Izixhobo zokubeka i-optical waveguide ziyinxalenye ebalulekileyo yeenkqubo zonxibelelwano lwe-optical. Ezi zixhobo zisetyenziselwa ukubeka ngokuchanekileyo i-waveguide kwi-substrate ukuqinisekisa ukuba zinokuthumela imiqondiso ngokuchanekileyo nangokufanelekileyo. Enye yezona substrates zisetyenziswa kakhulu kwezi zixhobo yi-granite. Nangona kunjalo, nangona i-granite ineenzuzo ezininzi, kukwakho neziphene ezithile ezinokuchaphazela inkqubo yokuhlanganisa.
I-Granite lilitye lendalo eliqinileyo nelihlala ixesha elide, nto leyo eyenza ukuba ifaneleke ukusetyenziswa njengesiseko kwizixhobo zokubeka i-optical waveguide positioning. Izinzile kakhulu kubushushu kwaye iyamelana nemiphumo yokusingqongileyo, nto leyo eqinisekisa ukuba inokugcina imo kunye nesakhiwo sayo ngokuhamba kwexesha. I-Granite ikwanomlinganiselo ophantsi wokwanda kobushushu, nto leyo ethetha ukuba ayiguquguquki kakhulu xa ivezwa kutshintsho lobushushu. Olu phawu lubalulekile kuba luqinisekisa ukuba i-waveguide ayishukumi okanye ayitshintshi ngenxa yokwanda kobushushu.
Esinye seziphene ezibalulekileyo kwigranite kukurhabaxa komphezulu wayo. Igranite inomphezulu onemingxuma nongalinganiyo onokubangela iingxaki ngexesha lenkqubo yokuhlanganisa. Ekubeni ii-waveguides zifuna umphezulu ogudileyo nothe tyaba ukuqinisekisa ukuba zinokudlulisela imiqondiso ngokuchanekileyo, umphezulu orhabaxa wegranite unokukhokelela ekulahlekelweni kwesignali kunye nokuphazamiseka. Ngaphezu koko, umphezulu orhabaxa unokwenza kube nzima ukulungelelanisa nokubeka ii-waveguides ngokuchanekileyo.
Esinye isiphene segranite kukuba buthathaka kwayo. Igranite yinto eqinileyo neyomeleleyo, kodwa ikwabuthathaka. Ukuba buthathaka kwayo kuyenza ibe sengozini yokuqhekeka, ukuqhekeka, nokuqhekeka xa ijongene noxinzelelo kunye noxinzelelo. Ngexesha lenkqubo yokuhlanganisa, uxinzelelo kunye noxinzelelo olusetyenziswa kwi-granite substrate, njengakwinkqubo yokufakela, lunokubangela ukuqhekeka okanye iitships ezinokuchaphazela ukusebenza kwe-waveguides. Ukuba buthathaka kwe-granite substrate kuthetha ukuba ifuna ukuphathwa ngononophelo ukuze kuthintelwe ukonakala ngexesha lokuthuthwa nokufakwa.
I-granite ikwasengozini yokufuma kunye nokufuma, nto leyo enokubangela ukuba yande kwaye inciphe. Xa ichaphazeleka kukufuma, i-granite inokufunxa amanzi, nto leyo enokubangela ukuba idumbe kwaye idale uxinzelelo ngaphakathi kwezinto. Olu xinzelelo lunokubangela ukuqhekeka okukhulu okanye ukungasebenzi ngokupheleleyo kwe-substrate. Ukufuma kukwachaphazela nezincamathelisi ezisetyenziswa kwinkqubo yokuhlanganisa, nto leyo enokubangela ukuba iibhondi zibe buthathaka, nto leyo ekhokelela kwimiba efana nokulahleka kwesignali.
Ukuqukumbela, nangona igranite iyindawo ethandwayo yezixhobo zokubeka i-waveguide ye-optical, iseneziphene ezithile ezinokuchaphazela inkqubo yokuhlanganisa. Umphezulu orhabaxa wegranite unokukhokelela ekulahlekelweni kwesignali, ngelixa ukuqhekeka kwayo kuyenza ibe sesichengeni sokuqhekeka nokuqhekeka phantsi koxinzelelo. Okokugqibela, ukufuma kunye nokufuma kunokubangela umonakalo omkhulu kwi-substrate. Nangona kunjalo, ngokuphathwa ngononophelo kunye nokuqwalasela iinkcukacha, ezi ziphene zinokulawulwa ngokufanelekileyo ukuqinisekisa ukusebenza kakuhle kwesixhobo sokubeka i-waveguide.
