Indlela yokusebenzisa i-EO modulator

Indlela yokusebenzisa i-Imodulator ye-EO

Emva kokufumana i-EO modulator nokuvula iphakheji, nceda unxibe iiglavu/iibhanti zesandla ezisebenza ngombane xa uchukumisa inxalenye yegobolondo lesinyithi lesixhobo. Sebenzisa ii-tweezers ukususa ii-optical input/output ports zesixhobo kwi-grooves yebhokisi, uze ususe umzimba oyintloko we-modulator kwi-sponge grooves. Emva koko ubambe umzimba oyintloko we-EO modulator ngesandla esinye uze urhuqe i-optical input/output port ye-modulator ngesinye.

Ukulungiswa kunye nokuhlolwa phambi kokusetyenziswa

a. Qaphela ukuba akukho monakalo kumphezulu wemveliso, kumphezulu wemodyuli kunye nesleeve yefayibha ye-optical.

b. Qinisekisa ukuba ileyibhile ayinangcola kwaye iimpawu zokuprinta zesikrini sesilika zicacile.

c. I-flange yombane ayonakalanga kwaye zonke izikhonkwane ze-electrode zilungile.

d. Sebenzisa isixhobo sokubona isiphelo sefayibha ye-optical ukujonga ukuba iifayibha ze-optical kuzo zombini iziphelo zicocekile na.

1. Amanyathelo okusebenzisaimodyuli yokuqina

a. Jonga ukuba imiphetho yeefayibha ze-optical zokufaka/zokukhupha ze-intensity modulator zicocekile na. Ukuba kukho amabala, nceda uwasule nge-alcohol.

b. I-intensive modulator yi-input yokugcina i-polarization. Kucetyiswa ukusebenzisa umthombo wokukhanya ogcina i-polarization xa usetyenziswa (ubude bomphezulu womthombo wokukhanya buxhomekeke kubude bomphezulu obusebenzayo be-modulator), kwaye amandla okukhanya omthombo wokukhanya angcono yi-10dBm.

Xa usebenzisa i-strength modulator, qhagamshela i-power supply GND kwi-pin 1 ye-modulator, kunye ne-positive terminal ye-power supply kwi-pin 2. I-Pin 3/4 yi-cathode kunye ne-anode ye-PD ngaphakathi kwi-modulator. Ukuba ufuna ukuyisebenzisa, nceda usebenzise le PD kunye ne-acquisition circuit ekupheleni ngasemva, kwaye le PD ingasetyenziswa ngaphandle kokusebenzisa i-voltage (ukuba i-modulator ayinayo i-PD yangaphakathi, i-pin 3/4 yi-NC, i-pin exhonyiweyo).

d. Izinto ezisetyenziswa kwi-intensity modulator yi-lithium niobate. Xa kusetyenziswa intsimi yombane, i-refractive index yekristale iya kutshintsha. Ke ngoko, xa kusetyenziswa i-voltage kwi-modulator, ukulahleka kokufakwa kwe-modulator kuya kwahluka ngokwe-voltage esetyenzisiweyo. Abasebenzisi banokulawula i-modulator kwindawo ethile yokusebenza ngokwendlela esetyenziswa ngayo.

Ukulumkela

a. Igalelo le-optical le-modulator akufuneki lidlule ixabiso lokulinganisa kwiphepha lovavanyo; kungenjalo, i-modulator iya konakala.

b. Igalelo le-RF le-modulator akufuneki lidlule ixabiso elilinganisiweyo kwiphepha lovavanyo; kungenjalo, i-modulator iya konakala.

c. I-voltage eyongezelelweyo yephini ye-voltage ye-modulator bias yi-≤±15V

2. Amanyathelo okusebenzisaimodyuli yesigaba

a. Jonga ukuba imiphetho yeefayibha ze-optical zokufaka/zokukhupha ze-intensity modulator zicocekile na. Ukuba kukho amabala, nceda uwasule nge-alcohol.

b. I-phase modulator yi-input yokugcina i-polarization. Kucetyiswa ukusebenzisa umthombo wokukhanya ogcina i-polarization xa usetyenziswa (ubude bomphezulu womthombo wokukhanya buxhomekeke kubude bomphezulu obusebenzayo be-modulator), kwaye amandla okukhanya omthombo wokukhanya angcono yi-10dBm.

c. Xa usebenzisa i-phase modulator, qhagamshela isignali ye-RF kwi-RF input port ye-modulator.

d. I-phase modulator ingasebenza emva kokongeza isignali yerediyo, igqibezele isigabai-electro-optic modulatorUkukhanya okuguquliweyo akunakufunyanwa ngokuthe ngqo yi-photodetector njengesignali yerediyo eguquliweyo. Ngokwesiqhelo, kufuneka kumiselwe i-interferometer, kwaye isignali yerediyo inokubonwa kuphela yi-photodetector emva kokuphazamiseka.

c. Xa useta i-interferometer, kukho iimfuno eziphezulu kakhulu kwindawo yokusetyenziswa. Ukushukuma kwendalo kunye nokushukuma kwefayibha ye-optical zombini zinokuchaphazela iziphumo zovavanyo.
