Isetyenziswa njani iImodyuli ye-EO
Emva kokufumana i-modulator ye-EO kunye nokuvula ipakethe, nceda ugqoke iiglavu ze-electrostatic / wristbands xa uchukumisa igobolondo yetyhubhu yentsimbi yesixhobo. Sebenzisa i-tweezers ukususa i-optical input/output port yesixhobo kwigrooves yebhokisi, uze ususe umzimba ongundoqo wemodyuli kwigrooves yesiponji. Emva koko ubambe umzimba oyintloko wemodyuli ye-EO ngesandla esinye kwaye utsale i-optical input/output port yemodyuli ngesinye.
Ukulungiswa kunye nokuhlolwa ngaphambi kokusetyenziswa
a. Qaphela ukuba akukho monakalo kumphezulu wemveliso, umphezulu wemodyuli kunye nomkhono wefiber optical.
b. Khangela ukuba ileyibhile ayinabumdaka na kwaye iimpawu zokuprinta zesilika-screen zicacile.
c. I-flange yombane ayonakaliswa kwaye zonke izikhonkwane ze-electrode zikhuselekile.
d. Sebenzisa i-fiber optical end face detector ukujonga ukuba iintsinga zamehlo kuzo zombini iziphelo zicocekile.
1. Amanyathelo okusetyenziswaimodyuli yokuqina
a. Jonga ukuba isiphelo sobuso begalelo / imveliso yefiber ebonakalayo yemodyuli yokuqina icocekile. Ukuba kukho amabala, nceda uzisule ngotywala.
b. I-intensite modulator ligalelo lokugcina i-polarization. Kunconywa ukusebenzisa i-polarization-ukugcina umthombo wokukhanya xa usetyenziswa (ubude bokukhanya bomthombo wokukhanya buxhomekeke kwi-wavelength esebenzayo ye-modulator), kwaye amandla okukhanya omthombo wokukhanya akhethwa yi-10dBm.
Xa usebenzisa i-modulator yamandla, qhagamshela umbane wombane we-GND kwi-pin 1 ye-modulator, kunye ne-terminal efanelekileyo yonikezelo lwamandla kwi-pin 2. I-Pin 3/4 yi-cathode kunye ne-anode ye-PD ngaphakathi kwe-modulator. Ukuba ufuna ukuyisebenzisa, nceda usebenzise le PD kunye nesekethe yokufumana ngasemva, kwaye le PD ingasetyenziselwa ngaphandle kokusebenzisa i-voltage (ukuba imodyuli ayinayo iPD yangaphakathi, i-pin 3/4 yi-NC, i-pin emisiwe).
d. Izinto eziphathekayo zemodyuli yokuqina yi-lithium niobate. Xa intsimi yombane isetyenziswe, isalathisi se-refractive se-crystal siya kutshintsha. Ngoko ke, xa i-voltage isetyenziswe kwi-modulator, ukulahleka kokufakwa kwe-modulator kuya kuhluka kunye nombane osetyenzisiweyo. Abasebenzisi banokulawula imodyuli kwindawo ethile yokusebenza ngokusetyenziswa kwabo.
Ukulumkela
a. Igalelo le-optical input yemodyuli mayingagqithi ixabiso lolungelelwaniso kwiphepha lovavanyo; ngaphandle koko, imodyuli iya konakaliswa.
b. Igalelo le-RF lemodyuli kufuneka lingagqithi ixabiso elilinganisiweyo kwiphepha lovavanyo; ngaphandle koko, imodyuli iya konakaliswa.
c. I-voltage eyongezelelweyo ye-modulator bias voltage pin yi-≤± 15V
2. Amanyathelo okusebenzisa iimodyuli yesigaba
a. Jonga ukuba isiphelo sobuso begalelo / imveliso yefiber ebonakalayo yemodyuli yokuqina icocekile. Ukuba kukho amabala, nceda uzisule ngotywala.
b. I-modulator yesigaba yi-polarization-ukugcina igalelo. Kunconywa ukusebenzisa i-polarization-ukugcina umthombo wokukhanya xa usetyenziswa (ubude bokukhanya bomthombo wokukhanya buxhomekeke kwi-wavelength esebenzayo ye-modulator), kwaye amandla okukhanya omthombo wokukhanya akhethwa yi-10dBm.
c. Xa usebenzisa imodyuli yesigaba, qhagamshela isignali yeRF kwizibuko le-RF yokufaka imodyuli.
d. Imodyuli yesigaba inokusebenza emva kokongeza isignali yerediyo, ukugqiba isigabaimodyuli ye-electro-optic. Isibane esimodareyithiweyo asinakubonwa ngokuthe ngqo sisikhangeli sefoto njengophawu lwefrikhwensi yerediyo emodareyithiweyo. Ngokuqhelekileyo, i-interferometer idinga ukusekwa, kwaye isignali yefrikhwensi yerediyo inokubonwa kuphela yi-photodetector emva kokuphazamiseka.
Ukulumkela
a. Igalelo le-optical input yemodyuli ye-EO mayingagqithi ixabiso lokulinganisa kwiphepha lovavanyo; ngaphandle koko, imodyuli iya konakaliswa.
b. Igalelo le-RF yemodyuli ye-EO mayingagqithi kwixabiso elilinganisiweyo kwiphepha lovavanyo; ngaphandle koko, imodyuli iya konakaliswa.
c. Xa useka i-interferometer, kukho iimfuno eziphezulu zokusetyenziswa kwendawo. Ukushukuma kokusingqongileyo kunye ne-fiber optical swaying kunokuchaphazela zombini iziphumo zovavanyo.
