I-Compact Silicon-esekwe kwi-OptoelectronicI-IQ ModulatorUnxibelelwano oluphezulu lwesantya esiphezulu
Imfuno eyandayo yokuphelisa idatha ephezulu yokufumana idatha kunye ne-tracet-gestrives esebenzayo kumaziko edatha iqhubekile kuphuhliso lwe-compact ephezuluIimodyuli ze-Optical. Itekhnoloji ye-Silicon esekwe kwitekhnoloji ye-Optoectroniki (i-SIP) iba yiqonga elithembisayo lokudibanisa izinto ezahlukeneyo zesifo se-Photoniic kwi-chip enye, evumela izisombululo zecawe kunye nezisombululo ezinobuchule. Eli nqaku liza kuphonononga i-noves i-noves I-IQon IQ Modlilator esekwe kwi-Gesi Eams, enokusebenza rhoqo kwi-75 gbaud.
Uyilo lwesixhobo kunye neempawu
Imodyuli ye-IQ ecetywayo yamkela i-compact 3 ye-compact engalweni, njengoko kubonisiwe kumzobo 1 (a). Ukudityaniswa kwe-Gesi Eam kunye ne-Termo Opriches Shifters Shifters, yamkela ukuqulunqwa kwesiNgesi. Ukukhanya kwegalelo kudityaniswe kwi-chip ngokusebenzisa isibini sokuTshintsha (i-GC) kunye nokuhlulwahlulwahlulwahlulahlula iindlela ezintathu nge-1 × 3 i-Mulfrometer (MMI). Emva kokudlula kwimodyuli kunye nesigaba seShifter, ukukhanya kuyamkeleka kwenye i-1 × 3 MMI kwaye emva koko kudityaniswe kwi-fiber ye-fiber enye (i-SSMF).
Umzobo 1: (a) Imifanekiso yeMicroscopic ye-IQ modulator; . . . Njengoko kubonisiwe kuMfanekiso 1 (b), uGesi Eam unebhendi ye-electro optiz. Umzobo 1 (b) Ukulinganisa iparamitha ye-S21 ye-Gessi ye-Gessi Eam usebenzisa i-67 GHZ Onner Amanani 1
Njengoko kubonisiwe kuMfanekiso 1 (e), eyona nto iphambili koluyilo kukukwazi ukucinezela abathwali bokwakhetha ngokuhlengahlengiswa kwenqanaba elidityanisiweyo kwingalo ephakathi. Umahluko wesigaba phakathi kwengalo ephezulu nezantsi yi-π / 2, isetyenziselwe ukuntywila okuntsonkothileyo, ngelixa umahluko wesigaba phakathi kwengalo ephakathi ngu -3 π / 4. Olu hlengahlengiso luvumela ukuphazamiseka okutshabalalisayo kumphathi, njengoko kubonisiwe kwindiza enobunzima bomzobo 1 (f).
Ukuseta uvavanyo kunye neziphumo
Iseti yesantya esiphezulu esiphezulu siboniswe kumzobo 2 (a). I-generatory ye-generary (i-keysight M8194A) isetyenziswa njengomthombo womqondiso, kwaye i-60 ye-60 GHZ i-60 GHZ i-Amples ye-RF Amplified (ngee-tees ezihlanganisiweyo) zisetyenziswa njengabaqhubi be-modulator. I-Bias Voltage ye-Gesi Eam ye-Tesi Ewe -2.5 v, kwaye intambo yenqanaba le-RF isetyenziselwa ukunciphisa ukunciphisa umbane kwinqanaba le-I kunye ne-q kunye ne-qats.
Umzobo 2: (a) Ukuseta okuphezulu kwesantya, (b) Ukucinezelwa kwenkathalo kwi-70 GBAUD, (c) Inqanaba lempazamo kunye nenqanaba ledatha, (d) kwi-70 gbaud. Sebenzisa i-lever yangaphandle ye-cavity (i-ECL) ene-100 khz, wavelethth ye-1555 NM, kunye namandla e-12 ye-DBM njengomsitho ophantsi. Emva kwemodyuli, uphawu lokukhanya luphakanyiwe usebenzisa iI-erbium-doped amplifier(E-Edfa) ukuhlawula i-intanethi ilahleko yelahleko kunye nelahleko yokufakwa kwe-modlilator.
Ekufumaneni isiphelo, i-chactrum ye-Optical (OSA) ibeka iliso kwi-spectrium of spectrium kunye nengcinezelo ye-8 (b) ye-70 Gbaud Sys. Sebenzisa umamkeli ophakathi wokudibana ukuze afumane imiqondiso, equka umxube ophethwe ngama-90 kunye nesineI-40 GHZ ilungelelene imifanekiso, kwaye uqhagamshelwe kwi-33 GHZ, i-GSA / i-GSA ye-GSA yokwenyani ye-Oscilloscope (RTO) (i-KOYSIEMIODD634A). Umthombo wesibini we-ECL one-100 khz isetyenziswa njenge-oscillator yendawo (LO). Ngenxa yendawo yokudlulisela isebenza phantsi kweemeko zokugcwala kwetyholo, kuphela amajelo amabini e-elektroniki asetyenziselwa ukuguqulwa kwe-analog-ukuya kwi-didital (i-ADC). Idatha irekhodwa kwi-RTO kwaye isebenze ukusebenzisa iprosesa yeDiredital yeDijithali yeDijithali (i-DSP).
Njengoko kubonisiwe kuMfanekiso 2 (c), umthambo we-IQ wavavanywa usebenzisa ifomathi ye-QPSK yemodyuli ukusuka kwi-40 Gbaud ukuya kwi-75 gbaud. Iziphumo zibonisa ukuba phantsi kwe-7% yezigqibo ezinzima zokulungiswa kwempazamo (i-HD-FEC), ireyithi inokufikelela kwi-140 GB / S; Ngaphantsi kwemeko ye-20% yesigqibo esithambileyo sokulungiswa kwempazamo (SD-FEC), isantya sinokufikelela kwi-150 GB / s. Umzobo we-Consterath kwi-70 Gbaud iboniswe kumzobo 2 (d). Isiphumo sinqunyelwe yi-OSCICCOCOPE bandwidth ye-33 GHZ, elingana ne-bandwidth ye-66 gbaud.
Njengoko kubonisiwe kumzobo 2 (b), isakhiwo esingaqhelekanga sengalo sinokucinezela ngokufanelekileyo ii-carriers ngereyithi evutha ngaphezulu kwe-30 db. Olu lwakhiwo alufuni ukucinezelwa ngokupheleleyo komthwali kwaye kungasetyenziselwa ukufumana abamkeli abafuna ukutshata ukuze ufumane imiqondiso, njenge-kramer kromer kronug (kk). Umphathi unokuhlengahlengiswa ngenqanaba lengalo eliphakathi lokutshintsha ukuthwala umthwalo onqwenelekayo kumyinge wecala (CSR).
Izibonelelo kunye nokuSebenza
Xa kuthelekiswa ne-leath yendande ye-lehnder (Iimodyuli ze-MZM) Namanye amabala e-Silicon-esekwe kwi-Aptoectronic ye-IQ, i-Silicon IQ Moddulator ineenzuzo ezininzi. Okokuqala, iyacaca ngobukhulu, ngaphezulu kwamaxesha ali-10 amancinci kune-IQ iimodyulitors ezenzelweImodyuli ye-Mach Zehinder. Okwesibini, uyilo olubekiweyo lwe-electrode aludingi ukusetyenziswa kwezinto zokuzibaza, ngaloo ndlela kuncitshiswa kwezakhono zokufumana izixhobo kunye namandla nganye nganye. Okwesithathu, amandla othintelo oluqhelekileyo ukwandisa ukuncitshiswa kwamandla okusasaza, ukuphucula ngakumbi ukusebenza kwamandla.
Ukongeza, i-bandwidth ye-gesi eam ibanzi kakhulu (i-30 i-30 i-30 i-nanometers), isuse imfuno ye-Microlnel Presments kwi-Microlnel Presvers kunye ne-Prossars ukuze ilungelelanise i-microwave moddiators (i-MRMs), yenza lula uyilo.
Le modyuli ye-compact kunye nemodyuli efanelekileyo ye-IQ ilungele kakhulu isizukulwana, inani eliphezulu lokubalwa, kunye nokuThululwa kweKholeji enamaziko amancinci kumaziko edatha, enika amandla aphezulu kunye nokunxibelelana okungakumbi kunxibelelwano olufanelekileyo.
Umphathi ocinezelweyo I-Silicon IQ Modlilator ubonakalisa intsebenzo egqwesileyo, kunye nenqanaba lokudluliselwa kwedatha ukuya kuthi ga kwi-150 GB / s engaphantsi kweemeko ezingama-20% ze-sd. Isakhiwo sayo esingalweni esi-3 esisekwe kwi-Gesi Eam sinezibonelelo ezibalulekileyo ngokwemigaqo, ukusebenza kakuhle kunye nokuyila ngokulula. Lo mthambo unokukwazi ukucinezela okanye uhlengahlengise umphangi ophembekileyo kwaye unokudityaniswa ngokufunyanwa kwesikitho kunye neKramer Kk) (KK) (KK) (KK) (KK) lwe-Tracet Compaints. Impumelelo eboniswayo iqhubela phambili ukufezekiswa kwe-Transcelives edityanisiweyo nefanelekileyo yokufikelela kwimfuno yokukhula kwedatha yedatha ephezulu kumaziko edatha kunye namanye amasimi.
