Izixhobo zokubeka i-Optical waveguide ziyinxalenye ebalulekileyo yeenkqubo zonxibelelwano lwamehlo.Ezi zixhobo zisetyenziselwa ukubeka ngokuchanekileyo i-waveguides kwi-substrate ukuqinisekisa ukuba ziyakwazi ukuhambisa izibonakaliso ngokuchanekileyo nangokufanelekileyo.Enye yezona zixhobo zisetyenziswa ngokuqhelekileyo kwezi zixhobo yigranite.Nangona kunjalo, ngelixa i-granite ibonelela ngeenzuzo ezininzi, kukwakho nezinye iziphene ezinokuchaphazela inkqubo yendibano.
I-Granite lilitye lendalo elinzima kwaye lihlala ixesha elide, elenza ukuba lilungele ukusetyenziswa njenge-substrate kwizixhobo zokubeka i-waveguide optical.Inozinzo oluhle kakhulu lwe-thermal kwaye luchasene nemiphumo yokusingqongileyo, eqinisekisa ukuba inokugcina imilo kunye nesakhiwo sayo ngexesha.I-Granite nayo ine-coefficient ephantsi yokwandiswa kwe-thermal, oku kuthetha ukuba ayiguquki kakhulu xa ibonakaliswe kutshintsho lobushushu.Olu phawu lubalulekile kuba luqinisekisa ukuba ii-waveguides azishukumi okanye aziguquki ngenxa yokwanda kwe-thermal.
Esinye seziphene ezibalulekileyo zegranite buburhabaxa bomphezulu.I-Granite ine-porous surface kwaye ingalinganiyo enokubangela iingxaki ngexesha lenkqubo yokuhlanganisa.Ekubeni i-waveguides ifuna indawo egudileyo kunye nethe tyaba ukuqinisekisa ukuba inokuhambisa imiqondiso ngokuchanekileyo, indawo erhabaxa yegranite inokukhokelela ekulahlekeni komqondiso kunye nokuphazamiseka.Ngaphezu koko, umphezulu orhabaxa unokwenza kube nzima ukulungelelanisa kunye nokubeka amaza ngokuchanekileyo.
Esinye isiphene segranite kukuqhwala kwayo.I-Granite yimathiriyeli eqinile kwaye eyomeleleyo, kodwa iphinde ibe brittle.I-brittleness yenza kube lula ukuqhekeka, ukuqhekeka, kunye nokuqhekeka xa kuvezwe kuxinzelelo kunye noxinzelelo.Ngethuba lenkqubo yokuhlanganisana, uxinzelelo kunye noxinzelelo olwenziwa kwi-granite substrate, efana nenkqubo yokunyuka, inokubangela ukuqhekeka okanye ii-chips ezinokuchaphazela ukusebenza kwee-waveguides.I-brittleness ye-granite substrate ikwathetha ukuba ifuna ukuphathwa ngokucophelela ukuphepha umonakalo ngexesha lokuthutha kunye nokufakwa.
I-Granite nayo isengozini yokufuma kunye nokufuma, okunokubangela ukuba yande kwaye ifinyeze.Xa ibonakaliswe kumswakama, i-granite inokufunxa amanzi, enokubangela ukuba idumbe kwaye idale uxinzelelo ngaphakathi kwezinto.Olu xinzelelo lunokukhokelela ekuqhekekeni okukhulu okanye ukungaphumeleli ngokupheleleyo kwe-substrate.Ubumanzi bubuye buchaphazele ama-adhesives asetyenziswe kwinkqubo yokuhlanganisana, enokubangela ukuba kubekho iibhondi ezibuthathaka, ezikhokelela kwimiba efana nokulahleka komqondiso.
Ukuqukumbela, ngelixa i-granite iyindawo esezantsi edumileyo yezixhobo zokubeka i-waveguide optical, isenazo iziphene ezinokuchaphazela inkqubo yokuhlanganisa.Umphezulu orhabaxa weGranite unokukhokelela ekulahlekeni komqondiso, ngelixa ukuqina kwayo kuyenza ibe sesichengeni sokuqhekeka kunye nokuqhekeka phantsi koxinzelelo.Ekugqibeleni, ukufuma kunye nokufuma kunokubangela umonakalo omkhulu kwi-substrate.Nangona kunjalo, ngokuphathwa ngononophelo kunye nengqalelo kwiinkcukacha, ezi ziphene zinokulawulwa ngokufanelekileyo ukuze kuqinisekiswe ukusebenza kakuhle kwesixhobo sokumisa i-waveguide.
