Kwa kulumikizana kwakukulu kolumikiza silicnor-roctuctronic iq radilator

Complect diicon -dy optoectronicIq moddulatorKulankhulana kwambiri
Kuchuluka kwa kuchuluka kwa kuchuluka kwa deta ya data ndi ma transceunts ogwiritsa ntchito bwino m'malo osungirako malo ayendetsa chitukuko cha magwiridwe antchito apamwambamakonzedwe owoneka bwino. Silicon yochokera ku Mactoectronic ukadaulo (SIPH) wakhala pulatifomu yabwino yopanga zigawo zingapo za prononic imodzi, zomwe zimapangitsa kuti zipsezi zikhale zopindulitsa. Nkhaniyi ilongosola za wonyamula zamakono zopatsira masilicon iq modwator yochokera ku Gisi Maams, yomwe imatha kugwira ntchito mobwerezabwereza mpaka 75 GAUD.
Kapangidwe kake ndi mawonekedwe
Wogwiritsa ntchito wa IQ ovomerezeka amatenga mawonekedwe atatu a mkono, monga tikuonera Chithunzi 1 (a). Opangidwa ndi ma Gsiyi atatu a Gsiwa ndipo atatu a thermo orsiters, kutengera mawonekedwe a symmetrical. Kuwala kolowera kumaphatikizidwa mu chip kudzera chowonjezera (GC) komanso ogawika m'njira zitatu kudzera mu 1 × 3 uncerode interfedometer (MMI). Pambuyo podutsa kudzera mwa kwengari ndi gawo la Phase, Kuwala kumabwezedwa ndi wina 1 × 3 MMI kenako ndikuphatikizidwa ndi fiber (SSMF).

Chithunzi 1: (a) Chithunzi cha Microscopic cha iq odumulator; . . (f) Kubera chonyamulira pa ndege yovuta. Monga taonera pa Chithunzi 1 (b), GSIA EAM ili ndi bandwidth ya electro-yokongoletsa. Chithunzi 1 (b) Kuyeza gawo la S21 ya gawo limodzi la Gsiwa Eam lomwe limagwiritsa ntchito gawo la 67 la Shz Optical Certiver (LCA). Ziwerengero 1 (c) ndi 1 (d) motero fanizo la zigawo za DC Formation ndi ma voltrage osiyanasiyana komanso kufalikira pamatumbo a 1555.
Monga taonera Chithunzi 1 (e), gawo lalikulu la kapangidwe kameneka ndikutha kupondereza onyamula matraical posintha gawo lophatikizidwa ndi mkono wa pakati. Kusiyana kwa magawo pakati pa mikono yapamwamba ndi yotsika ndi π / 2, komwe kumagwiritsidwa ntchito pokonzekera, pomwe gawo la magawo pakati pa mkono wapakati ndi -3 / 4. Kusintha kumeneku kumalola kusokonezedwa kwa onyamula, monga akuwonetsera mu ndege ya Chithunzi 1 (f).
Kuyeserera kwa Zoyeserera ndi Zotsatira
Kukhazikitsa kwamphamvu kwambiri kumawonetsedwa mu Chithunzi 2 (a). Infortor jeartor (Keyyight m8194a) imagwiritsidwa ntchito ngati gwero la siginecha, ndipo gawo la 60 la mahazi lomwe likufanana (ndi zophatikizika zophatikizika) zimagwiritsidwa ntchito ngati madalaivala oyendetsa. Magetsi am'madzi a Gsias Eam ndi -2.5 v, ndipo gawo lofanana la RF limagwiritsidwa ntchito kuchepetsa gawo lamagetsi pakati pa ine ndi njira.
Chithunzi 2: Gwiritsani ntchito laseri yakunja ya laseri (ECL) ndi mzere wa 100 KHz, Wheellethth ya 1555 nm, ndi mphamvu ya 12 dbm yonyamula madio. Pambuyo posinthira, chizindikiro chowoneka bwino chimakula pogwiritsa ntchitoErbium-dopded firmpurry.
Pakulandila, mawonedwe opepuka amawunika (OSA) amayang'anira zizindikiro za Spectrum ndi Zonyamula, monga zikuwonetsera pa Chithunzi 2 (b) kwa 70 GAUDS. Gwiritsani ntchito yolumikizira yolumikizirana yolumikizira kuti mulandire zikwangwani, zomwe zimakhala ndi sitedi ya 90 ndi anayi40 ghz makonda ojambula, and is connected to a 33 GHz, 80 GSa/s real-time oscilloscope (RTO) (Keysight DSOZ634A). Chiwiri cha ECL GAWO DZIKO LAPANSI la 100 KHz limagwiritsidwa ntchito ngati oscillator (lo). Chifukwa cha tranceter yomwe ikugwira ntchito yopanda tanthauzo, njira ziwiri zamagetsi zimagwiritsidwa ntchito potembenuka kwa analog-to-digito. Zambiri zimalembedwa pa RTT ndikukonzedwa pogwiritsa ntchito purosesa ya digito (DSP).
Monga taonera Chithunzi 2 (c), raddulator yoyesedwa idayesedwa pogwiritsa ntchito mtundu wa QPSk kuchokera 40 GMBUD ku 75 GAUD. Zotsatirazi zikuwonetsa kuti pansi pa 7% Chisankho Chovuta Patsogolo (HD-FIC) Mikhalidwe, mtengo ungafike 140 gb / s; Pansi pa nkhani 20% yosankhidwa yofewa yolakwika (SD-FIC), liwiro limatha kufikira 150 gb / s. Chithunzi chojambulidwa pa 70 Gbaud chikuwonetsedwa mu Chithunzi 2 (d). Zotsatira zake zimakhala zochepa ndi oscilloscope bandwidth ya 33 GHz, yomwe ikufanana ndi gulu la sigiriki wa pafupifupi 66 Gbaud.

Monga taonera Chithunzi 2 (b), mawonekedwe atatu a mkonowo amatha kupondereza onyamula zowoneka bwino ndi mtengo wolumala kupitilira 30 DB. Kapangidwe kameneka sikofunikira kuponderezedwa kwa chonyamulira ndipo amathanso kugwiritsidwa ntchito mu olandila omwe amafunikira matani onyamula kuti abwezeretse zizindikiro, monga Kramer Krongog (KK). Wonyamulayo amatha kusinthidwa kudzera mu gawo lapakati la mkono kuti akwaniritse chonyamulira chofuna kumbali ya kufinya (CSR).
Ubwino ndi Ntchito
Poyerekeza ndi matchal a ZehnderMzm modlators) Ndi a Optoelence-roluton-quelators, alucen iq moddulator ali ndi zabwino zambiri. Choyamba, imakhala yolumikizirana kukula kwake, oposa 10 ang'ono kuposa iQ modlators potengeraMach Zehnder(kupatula mapepala ogwirizanitsa), chifukwa chake kuchuluka kwa kuphatikiza ndikuchepetsa dera. Kachiwiri, mapangidwe a electode osankhidwa safuna kugwiritsa ntchito terminal oletsa, potero kuchepetsa ndalama ndi mphamvu pang'ono. Chachitatu, kupaka mtima komwe kumatha kukulitsa kuchepetsa mphamvu yofalitsa, kukonzanso mphamvu mphamvu.
Kuphatikiza apo, mabotolo am'madzi a Gsiwa Eam ndi okwera kwambiri (ma nanometer 30), ndikuchotsa kufunika kwa madera ambiri owongolera microwave modulators (MRM), potero kusintha kapangidwe kake.
IQ yothandiza iyi ndi yothandiza iQ yoyenerera kwambiri m'badwo wotsatira, kuwerengera kwa njira yaying'ono, ndi matembenuzidwe ang'onoang'ono ophatikizika m'malo osungirako zinthu, kumathandizira kuchuluka kwamphamvu komanso kulumikizana kwamphamvu kwambiri.
Wonyamula silicon IQ aductor yowonetsera bwino kwambiri, yokhala ndi deta yotumiza deta mpaka 150 gb / s pansi pa 20% sd mikhalidwe ya fec. Kapangidwe kake ka 3 kochokera ku Gisi Eam kuli ndi zabwino zokhudzana ndi mawonekedwe am'madzi, mphamvu zamagetsi, ndi kupanga kuphweka. Khalayi ili ndi kuthekera koletsa kapena kusintha chonyamulira cham'maso ndipo chitha kuphatikizidwa ndi zojambula zolumikizirana ndi Kramer Krongog (KK) Kuzindikira kwa matembenuzidwe osiyanasiyana. Kuchita zinthu zomwe zikuwonetsedwa kumayendetsa kukwaniritsidwa kwa matembenuzidwe ophatikizidwa kwambiri ndi ogwiritsa ntchito makina omwe akuyenera kulumikizana ndi kuchuluka kwa chidziwitso cha data kwambiri mu malo opangira ma data ndi minda ina.
