LightCounting (LC) tau tshaj tawm 9th tsab ntawm nws cov Silicon Photonics kev lag luam daim ntawv tshaj tawm, muab kev lag luam tshiab kev kwv yees rau linear-driven pluggable thiab co-packaged optical devices.
Ntau tus kws tshaj lij hauv kev lag luam kwv yees tias Silicon Photonics (SiP) yuav hloov kho cov khoom siv kho qhov muag thiab kev lag luam module los ntawm kev ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig ntau ntawm kev sib txuas kho qhov muag. Kev twv seb thaum twg qhov kev hloov pauv no yuav tshwm sim tau nyuaj: ib ntus, zoo li tsis muaj dab tsi tshwm sim txog tam sim ntawd, qhov kev hloov pauv tau pom meej. Tej zaum tsis pom los ntawm ntau tus, Silicon Photonics twb yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv kev lag luam thoob ntiaj teb optical transceiver, raws li qhia hauv daim duab hauv qab no.
LC tau kwv yees tias kev lag luam sib koom ntawm Silicon Photonics modulator transceivers yuav nce los ntawm 24 feem pua hauv 2022 mus rau 44 feem pua hauv 2028. Qhov tseem ceeb tshaj yog tias cov modulators raws li lwm cov ntaub ntawv nyias nyias tuaj yeem tsim los ntawm silicon chips thiab sib xyaw nrog ntau yam khoom siv kho qhov muag. thiab hluav taws xob ICs siv Silicon Photonics ua lub platform. Cov ntaub ntawv tam sim no suav nrog nyias-zaj duab xis lithium niobate (TFLN), barium titanate (BTO), thiab electro-optic polymers, uas LC ua ke rau hauv qeb "TFLN thiab Lwm tus" hauv daim duab.
Lwm qhov kev hloov pauv zoo siab hauv kev lag luam yog kev txais yuav ntawm linear-driven pluggable optics (LPO) transceivers thiab co-packaged optical devices (CPO). Ob qho kev daws teeb meem txo qis kev siv hluav taws xob piv rau cov qauv retimed transceivers nrog built-in PAM4 DSP chips. Tshem tawm qhov xav tau rau DSP txuag lub zog tab sis yuav tsum muaj SerDes nyuaj rau kev tsav tsheb ncaj qha.
Broadcom's 100G SerDes tau tsim nrog CPO hauv siab tab sis zoo li txhawb LPO ib yam nkaus. Qhov kev ua tau zoo thaum ntxov ntawm 800G LPO modules uas tau tsav los ntawm 100G SerDes tau zoo heev. Txawm li cas los xij, LPO tsis zoo li ua haujlwm nrog 200G SerDes, ua rau CPO tsuas yog xaiv rau 1.6T chaw nres nkoj.
Puas yuav tag nrho LPO thiab CPO kev daws teeb meem raws li Silicon Photonics? Nws tsis zoo li, tab sis Silicon Photonics yog tus thawj coj tam sim no thiab lub platform zoo tshaj plaws rau kev sib xyaw cov ntaub ntawv tshiab. Silicon Photonics modulators tam sim no yog qhov kev xaiv zoo tshaj plaws rau cov qauv tsim tawm txij li GaAs ncaj qha hloov kho lasers (DML) thiab InP electro-absorption modulated lasers (EML) yog cov khoom siv "nonlinear" ntau dua. Tsis yog txhua qhov kev daws teeb meem yuav siv Silicon Photonics modulators, tab sis nws yog qhov tseeb tias tag nrho LPO / CPO li, tshwj tsis yog VCSELs, yuav ua raws li Silicon Photonics platform. Tag nrho cov ntaub ntawv tshiab (TFLN, BTO, thiab polymers) yuav koom ua ke nrog lwm cov khoom siv kho qhov muag thiab cov khoom siv hluav taws xob siv Silicon Photonics platform.
Tshaj li tsib xyoos tom ntej no los yog ntev dua, cov khoom lag luam retimed pluggable yuav txuas ntxiv ua lag luam. Txawm li cas los xij, LPO / CPO cov chaw nres nkoj yuav suav txog ntau dua 30 feem pua ntawm tag nrho 800G thiab 1.6T cov chaw nres nkoj xa tawm los ntawm 2026 txog 2028. Raws li ib txwm muaj, tsis muaj dab tsi yuav tshwm sim rau ib pliag kom txog thaum tam sim ntawd, qhov kev hloov pauv no tshwm sim ua ntej peb txhua tus.
