Optical waveguide positioning devices yog ib feem tseem ceeb ntawm kev sib txuas lus kho qhov muag.Cov cuab yeej siv no yog siv los ua kom raug qhov chaw waveguides ntawm lub substrate kom ntseeg tau tias lawv tuaj yeem xa cov teeb liab kom raug thiab ua tau zoo.Ib qho ntawm feem ntau siv substrates rau cov khoom siv no yog granite.Txawm li cas los xij, thaum granite muaj ntau qhov zoo, kuj tseem muaj qee qhov tsis xws luag uas tuaj yeem cuam tshuam cov txheej txheem sib dhos.
Granite yog lub pob zeb ntuj uas yog ib qho nyuaj thiab ruaj khov, uas ua rau nws zoo tagnrho rau siv los ua substrate hauv optical waveguide positioning devices.Nws muaj kev ruaj ntseg zoo heev thiab tiv taus ib puag ncig, uas ua kom nws muaj peev xwm tswj tau nws cov duab thiab cov qauv hauv lub sijhawm.Granite kuj muaj cov coefficient tsawg ntawm thermal expansion, uas txhais tau hais tias nws tsis deform loj thaum raug kub hloov.Cov yam ntxwv no yog qhov tseem ceeb vim nws ua kom cov waveguide tsis txav los yog hloov vim thermal expansion.
Ib qho ntawm cov teeb meem tseem ceeb ntawm granite yog nws qhov roughness.Granite muaj qhov ntxeem tau thiab tsis sib xws uas tuaj yeem ua rau muaj teeb meem thaum lub sijhawm sib dhos.Txij li cov waveguides xav tau qhov chaw du thiab tiaj tus kom ntseeg tau tias lawv tuaj yeem xa cov teeb liab kom raug, qhov ntxhib ntawm granite tuaj yeem ua rau lub teeb liab poob thiab cuam tshuam.Ntxiv mus, qhov ntxhib saum npoo tuaj yeem ua rau nws nyuaj rau kev sib dhos thiab tso cov waveguides kom raug.
Lwm qhov tsis xws ntawm granite yog nws brittleness.Granite yog cov khoom siv tawv thiab muaj zog, tab sis nws kuj yog nkig.Lub brittleness ua rau nws yooj yim rau tawg, chipping, thiab tawg thaum raug kev nyuaj siab thiab siab.Thaum lub sij hawm sib dhos txheej txheem, lub siab thiab kev ntxhov siab exerted ntawm granite substrate, xws li los ntawm cov txheej txheem mounting, tuaj yeem ua rau cov kab nrib pleb lossis chips uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov waveguide.Lub brittleness ntawm granite substrate kuj txhais tau hais tias nws yuav tsum tau ceev faj tuav kom tsis txhob muaj kev puas tsuaj thaum lub sij hawm thauj mus los thiab installation.
Granite kuj yog qhov yooj yim rau cov dej noo thiab av noo, uas tuaj yeem ua rau nws nthuav thiab cog lus.Thaum raug cov dej noo, granite tuaj yeem nqus dej, uas tuaj yeem ua rau nws o thiab tsim kev ntxhov siab hauv cov khoom.Qhov kev ntxhov siab no tuaj yeem ua rau muaj kev tawg loj lossis txawm tias qhov ua tsis tiav ntawm substrate.Cov dej noo kuj tseem cuam tshuam rau cov nplaum uas siv rau hauv cov txheej txheem sib dhos, uas tuaj yeem ua rau cov ntawv cog lus tsis muaj zog, ua rau muaj teeb meem xws li teeb liab poob.
Txhawm rau xaus, thaum granite yog qhov nrov substrate rau kho qhov muag waveguide positioning li, nws tseem muaj qee qhov tsis xws luag uas tuaj yeem cuam tshuam cov txheej txheem sib dhos.Granite qhov ntxhib saum npoo tuaj yeem ua rau lub teeb liab poob, thaum nws brittleness ua rau nws yooj yim rau tawg thiab chipping nyob rau hauv siab.Thaum kawg, noo noo thiab av noo tuaj yeem ua rau muaj kev puas tsuaj loj rau lub substrate.Txawm li cas los xij, nrog kev ua tib zoo tuav thiab ua tib zoo saib xyuas kom meej, cov kev tsis zoo no tuaj yeem tswj tau zoo kom ntseeg tau tias qhov kev ua tau zoo ntawm lub waveguide positioning device.
