Zolakwika za msonkhano wa granite wa chipangizo chowongolera mafunde cha Optical waveguide

Zipangizo zoyikira mafunde a kuwala ndi gawo lofunikira kwambiri pa njira zolumikizirana ndi kuwala. Zipangizozi zimagwiritsidwa ntchito poyika mafunde molondola pa substrate kuti zitsimikizire kuti zimatha kutumiza zizindikiro molondola komanso moyenera. Chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri pazida izi ndi granite. Komabe, ngakhale granite ili ndi zabwino zingapo, palinso zolakwika zina zomwe zingakhudze njira yopangira.

Granite ndi mwala wachilengedwe womwe ndi wolimba komanso wolimba, zomwe zimapangitsa kuti ukhale woyenera kugwiritsidwa ntchito ngati substrate mu zida zowunikira mafunde. Uli ndi kukhazikika kwabwino kwa kutentha ndipo umalimbana ndi zotsatira zachilengedwe, zomwe zimatsimikizira kuti ukhoza kusunga mawonekedwe ake ndi kapangidwe kake pakapita nthawi. Granite ilinso ndi coefficient yochepa ya kukula kwa kutentha, zomwe zikutanthauza kuti siwonongeka kwambiri ikakumana ndi kusintha kwa kutentha. Khalidweli ndi lofunikira chifukwa limatsimikizira kuti mafunde sasuntha kapena kusuntha chifukwa cha kukula kwa kutentha.

Chimodzi mwa zolakwika zazikulu za granite ndi kuuma kwake pamwamba. Granite ili ndi malo obowoka komanso osafanana omwe angayambitse mavuto panthawi yopangira. Popeza ma waveguide amafunika malo osalala komanso athyathyathya kuti atsimikizire kuti amatha kutumiza zizindikiro molondola, malo obowoka a granite angayambitse kutayika kwa zizindikiro ndi kusokoneza. Kuphatikiza apo, malo obowoka angapangitse kuti zikhale zovuta kulinganiza ndikuyika ma waveguide molondola.

Vuto lina la granite ndi kufooka kwake. Granite ndi chinthu cholimba komanso cholimba, komanso ndi chofooka. Kufooka kwake kumapangitsa kuti ikhale yosweka, yosweka, komanso yosweka ikakumana ndi kupsinjika ndi kupsinjika. Panthawi yomanga, kupsinjika ndi kupsinjika komwe kumachitika pa granite substrate, monga kuchokera pakuyiyika, kungayambitse ming'alu kapena zidutswa zomwe zingakhudze magwiridwe antchito a mafunde. Kufooka kwa granite substrate kumatanthauzanso kuti imafunika kusamalidwa mosamala kuti isawonongeke panthawi yonyamula ndi kuyiyika.

Granite imakhudzidwanso ndi chinyezi komanso chinyezi, zomwe zingayambitse kuti ikule ndikuchepa. Ikakumana ndi chinyezi, granite imatha kuyamwa madzi, zomwe zingayambitse kuti itukuke ndikupanga kupsinjika mkati mwa chinthucho. Kupsinjika kumeneku kungayambitse ming'alu yayikulu kapena kulephera kwathunthu kwa substrate. Chinyezi chimakhudzanso zomatira zomwe zimagwiritsidwa ntchito pomanga, zomwe zingayambitse zomangira zofooka, zomwe zingayambitse mavuto monga kutayika kwa chizindikiro.

Pomaliza, ngakhale granite ndi chinthu chodziwika bwino chomwe chimagwiritsidwa ntchito popanga zida zowongolera mafunde, komabe chili ndi zolakwika zina zomwe zingakhudze njira yopangira. Malo owuma a granite amatha kupangitsa kuti chizindikirocho chitayike, pomwe kufooka kwake kumapangitsa kuti chikhale chosavuta kusweka ndi kusweka chifukwa cha kupanikizika. Pomaliza, chinyezi ndi chinyezi zimatha kuwononga kwambiri gawo lapansi. Komabe, posamalira mosamala komanso mosamala tsatanetsatane, zolakwika izi zitha kusamalidwa bwino kuti zitsimikizire kuti chipangizo chowongolera mafunde chikugwira ntchito bwino.
