Uruhare rwa firime yoroheje ya lithium niobate muri moderi ya electro-optique

Uruhare rwa firime yoroheje ya lithium niobate muriamashanyarazi ya optique
Kuva uruganda rwatangira kugeza ubu, ubushobozi bwitumanaho rya fibre imwe bwiyongereyeho miriyoni miriyoni, kandi umubare muto wubushakashatsi bugezweho bwarenze miriyoni mirongo. Lithium niobate yagize uruhare runini hagati yinganda zacu. Muminsi yambere ya optique ya fibre itumanaho, modulisiyo yikimenyetso cya optique yahujwe neza kurilaser. Ubu buryo bwo guhinduranya buremewe murwego rwo hasi cyangwa intera ngufi ya porogaramu. Kubyihuta byihuse kandi birebire birebire, hazaba umurongo mugari udahagije kandi umuyoboro woherejwe uhenze cyane kugirango uhuze intera ndende.
Hagati ya fibre optique itumanaho, ibimenyetso byerekana byihuse kandi byihuse kugirango hongerwe ubushobozi bwitumanaho, kandi uburyo bwo guhitamo ibimenyetso bya optique butangira gutandukana, kandi uburyo butandukanye bwo guhinduranya bukoreshwa muguhuza intera ndende no guhuza intera ndende. . Guhindura ibiciro bidahenze bikoreshwa muguhuza intera ndende, kandi "moderi ya electro-optique" itandukanye ikoreshwa mumurongo muremure wa trunk, itandukanijwe na laser.
Moderi ya electro-optique ikoresha imiterere ya interineti ya Machzender kugirango ihindure ibimenyetso, urumuri ni umuyagankuba wa electromagnetique, umuyagankuba wa electromagnetic wumuvuduko ukenera gukenera kugenzura neza, icyiciro na polarisiyasi. Dukunze kuvuga ijambo, ryitwa interrence fringes, urumuri numwijima wijimye, umucyo ni agace kongerera ingufu za electromagnetique, umwijima nigice cya interineti ikora interineti itera imbaraga gucika intege. Kwivanga kwa Mahzender ni ubwoko bwa interterometero ifite imiterere yihariye, niyo ngaruka yo kugenzura igenzurwa no kugenzura icyiciro cy'igiti kimwe nyuma yo kugabana ibiti. Muyandi magambo, ibisubizo bivanze birashobora kugenzurwa no kugenzura icyiciro.
Lithium niobate ibi bikoresho bikoreshwa mugutumanaho kwa fibre optique, ni ukuvuga, irashobora gukoresha urwego rwa voltage (ikimenyetso cyamashanyarazi) kugirango igenzure icyiciro cyumucyo, kugirango igere kumihindagurikire yikimenyetso cyumucyo, aribwo isano iri hagati ya electro-optique modulator na lithium niobate. Modulator yacu yitwa electro-optique modulator, ikeneye gusuzuma uburinganire bwikimenyetso cyamashanyarazi hamwe nubwiza bwikimenyetso cya optique. Ububasha bw'amashanyarazi ya indium fosifide na fotonike ya silicon nibyiza kuruta ibya lithium niobate, kandi ubushobozi bwa signal optique buracogora gato ariko burashobora no gukoreshwa, butanga uburyo bushya bwo gukoresha amahirwe yisoko.
Usibye ibikoresho byiza byamashanyarazi, indium fosifide na silicon Photonics bifite ibyiza bya miniaturisation no kwishyira hamwe lithium niobate idafite. Indium fosifike ni ntoya kuruta lithium niobate kandi ifite impamyabumenyi ihanitse yo kwishyira hamwe, kandi fotone ya silicon ni ntoya kuruta indium fosifide kandi ifite impamyabumenyi ihanitse. Umutwe wa lithium niobate nka amodulatorni inshuro ebyiri nka indium fosifide, kandi irashobora kuba modulator gusa kandi ntishobora guhuza indi mirimo.
Kugeza ubu, moderi ya electro-optique yinjiye mugihe cya miliyari 100 yikigereranyo cyibimenyetso, (128G ni miliyari 128), kandi lithium niobate yongeye kurugamba rwo kwitabira amarushanwa, kandi yizera ko azayobora iki gihe cya vuba. ejo hazaza, gufata iyambere mukwinjiza isoko ryibiciro bya miliyari 250. Kugirango lithium niobate yigarurire iri soko, birakenewe gusesengura icyo indium fosifide na fotone ya silicon ifite, ariko lithium niobate ntabwo. Nubushobozi bwamashanyarazi, kwishyira hamwe, miniaturizasi.
Guhindura lithium niobate iri mu mpande eshatu, Inguni ya mbere nuburyo bwo kuzamura ubushobozi bwamashanyarazi, Inguni ya kabiri nuburyo bwo kunoza kwishyira hamwe, naho Inguni ya gatatu nuburyo bwo kugabanya miniaturize. Igisubizo kuri izi mpande eshatu za tekiniki gisaba igikorwa kimwe gusa, ni ukuvuga, kunanura firime ya lithium niobate, fata urwego ruto cyane rwibikoresho bya lithium niobate nka optique yumurongo wa optique, urashobora kongera gukora electrode, kuzamura ubushobozi bwamashanyarazi, kunoza umurongo mugari no guhindura imikorere yikimenyetso cyamashanyarazi. Kongera ubushobozi bw'amashanyarazi. Iyi firime irashobora kandi kwomekwa kuri silicon wafer, kugirango igere kubufatanye, lithium niobate nka modulator, ahasigaye kwishyira hamwe kwa silicon, ubushobozi bwa miniaturisiyonike ya silicon biragaragara kuri bose, firime ya lithium niobate hamwe na silicon yumucyo bivanze, kunoza kwishyira hamwe , mubisanzwe byagezweho miniaturizasiya.
Mu minsi ya vuba, moderi ya electro-optique igiye kwinjira mugihe cyikigereranyo cya miliyari 200 yikigereranyo, ibibi bya optique ya indium fosifide na fotone ya silicon bigenda bigaragara cyane, kandi ibyiza bya optique ya lithium niobate biragenda birushaho kwiyongera icyamamare, na lithium niobate yoroheje ya firime itezimbere ibibi byibi bikoresho nka modulator, kandi inganda zibanda kuri iyi "thin film lithium niobate", ni ukuvuga firime yorohejelithium niobate modulator. Uru nirwo ruhare rwa firime yoroheje lithium niobate mubijyanye na moderi ya electro-optique.
