Abaphandi kwiYunivesithi yasePenn State eUnited States bathi kungekudala, i-semiconductor core fiber ngokwayo ingakwazi ukwenza uguqulo olubiza kakhulu "i-electrical-optical-electrical" ngaphandle kokuthembela kwi-electric-optical (electron-optical) converters, kunye ne-optical ebiza kakhulu- abaguquli be-elektroniki ekupheleni kokufumana.

Olu luqalo lutsha kukudibanisa icrystal silicon engundoqo kwiglasi yecapillary enobubanzi obungaphakathi obuyi-1.7 microns, kwaye iqinise kwaye itywine kuzo zombini iziphelo ukwenza icrystal silicon enye, ngaloo ndlela kudityaniswa ngexabiso eliphantsi elinye lecrystal silicon germanium kunye necrystal silicon eyodwa kuzo zombini iziphelo. . Olu phando lwenziwe ngokudibeneyo ngoonjingalwazi uVenkatraman Gopalan kunye noJohn Badding kwiSebe lezeNzululwazi kunye nobuNjineli kwiYunivesithi yasePenn State, kunye nomfundi ogqirha uXiaoyu Ji.

Fakela i-silicon engundoqo ye-amorphous kwi-capillary yeglasi kunye ne-diameter yangaphakathi ye-1.7 microns

Ifiber elula esetyenziswayo namhlanje inokukhupha kuphela iifotoni ecaleni kwetyhubhu yeglasi egqunywe ngengubo ethambileyo yepolymer. Isibonakaliso esihle kakhulu sigcinwe kwi-fiber optical ngokubonakalisa ukusuka kwiglasi ukuya kwi-polymer, ngoko akukho phantse ilahleko yesignali ngexesha lokuhanjiswa komgama omde. Ngelishwa, yonke idatha ethunyelwa kwikhompyutheni ifuna ukusetyenziswa kweemodyuli zokuguqulwa kwe-electro-optical ezibizayo ekupheleni kokudlulisa.

Ngokufanayo, umamkeli yikhompyuter efuna iiconverter zefoto zombane ezibizayo ekupheleni kokufumana. Ukomeleza umqondiso, umgama omde phakathi kwezixeko ezahlukeneyo ufuna "uphinda-phinda" ukwenza uguqulo olubukhali ngakumbi lombane, emva koko ukhulise ii-electron, emva koko udlule kwisiguquli se-electro-optical super ukuvumela uphawu lokukhanya. dlulela kwelandelayo I-relay ekugqibeleni ifike kwindawo yayo.

Abaphandi kwiYunivesithi yasePenn State banethemba lokuphuhlisa imicu ye-optical egcwele i-semiconductors ehlakaniphile, ebanika amandla okwenza ukuguqulwa kombane-optical-electrical ngokwabo. Okwangoku, iqela lophando alikafiki kwiinjongo zalo, kodwa lidibanise ngempumelelo zonke izinto ezifunekayo kwi-fiber optical semiconductor kwaye yabonisa ukuba inokudlulisa iifoto kunye nee-electron ngexesha elifanayo. Emva koko, kufuneka benze ipateni ye-crystal silicon eyodwa kuzo zombini iziphelo zefiber optical ukwenza uguqulo oluyimfuneko lwe-optical-electric kunye nombane-optical ngexesha langempela.

U-Badding ubonise ukubanakho ukusebenzisa iintsinga ezizaliswe yisilicon ngo-2006, kwaye uJi emva koko wasebenzisa iilaser ukudibanisa icrystal silicon germanium ephezulu ecocekileyo enye kunye neecapillaries zeglasi kuphando lwakhe lobugqirha. Isiphumo sisitywina se-monosilicon esilumkileyo esiphindwe ngama-2,000 ubude, esiguqula iprototype ye-Badding ephezulu yobuchule boqobo ibe yinto enorhwebo.

U-Xiaoyu Ji, umviwa we-PhD kwiSebe leSayensi yeMathiriyeli kwiYunivesithi yasePenn State, uqhuba iimvavanyo zecrystallization kwiLebhu yeSizwe yaseArgonne.

Lo mbindi we-crystal crystal core uphinda uvumele uJi ukuba asebenzise iskena selaser ukuze anyibilike kwaye acokise ulwakhiwo lwekristale embindini wombindi weglasi kubushushu obuyi-750-900 degrees Fahrenheit, ngaloo ndlela kuthintela ukungcoliseka kwesilicon yeglasi.

Ke ngoko, kuthathe iminyaka engaphezu kwe-10 ukusuka kumzamo wokuqala we-Badding wokudibanisa i-semiconductors ehlakaniphile kunye neefiber ezilula zamehlo ezinefiber efanayo yombane.

Emva koko, abaphandi baya kuqalisa ukulungelelanisa (ukwenzela ukwenza i-fiber ehlakaniphile ifikelele kwisantya sothumelo kunye nomgangatho ohambelana nefiber elula), kwaye ipateni i-silicon germanium kwizicelo eziphathekayo, kubandakanywa i-endoscopes, imaging kunye ne-fiber lasers.
