chimasungidwa mu fiber optical powonetsa kuchokera pagalasi kupita ku polima, kotero palibe pafupifupi kutayika kwa chizindikiro panthawi yotumiza mtunda wautali.Tsoka ilo, deta yonse yotumizidwa kuchokera ku kompyuta imafuna kugwiritsa ntchito ma module okwera mtengo a electro-optical conversion kumapeto kwa kutumiza.

Mofananamo, wolandila ndi kompyuta yomwe imafuna otembenuza ma photoelectric okwera mtengo pamapeto olandira.Kuti mulimbikitse chizindikirocho, mtunda wautali kwambiri pakati pa mizinda yosiyanasiyana umafunikira "wobwereza" kuti atembenuzire kwambiri kuwala kwamagetsi, kenako kukulitsa ma electron, ndiyeno kudutsa mu super electro-optical converter kuti alole chizindikiro cha kuwala. kupita ku yotsatira Kupatsirana kumafika komwe kukupita.

Ochita kafukufuku ku yunivesite ya Penn State akuyembekeza kupanga ulusi wowoneka bwino wodzazidwa ndi ma semiconductors anzeru, kuwapatsa luso lopanga kutembenuka kwamagetsi pawokha.Pakalipano, gulu lofufuza silinakwaniritsidwebe cholinga chake, koma lagwirizanitsa bwino zipangizo zonse zomwe zimafunikira mu semiconductor optical fiber ndipo zatsimikizira kuti zimatha kutumiza ma photon ndi ma electron pa nthawi yomweyo.Kenako, amayenera kupanga mawonekedwe a crystal silicon pamakona onse a fiber optical kuti apange kutembenuka kofunikira kwamagetsi ndi magetsi mu nthawi yeniyeni.

Badding adawonetsa kuthekera kogwiritsa ntchito ulusi wodzazidwa ndi silicon mu 2006, ndipo Ji adagwiritsa ntchito ma lasers kuphatikiza ma crystal silicon germanium apamwamba kwambiri ndi ma capillaries agalasi pakufufuza kwake kwa udokotala.Zotsatira zake ndi chosindikizira chanzeru cha monosilicon chomwe chimakhala chotalikirapo nthawi 2,000, chomwe chimatembenuza chithunzithunzi choyambirira cha Badding kukhala chinthu chogulitsira malonda.

Xiaoyu Ji, wophunzira wa PhD mu Dipatimenti ya Materials Science ku Penn State University, amayesa crystallization ku Argonne National Laboratory

Choyimira chaching'ono chaching'ono ichi cha crystal silicon chimalolanso kuti Ji agwiritse ntchito makina ojambulira laser kuti asungunuke ndikuyeretsa mawonekedwe a kristalo pakatikati pa galasi lapakati pa kutentha kwa 750-900 degrees Fahrenheit, potero amapewa kuipitsidwa ndi galasi.

Chifukwa chake, zatenga zaka zopitilira 10 kuchokera pomwe Badding adayesa kuphatikizira ma semiconductors anzeru ndi ulusi wosavuta wamagetsi wokhala ndi ulusi womwewo wamagetsi.

Kenako, ofufuzawo ayamba kukhathamiritsa (kuti apangitse kuti ulusi wanzeru ufike pa liwiro lotumizira komanso mtundu wofananira ndi ulusi wosavuta), ndikuwonetsa silicon germanium kuti agwiritse ntchito, kuphatikiza ma endoscopes, imaging ndi fiber lasers.
