Indlela yokusebenzisa i-EO modulator

Indlela yokusebenzisa i-I-modulator ye-EO

Ngemva kokuthola i-EO modulator nokuvula iphakheji, sicela ugqoke amagilavu/amabhande esandla asebenza ngogesi uma uthinta ingxenye yegobolondo lensimbi yedivayisi. Sebenzisa ama-tweezers ukususa ama-optical input/output ports edivayisi emihumeni yebhokisi, bese ususa umzimba oyinhloko we-modulator emihumeni yesiponji. Bese ubamba umzimba oyinhloko we-EO modulator ngesandla esisodwa bese uhudula i-optical input/output port ye-modulator ngesinye.

Ukulungiselela nokuhlola ngaphambi kokusebenzisa

a. Qaphela ukuthi akukho monakalo ebusweni bomkhiqizo, ebusweni bemojuli kanye ne-sleeve ye-optical fiber.

b. Hlola ukuthi ilebula ayinawo ukungcola nokuthi izimpawu zokunyathelisa zesikrini sesilika zicacile.

c. I-flange kagesi ayonakalanga futhi zonke izikhonkwane ze-electrode ziphelele.

d. Sebenzisa isitholi sobuso se-optical fiber ukuze uhlole ukuthi imicu ye-optical kuzo zombili izinhlangothi ihlanzekile yini.

1. Izinyathelo zokusebenzisai-modulator yokuqina

a. Hlola ukuthi ubuso bokugcina bemicu yokukhanya yokufaka/yokukhipha ye-intensity modulator buhlanzekile yini. Uma kukhona amabala, sicela uwasule ngotshwala.

b. I-intensity modulator iyi-input egcina i-polarization. Kunconywa ukusebenzisa umthombo wokukhanya ogcina i-polarization uma usetshenziswa (ubude bomsuka wokukhanya buxhomeke kubude bomsuka obusebenzayo be-modulator), futhi amandla okukhanya omthombo wokukhanya kungcono abe yi-10dBm.

Uma usebenzisa i-power modulator, xhuma i-GND yokunikezwa kwamandla ku-pin 1 ye-modulator, kanye ne-terminal enhle yokunikezwa kwamandla ku-pin 2. I-Pin 3/4 iyi-cathode kanye ne-anode ye-PD ngaphakathi kwe-modulator. Uma udinga ukuyisebenzisa, sicela usebenzise le PD ngesekethe yokuthola ngemuva, futhi le PD ingasetshenziswa ngaphandle kokusebenzisa i-voltage (uma i-modulator ingenayo i-PD yangaphakathi, i-pin 3/4 iyi-NC, i-pin emisiwe).

d. Izinto ze-intensive modulator yi-lithium niobate. Uma kusetshenziswa insimu kagesi, inkomba yokukhanya kwekristalu izoshintsha. Ngakho-ke, uma kusetshenziswa i-voltage ku-modulator, ukulahlekelwa kokufakwa kwe-modulator kuzohluka nge-voltage esetshenzisiwe. Abasebenzisi bangalawula i-modulator endaweni ethile yokusebenza ngokuya ngokusetshenziswa kwayo.

Izinyathelo zokuzivikela

a. Okokufaka okubonakalayo kwe-modulator akumele kudlule inani lokulinganisa ephepheni lokuhlola; ngaphandle kwalokho, i-modulator izolimala.

b. Okufakwayo kwe-RF kwe-modulator akumele kudlule inani elilinganisiwe ephepheni lokuhlola; ngaphandle kwalokho, i-modulator izolimala.

c. I-voltage eyengeziwe yephini ye-voltage ye-modulator bias ingu-≤±15V

2. Izinyathelo zokusebenzisai-modulator yesigaba

a. Hlola ukuthi ubuso bokugcina bemicu yokukhanya yokufaka/yokukhipha ye-intensity modulator buhlanzekile yini. Uma kukhona amabala, sicela uwasule ngotshwala.

b. I-phase modulator iwukufakwa kokulondoloza i-polarization. Kunconywa ukusebenzisa umthombo wokukhanya okulondoloza i-polarization uma usetshenziswa (ubude bomsuka wokukhanya buxhomeke kubude bomsuka obusebenzayo be-modulator), futhi amandla okukhanya omthombo wokukhanya kungcono abe yi-10dBm.

c. Uma usebenzisa i-phase modulator, xhuma isignali ye-RF echwebeni lokufaka le-RF le-modulator.

d. I-phase modulator ingasebenza ngemva kokwengeza isignali yemvamisa yomsakazo, iqedele isigabai-electro-optic modulatorUkukhanya okuguquliwe akukwazi ukutholwa ngqo yi-photodetector njengesignali yemvamisa yomsakazo eguquliwe. Ngokuvamile, kudingeka kusethwe i-interferometer, futhi isignali yemvamisa yomsakazo ingatholwa kuphela yi-photodetector ngemva kokuphazamiseka.

Izinyathelo zokuzivikela

a. Okokufaka okubonakalayo kwe-modulator ye-EO akumele kudlule inani lokulinganisa ephepheni lokuhlola; ngaphandle kwalokho, i-modulator izolimala.

b. Ukufakwa kwe-RF kwe-modulator ye-EO akumele kudlule inani elilinganisiwe ephepheni lokuhlola; ngaphandle kwalokho, i-modulator izolimala.

c. Lapho usetha i-interferometer, kunezidingo eziphakeme kakhulu zendawo yokusetshenziswa. Ukushukuma kwemvelo kanye nokushukuma kwe-optical fiber kungathinta imiphumela yokuhlolwa.
