Bafuputsi Univesithing ea Penn State e United States ba boletse hore haufinyane, semiconductor core fiber ka boeona e ka khona ho etsa phetoho e theko e boima ea "electrical-optical-electrical" ntle le ho itšetleha ka li-converter tsa motlakase-optical (electron-optical), le optical e theko e boima- li-converter tsa elektroniki qetellong ea ho amohela.

Tlhahiso ena e ncha ke ho kopanya motsoako o le mong oa kristale silicon ka har'a capillary ea khalase e nang le bophara bo ka hare ba li-micron tse 1.7, le ho tiisa le ho tiisa lipheletsong tse peli ho etsa silicon e le 'ngoe ea kristale, kahoo e kopanya kristale e le' ngoe ea silicon germanium e theko e tlaase le silicon e le 'ngoe ea kristale ka mahlakoreng ka bobeli. .Patlisiso ena e entsoe ka kopanelo ke baprofesa Venkatraman Gopalan le John Badding Lefapheng la Mahlale a Materials le Boenjiniere Univesithing ea Penn State, le seithuti sa bongaka Xiaoyu Ji.

Kenyelletsa mokokotlo oa silicon oa amorphous ka har'a capillary ea khalase e nang le bophara bo ka hare ba 1.7 microns.

Fiber e bonolo ea optical e sebelisoang kajeno e ka ntša feela li-photon haufi le tube ea khalase e koahetsoeng ka seaparo se bonolo sa polymer.Letšoao le molemo ka ho fetisisa le bolokiloe ka har'a fiber ea optical ka ho bonahatsa ho tloha ka khalase ho ea ho polymer, kahoo ho na le hoo e ka bang ha ho na tahlehelo ea matšoao nakong ea phetisetso ea nako e telele.Ka bomalimabe, lintlha tsohle tse fetisitsoeng ho tloha khomphuteng li hloka tšebeliso ea li-module tsa phetoho ea electro-optical e theko e boima qetellong ea phetisetso.

Ka mokhoa o ts'oanang, moamoheli ke komporo e hlokang li-converter tsa photoelectric tse theko e boima qetellong ea ho amohela.E le ho matlafatsa lets'oao, sebaka se selelele sa nako e telele pakeng tsa litoropo tse fapaneng se hloka "pheta" ho etsa phetoho e tebileng ea optical-electrical, ebe o holisa lielektrone, ebe o feta ka har'a sesebelisoa sa super electro-optical ho lumella lets'oao la optical. Fetisetsa ho e latelang Pheliso e qetellang e fihlile moo e eang teng.

Bafuputsi ba Univesithi ea Penn State ba na le tšepo ea ho hlahisa likhoele tsa optical tse tletseng li-semiconductors tse bohlale, tse ba fang bokhoni ba ho etsa phetoho ea motlakase-optical-electrical ka bobona.Hona joale, sehlopha sa lipatlisiso ha se e-s'o finyelle sepheo sa sona, empa se atlehile ho kopanya lisebelisoa tsohle tse hlokahalang ka semiconductor optical fiber 'me se paka hore se ka fetisetsa lifoto le li-electrone ka nako e le' ngoe.Ka mor'a moo, ba hloka ho etsa mohlala oa silicon e le 'ngoe ea kristale lipheletsong tse peli tsa fiber ea optical ho etsa phetoho e hlokahalang ea optical-electric le motlakase-optical ka nako ea sebele.

Badding o ile a bonts'a monyetla oa ho sebelisa likhoele tse tlatsitsoeng ka silicon ka 2006, mme Ji o ile a sebelisa lasers ho kopanya kristale e le 'ngoe ea silicon germanium e hloekileng le li-capillaries tsa khalase lipatlisisong tsa hae tsa thuto ea bongaka.Sephetho ke tiiso e bohlale ea monosilicon e bolelele ba makhetlo a 2,000, e fetolang mohlala oa pele oa boemo bo holimo oa Badding hore e be thepa e ka rekisoang.

Xiaoyu Ji, mokhethoa oa PhD Lefapheng la Mahlale a Materials Univesithing ea Penn State, o etsa liteko tsa crystallization Laboratory ea Naha ea Argonne.

Mokotlana ona oa kristale o le mong o monyane haholo o boetse o lumella Ji ho sebelisa sekenara sa laser ho qhibiliha le ho hloekisa sebopeho sa kristale bohareng ba khalase ka mocheso oa likhato tse 750-900 tsa Fahrenheit, ka hona ho qoba tšilafalo ea silicon ea khalase.

Ka hona, ho nkile lilemo tse fetang 10 ho tloha tekong ea pele ea Badding ea ho kopanya li-semiconductors tse bohlale le likhoele tse bonolo tsa optical tse nang le fiber e tšoanang ea optical-electrical.

Ka mor'a moo, bafuputsi ba tla qala ho ntlafatsa (e le ho etsa hore fiber e bohlale e fihle lebelo la phetisetso le boleng bo bapisoang le fiber e bonolo), le mohlala oa silicon germanium bakeng sa lisebelisoa tse sebetsang, ho akarelletsa le endoscopes, imaging le fiber lasers.
