Uruhare rwa filime nto ya lithium niobate muri modulator ya electro-optic

Uruhare rwa firime nto ya lithium niobate murimodulator y'amashanyarazi n'amatara
Kuva mu ntangiriro z'inganda kugeza ubu, ubushobozi bwo gutumanaho hakoreshejwe fibre imwe bwiyongereyeho incuro miliyoni, kandi ubushakashatsi bugezweho bwarenze inshuro miliyoni mirongo. Lithium niobate yagize uruhare runini hagati mu nganda zacu. Mu minsi ya mbere y'itumanaho rya fibre optique, uburyo ikimenyetso cy'urumuri cyahindukaga bwahuzwaga neza ku buryo butaziguye.laserUbu buryo bwo guhinduranya amakuru bwemewe mu buryo bworoshye cyangwa mu buryo bw'intera ngufi. Ku buryo bwo guhinduranya amakuru bwihuse cyane no mu buryo bw'intera ndende, nta bandwidth ihagije izaba ihari kandi umuyoboro wo kohereza amakuru urahenze cyane ku buryo udashobora kugera ku buryo bwo guhinduranya amakuru bw'intera ndende.
Hagati mu itumanaho rya fibre optique, uburyo bwo guhindura ibimenyetso bwihuta kandi bwihuse kugira ngo buhuze n’ubwiyongere bw’ubushobozi bw’itumanaho, kandi uburyo bwo guhindura ibimenyetso optique butangira gutandukana, kandi uburyo butandukanye bwo guhindura amakuru bukoreshwa mu miyoboro migufi n’imiyoboro miremire. Uburyo bwo guhindura amakuru buhendutse bukoreshwa mu miyoboro migufi, kandi "electro-optique modulator" itandukanye ikoreshwa mu miyoboro miremire, itandukanyijwe na laser.
Modulator ya Electro-optic ikoresha imiterere ya Machzender interference kugira ngo ihindure ikimenyetso, urumuri ni umuraba wa electromagnetic, interference ihamye ya electromagnetic wave ikenera frequency ihamye yo kugenzura, phase na polarization. Dukunze kuvuga ijambo, ryitwa interference fringes, urumuri n'umurambararo wijimye, bright ni agace aho interference ya electromagnetic irushaho kwiyongera, umwijima ni agace aho interference ya electromagnetic itera ingufu gucika intege. Interference ya Mahzender ni ubwoko bwa interferometer ifite imiterere yihariye, ikaba ari ingaruka zo kubangamira zigenzurwa no kugenzura phase y'umuraba umwe nyuma yo gucamo umuraba. Mu yandi magambo, ibisubizo byo kubangamira bishobora kugenzurwa no kugenzura phase yo kubangamira.
Lithium niobate iyi mashini ikoreshwa mu itumanaho rya fibre optique, ni ukuvuga ko ishobora gukoresha urwego rwa voltage (signal electrical) kugira ngo igenzure intera y'urumuri, kugira ngo igere ku ihinduka ry'ikimenyetso cy'urumuri, ari na yo sano iri hagati ya modulator ya electro-optical na lithium niobate. Modulator yacu yitwa modulator ya electro-optic, igomba gusuzuma ubusugire bw'ikimenyetso cy'amashanyarazi ndetse n'ubwiza bw'ikimenyetso cy'urumuri. Ubushobozi bw'ikimenyetso cy'amashanyarazi cya indium phosfide na silicon photonics ni bwiza kurusha ubwa lithium niobate, kandi ubushobozi bw'ikimenyetso cy'urumuri ni buke gato ariko bushobora no gukoreshwa, ibyo bikaba bitanga uburyo bushya bwo gukoresha amahirwe yo ku isoko.
Uretse imiterere myiza y'amashanyarazi, indium phosfide na silicon photonics bifite ibyiza byo gukora miniaturization no guhuza ibintu bitandukanye na lithium niobate. Indium phosfide ni ntoya ugereranije na lithium niobate kandi ifite urugero rwo hejuru rwo guhuza ibintu, naho silicon photons ni nto ugereranije na indium phosfide kandi ifite urugero rwo hejuru rwo guhuza ibintu. Umutwe wa lithium niobate nk'umuntumodulatorIfite uburebure bukubye kabiri ubwinshi bwa phosfide ya indium, kandi ishobora kuba modulator gusa kandi ntishobora guhuza izindi nshingano.
Kuri ubu, modulator y’amashanyarazi yinjiye mu gihe cy’igipimo cya miliyari 100 z’ibimenyetso, (128G ni miliyari 128), kandi lithium niobate yongeye gutera intambwe yo kwitabira iri rushanwa, kandi yizeye kuyobora iki gihe mu gihe cya vuba, ifata iya mbere mu kwinjira ku isoko ry’igipimo cya miliyari 250 z’ibimenyetso. Kugira ngo lithium niobate yongere kwigarurira iri soko, ni ngombwa gusesengura icyo indium phosfide na silicon fotoni bifite, ariko lithium niobate ntabwo ifite. Ubwo ni ubushobozi bw’amashanyarazi, guhuza cyane, miniaturization.
Impinduka ya lithium niobate iri mu mfuruka eshatu, inguni ya mbere ni uburyo bwo kunoza ubushobozi bw'amashanyarazi, inguni ya kabiri ni uburyo bwo kunoza ihuza, naho inguni ya gatatu ni uburyo bwo kugabanya. Igisubizo kuri izi nguni eshatu za tekiniki gisaba igikorwa kimwe gusa, ni ukuvuga, gukata ibikoresho bya lithium niobate, gukuramo urwego rworoshye cyane rw'ibikoresho bya lithium niobate nk'umurongo w'amashanyarazi, ushobora kuvugurura electrode, kunoza ubushobozi bw'amashanyarazi, kunoza imikorere y'umurambararo n'imikorere y'ikimenyetso cy'amashanyarazi. Kongera ubushobozi bw'amashanyarazi. Iyi filime ishobora kandi gushyirwa kuri silicon wafer, kugira ngo igere ku guhuza guvanze, lithium niobate nk'umuyobora, ibindi byose bijyanye no guhuza silicon photon, ubushobozi bwa silicon photon miniaturization buragaragarira bose, filime ya lithium niobate n'urumuri rwa silicon light mixed integration, kunoza ihuza, miniaturization yagezweho karemano.
Mu gihe cya vuba aha, modulator y'amashanyarazi igiye kwinjira mu gihe cy'ikigereranyo cya miliyari 200, ikibazo cy'urumuri rwa indium phosfide na silicon fotoni kirimo kugaragara cyane, kandi inyungu y'urumuri rwa lithium niobate iri kugenda igaragara cyane, kandi filime nto ya lithium niobate yongera ingaruka mbi z'iki gikoresho nk'umukoresha, kandi inganda zibanda kuri iyi "filime nto ya lithium niobate", ni ukuvuga filime ntoya.modulator ya lithiamu niobateUru ni uruhare rwa lithium niobate mu bijyanye na modulators za electro-optical.
