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 zozibini 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 ukuguqulwa okufunekayo kombane 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 enokurhweba.

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.

Ngoko ke, kuthathe iminyaka engaphezu kwe-10 ukusuka kwimizamo yokuqala ye-Badding yokudibanisa i-semiconductors ehlakaniphile kunye nemicu ye-optical elula kunye ne-fiber optical-electrical.

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