Imishini yokubeka i-Optical waveguide iyingxenye ebalulekile yezinhlelo zokuxhumana ezibonakalayo.Lawa madivayisi asetshenziselwa ukubeka ngokunembile ama-waveguides ku-substrate ukuze kuqinisekiswe ukuthi angakwazi ukudlulisa amasignali ngokunembile nangempumelelo.Enye yama-substrates asetshenziswa kakhulu kulawa madivaysi yigwadle.Kodwa-ke, nakuba i-granite inikeza izinzuzo eziningana, kukhona futhi ezinye iziphambeko ezingathinta inqubo yokuhlanganisa.
I-Granite iyitshe lemvelo eliqinile futhi elihlala isikhathi eside, elenza lilungele ukusetshenziswa njenge-substrate kumadivayisi okubeka i-waveguide optical.Inokuqina okuhle kakhulu kwe-thermal futhi imelana nemiphumela yemvelo, okuqinisekisa ukuthi ingakwazi ukugcina isimo sayo nesakhiwo ngokuhamba kwesikhathi.I-Granite nayo ine-coefficient ephansi yokunwetshwa kokushisa, okusho ukuthi ayigugi kakhulu lapho ibhekene nezinguquko zezinga lokushisa.Lesi sici sibalulekile ngoba siqinisekisa ukuthi amagagasi awanyakazi noma anyakaze ngenxa yokwanda kwezinga lokushisa.
Esinye seziphambeko eziphawulekayo ze-granite ubulukhuni bayo obungaphezulu.I-Granite ine-porous surface futhi engalingani engabangela izinkinga phakathi nenqubo yokuhlanganisa.Njengoba amagagasi e-waveguide edinga indawo ebushelelezi futhi eyisicaba ukuze aqinisekise ukuthi angadlulisela amasignali ngokunembile, indawo emagebhugebhu yegranite ingaholela ekulahlekeni kwesignali kanye nokuphazamiseka.Ngaphezu kwalokho, indawo emangelengele ingenza kube nzima ukuqondanisa nokubeka amagagasi ngokunembile.
Esinye isici se-granite ukuqina kwayo.I-Granite iyimpahla eqinile futhi eqinile, kodwa futhi i-brittle.I-brittleness yenza kube lula ukuqhekeka, ukuqhekeka, nokuphuka lapho ibhekene nengcindezi nengcindezi.Phakathi nenqubo yokuhlanganisa, ingcindezi nengcindezi ekhishwa ku-substrate yegwadle, efana nenqubo yokukhweza, ingabangela imifantu noma ama-chips angathinta ukusebenza kwamagagasi.I-brittleness ye-granite substrate iphinde isho ukuthi idinga ukuphathwa ngokucophelela ukugwema ukulimala ngesikhathi sokuthutha nokufakwa.
I-Granite nayo isengozini yomswakama kanye nomswakama, okungabangela ukuba yande futhi ifinyeze.Uma kuvezwa umswakama, i-granite ingakwazi ukumunca amanzi, okungabangela ukuthi ivuvuke futhi idale ukucindezeleka ngaphakathi kwezinto.Lokhu kucindezeleka kungaholela ekuqhekekeni okuphawulekayo noma ngisho nokwehluleka okuphelele kwe-substrate.Umswakama uphinde uthinte izinto zokunamathisela ezisetshenziswa enqubweni yokuhlanganisa, okungaholela kumabhondi abuthakathaka, okuholela ezindabeni ezinjengokulahlekelwa kwesignali.
Ukuphetha, ngenkathi i-granite iyi-substrate ethandwayo yamadivayisi okubeka i-waveguide optical, isenokukhubazeka okuthile okungathinta inqubo yokuhlanganisa.Indawo emagebhugebhu ye-granite ingaholela ekulahlekelweni kwesignali, kuyilapho ukuba brittleness kwayo kuyenza ibe sengozini yokuqhekeka nokuqhekeka ngaphansi kwengcindezi.Okokugcina, umswakama kanye nomswakama kungabangela umonakalo omkhulu ku-substrate.Kodwa-ke, ngokuphatha ngokucophelela nokunaka imininingwane, lezi ziphambeko zingaphathwa ngempumelelo ukuze kuqinisekiswe ukusebenza kahle kwedivayisi yokubeka i-waveguide.
