Amaphutha omhlangano we-granite womkhiqizo wedivayisi yokubeka i-Optical waveguide

Amadivayisi okubeka amagagasi okukhanya ayingxenye ebalulekile yezinhlelo zokuxhumana ze-optical. Lawa madivayisi asetshenziselwa ukubeka amagagasi okukhanya ngokunembile ku-substrate ukuqinisekisa ukuthi angadlulisela amasignali ngokunembile nangokusebenza kahle. Enye ye-substrate esetshenziswa kakhulu kulawa madivayisi yi-granite. Kodwa-ke, yize i-granite inikeza izinzuzo eziningana, kukhona futhi amaphutha angathinta inqubo yokuhlanganisa.

I-Granite iyitshe lemvelo eliqinile futhi elihlala isikhathi eside, okwenza libe yindawo ekahle yokusetshenziswa njengesisekelo kumadivayisi okubeka amagagasi okukhanya. Inokuzinza okuhle kakhulu kokushisa futhi imelana nemiphumela yemvelo, okuqinisekisa ukuthi ingagcina isimo sayo nesakhiwo sayo ngokuhamba kwesikhathi. I-Granite iphinde ibe ne-coefficient ephansi yokwanda kokushisa, okusho ukuthi ayiguquki kakhulu lapho ivezwa izinguquko zokushisa. Lesi sici sibalulekile ngoba siqinisekisa ukuthi amagagasi okushisa awashukumi noma ashintshe ngenxa yokwanda kokushisa.

Esinye seziphambeko ezibalulekile ze-granite ukuba lukhuni kobuso bayo. I-granite inobuso obunezimbobo nobungalingani obungabangela izinkinga ngesikhathi senqubo yokuhlanganisa. Njengoba ama-waveguide adinga ubuso obubushelelezi nobuyisicaba ukuqinisekisa ukuthi angadlulisela izimpawu ngokunembile, ubuso obuqinile be-granite bungaholela ekulahlekelweni kwesignali kanye nokuphazamiseka. Ngaphezu kwalokho, ubuso obuqinile bungenza kube nzima ukuqondisa nokubeka ama-waveguide ngokunembile.

Esinye isici se-granite ukuphuka kwayo. I-granite iyinto eqinile futhi eqinile, kodwa futhi iyaphuka. Ukuphuka kwayo kwenza ibe sengozini yokuqhekeka, ukuqhekeka, nokuphuka lapho ivezwa ekucindezelekeni nasekucindezelweni. Ngesikhathi senqubo yokuhlanganisa, ingcindezi nokucindezeleka okwenziwa ku-granite substrate, njengasenqubweni yokufaka, kungabangela imifantu noma ama-chips angathinta ukusebenza kwama-waveguides. Ukuphuka kwe-granite substrate kusho nokuthi idinga ukuphathwa ngokucophelela ukuze kugwenywe umonakalo ngesikhathi sokuthuthwa nokufakwa.

I-granite nayo isengozini yomswakama kanye nomswakama, okungabangela ukuthi ikhule futhi inciphe. Uma ivezwa umswakama, i-granite ingamunca amanzi, okungabangela ukuthi ivuvuke futhi idale ukucindezeleka ngaphakathi kwezinto. Lokhu kucindezeleka kungaholela ekuqhekekeni okukhulu noma ngisho nasekuhlulekeni okuphelele kwe-substrate. Umswakama uphinde uthinte izinamathiselo ezisetshenziswa enqubweni yokuhlanganisa, okungabangela izibopho ezibuthakathaka, okuholela ezinkingeni ezifana nokulahlekelwa isignali.

Ukuphetha, yize i-granite iyindawo ethandwayo yamadivayisi okubeka i-waveguide, isenezinye izinkinga ezingathinta inqubo yokuhlanganisa. Ubuso obuqinile be-granite bungaholela ekulahlekelweni kwesignali, kuyilapho ukuphuka kwayo kuyenza ibe sengozini yokuqhekeka nokuqhekeka ngaphansi kwengcindezi. Okokugcina, umswakama kanye nomswakama kungabangela umonakalo omkhulu ku-substrate. Kodwa-ke, ngokuphathwa ngokucophelela nokunaka imininingwane, lezi ziphazamiso zingaphathwa ngempumelelo ukuqinisekisa ukusebenza kahle kwedivayisi yokubeka i-waveguide.
