Vatsvakurudzi vePenn State University muUnited States vakati munguva pfupi, semiconductor core fiber pachayo inogona kukwanisa kudhura "electrical-optical-electrical" kutendeuka pasina kuvimba nemagetsi-optical (electronic-optical) converters, uye inodhura optical- magetsi ekushandura pamagumo ekugamuchira.

Ichi chitsva chinogadzirwa ndechekubatanidza imwechete crystal silicon core mugirazi capillary ine mukati dhayamita ye1.7 microns, uye kusimbisa nekusimbisa pamativi ese maviri kuti igadzire imwe crystal silicon, nekudaro ichibatanidza isingadhuri imwe crystal silicon germanium uye imwechete crystal silicon kumigumo yese. .Tsvakurudzo iyi yakaitwa pamwe chete nemapurofesa Venkatraman Gopalan naJohn Badding muDhipatimendi reZvinhu Sainzi neUinjiniya paPenn State University, uye mudzidzi wechiremba Xiaoyu Ji.

Isai amorphous silicon core mugirazi capillary ine dhayamita yemukati ye1.7 microns.

Iyo yakapfava optical fiber inoshandiswa nhasi inogona chete kuburitsa mafotoni pamwe negirazi chubhu yakavharwa neyakapfava polymer coating.Chiratidzo chakanakisa chinochengetwa mufiber optical nekuratidzira kubva pagirazi kuenda kupolymer, saka panenge pasina kurasikirwa kwechiratidzo panguva yekufambisa kure-kure.Nehurombo, data yese inofambiswa kubva pakombuta inoda kushandiswa kweinodhura electro-optical conversion modules pakupera kwekutumira.

Saizvozvo, iyo inogamuchira ikombiyuta inoda inodhura mafotoelectric converters pamagumo ekugamuchira.Kuti usimbise chiratidzo, iyo yekupedzisira-refu chinhambwe pakati pemaguta akasiyana inoda "inodzokorora" kuita yakanyanya kujeka-yemagetsi kutendeuka, wobva wakudza maerekitironi, wobva wapfuura nepamusoro-soro electro-optical converter kuti usiye chiratidzo chemaziso. pfuura kune inotevera Iyo relay inozosvika kwainoenda.

Vatsvagiri vePenn State University vanotarisira kugadzira mafiber optical akazadzwa neakangwara semiconductors, achivapa kugona kuita magetsi-optical-electrical kutendeuka ivo pachavo.Parizvino, boka rekutsvakurudza harisati rasvika pachinangwa charo, asi rakabudirira kubatanidza zvinhu zvose zvinodiwa mu semiconductor optical fiber uye yakaratidza kuti inogona kutumira photons nema electrons panguva imwe chete.Tevere, ivo vanofanirwa kuenzanisa imwe crystal silicon pamativi ese efiber optical kuita inodiwa yemagetsi-yemagetsi uye yemagetsi-optical kutendeuka munguva chaiyo.

Badding airatidza kugona kwekushandisa silicon-yakazadzwa fiber muna 2006, uye Ji akabva ashandisa lasers kubatanidza yakakwirira-kuchena imwe crystal silicon germanium nemagirazi capillaries muongororo yake yezvidzidzo zvechiremba.Mhedzisiro yacho ndeye smart monosilicon chisimbiso chakareba kakapetwa kaviri, chinoshandura Badding's yepamusoro-soro yepakutanga prototype kuita chinhu chinotengeswa.

Xiaoyu Ji, mumiriri wePhD muDhipatimendi reZvishandiso Sayenzi paPenn State University, anoita bvunzo dzekristallisation paArgonne National Laboratory.

Iyi yekupedzisira-idiki single crystal silicon musimboti zvakare inobvumira Ji kushandisa laser scanner kunyungudutsa uye kunatsa chimiro chekristaro chiri pakati peiyo girazi patembiricha ye750-900 madhigirii Fahrenheit, nekudaro kudzivirira kusvibiswa kwesilicon kwegirazi.

Naizvozvo, zvakatora makore anopfuura gumi kubva pakuedza kwekutanga kwaBadding kubatanidza smart semiconductors uye nyore optical fibers ine yakafanana optical-electrical fiber.

Tevere, vaongorori vanozotanga kukwirisa (kuitira kuita kuti iyo yakangwara faibha isvike kumhanya kwekutapurirana uye hunhu hunofananidzwa nefiber iri nyore), uye gadzira iyo silicon germanium yezvishandiso zvinoshanda, kusanganisira endoscopes, imaging uye fiber lasers.
