Iskimu sendlela yokuthambeka ngokusekwe kwi-MZM Mocull

Iskimu sendlela yokuphuma rhoqo esekweImodyuli ye-MZM

Ukusasazeka kwendlela yokuhamba nge-optical kunokusetyenziswa njenge-lidarUmthombo wokukhanyaUkukhupha ngaxeshanye kwaye uskene kwiindlela ezahlukeneyo, kwaye kunokusetyenziswa njenge-Multi-Wavedth njengomthombo wokukhanya kwe-800g Fr4, ukuphelisa ukwakhiwa kwe-muxr. Ngokwesiqhelo, umthombo wokukhanya omnandi ngamandla aphantsi okanye akafakwanga kakuhle, kwaye zininzi iingxaki. Le nkqubo iswe namhlanje ineenzuzo ezininzi kwaye ingadluliselwa kwireferensi. Isakhiwo sesakhiwo siboniswa ngolu hlobo lulandelayo: amandla aphezuluI-DFB LaserUmthombo wokukhanya u-cw ukukhanya kwendawo yendawo kunye ne-wavelength enye kwi-frequency. Emva kokudlula kwiI-MUDLALOTORNgoluhlu oluthile lwemodyuli yemodyuli, i-Delufband iya kuveliswa, kwaye indawo yokuphumla esecaleni yimodyuli yemodyuli. I-MODMIlatotor isebenzisa i-LNOI ye-LNOI nge-8.2mm, njengoko kubonisiwe kwi-B. Emva kwecandelo elide lamandla amakhuluImodyuli yeSigaba, I-Prouqute yeModyuli ikwa-Frf, kunye nesigaba sayo kufuneka senze i-crest okanye i-roumple yophawu lwe-RF kunye nokukhanya komqondiso omnye komnye, okukhokelela kumazinyo aphezulu. I-DC Bias kunye neMpuma kubunzulu beMpuzi inokuchaphazela ukungathobeki kwe-frequency.

Ngokwemgangatho, umqondiso emva kwentsimi yokukhanya iphoxekile yiMpuzi yile:
Ingabonwa ukuba intsimi yokuphuma kwemveliso sisisasazi se-frequency enethuba le-WRF, kwaye ubukhulu bezandla zokusasazwa kwe-frequency zihambelana namandla e-DFB ahambelana namandla e-DFB ahambelana namandla e-DFB. Ngokulinganisa ukuqina kokukhanya kudlula kwimodyuli ye-MZM kwayeImo yesigaba seMpumi ye-PM, kwaye ke fft, i-fft, i-Special Special Speidrim ifunyenwe. Eli nani lilandelayo libonisa ubudlelwane ngokuthe ngqo phakathi kwe-frequency flow kunye nemodyuli ye-DC bias kunye nemodyuli kubunzulu bemifanekiso.

Eli nani lilandelayo libonisa umzobo wemizobo ebhalwe kwi-mzm bias dc ye-0.6π nemodyuli yobunzulu be-0.4π, ebonisa ukuba i-velogy yayo iphantsi kwe-velofs yayo yi- <5db.

Oku kulandelayo ngumzobo wephakheji ye-MZM Moddulator, ln yi-500m ingu-500m, ubunzulu be-etching yi-260NM, kunye nobubanzi be-Wapeguide yi-1.5um. Ubungqingqwa be-electrod yegolide yi-1.2um. Ubungqingqwa be-garding se-valing sio2 yi-2m.

Oku kulandelayo yindawo evavanyiweyo ye-OCC, enezinyo eli-13 ngokuthe ngqo kunye neflethi <2.4DB. I-Prouqute yeModyuli yi-5GHz, kunye neRF amandla elayisha kwi-MZM kunye ne-PM yi-11.24 i-DBM kunye ne-24.96DBM ngokulandelelana. Inani lamazinyo okusasazeka ngokusasazwayo anokwandiswa ngokuqhubeka nokwandisa ngakumbi amandla e-PM-RF, kunye nexesha lokusasazeka ngokusasaza lingandiswa ngokwandisa iModuquvel Rurest. umfanekiso
Oku kungasentla kusekwe kwiNkqubo ye-LNOI, kwaye oku kulandelayo kusekwe kwiskimu se-2. Umzobo wesakhiwo ngolu hlobo lulandelayo: I-chip idibanisa i-DBR Laser, i-MZM Mordulator, iMpumi yeMpuzi yeMpumelelo, iSOA kunye ne-SSC. I-chip enye inokufezekisa intsebenzo ephezulu yokuphuma.

I-SMSR ye-DBR Laser yi-35DB, ububanzi bomgca yi-38Mhz, kunye noluhlu lwentengo yi-9nm.

Imodyuli ye-MZM isetyenziselwa ukuvelisa i-Deadeband ngobude be-1mm kunye nebhendi ye-7GHz @ 3DB. Ubukhulu becala unqongophele ngokuziphatha okuphezulu, ilahleko yokukhanya ukuya kwi-20db @ -8b bias

Ubude be-SOA buyi-500μ1, esetyenziselwa ukubuyisa ilahleko yokulahleka kwemozulu, kunye nebhendi ebonakalayo yi-62nm @ 3DB @ 90MA. I-SSC edityanisiweyo kwimveliso iphucula ukusebenza ngempumelelo kwe-chip (ukusebenza kakuhle kwe-5db). Amandla okukhupha yokugqibela makamalunga -7dbm.

Ukuze kuveliswe ukusasazeka kwe-frequency, i-RF yemodyuli esetyenzisiweyo yi-2.6ghz, amandla yi-24.7dbm, kunye ne-VPI yeModyuli yesigaba yi-5V. Umzobo ongezantsi sisiphumo se-tetophobic esikhokelela kwi-Stonectum ene-17 yeefolphobic @ 10DB kunye ne-snsr ephezulu kune-30db.

Iskimu senzelwe ukosulelwa kwe-5G microwave, kwaye eli nani lilandelayo licandelo elibonakalayo lifunyenwe ngumthombo wokukhanya, onokuthi avelise imiqondiso ye-26g ngamaxesha ali-10. Ayichazwanga apha.

Kwisishwankathelo, isiseko sexesha elibonakalayo esiveliswe yile ndlela sinethuba lokuphumla ngokuzinzileyo, ingxolo ephantsi yenqanaba, amandla aphezulu kunye nokudityaniswa ngokulula, kodwa zininzi iingxaki. I-RF igcwele i-PM kwi-PM ifuna amandla amakhulu, inyathelo elikhulu laMandla, kwaye ithutyana lokuphumla lilinganiselwe ngumgangatho wemodyuli, ukuya kuthi ga kwi-50gz, efuna i-10GHz, ifuna i-10NGZ System kwiNkqubo ye-FR8. Ukusetyenziswa okuncinci, ukungcola kwamandla akwanele.
