Indlela yokusebenzisa i-I-EO module
Ngemva kokuthola i-modulator ye-EO nokuvula iphakheji, sicela ugqoke amagilavu/amabhande asehlakaleni e-electrostatic lapho uthinta ingxenye yegobolondo leshubhu lensimbi yedivayisi. Sebenzisa ama-tweezers ukuze ukhiphe ama-optical input/output port of the device kusukela ku-grooves yebhokisi, bese ukhipha indikimba eyinhloko yemoduli ezingotsheni zesipontshi. Bese ubamba umzimba oyinhloko wemodeli ye-EO ngesandla esisodwa bese uhudula imbobo yokufaka yokubona/yokukhiphayo yemoduli ngesinye.
Ukulungiselela nokuhlolwa ngaphambi kokusetshenziswa
a. Qaphela ukuthi akukho monakalo endaweni yomkhiqizo, ingaphezulu lemojuli kanye nomkhono wefiber optical.
b. Hlola ukuthi ilebula ayinalo ukungcola nokuthi izimpawu zokuphrinta zesikrini sikasilika zicacile.
c. I-flange kagesi ayilimele futhi zonke izikhonkwane ze-electrode ziphelele.
d. Sebenzisa i-optical fibre end face detector ukuze uhlole ukuthi imicu yokubona emikhawulweni yomibili ihlanzekile yini.
1. Izinyathelo zokusebenzisaintensity modulator
a. Hlola ukuthi ingabe ubuso besiphetho semicu ye-optical input/output yemoduli yokuqina buhlanzekile. Uma kukhona amabala, sicela usule ngotshwala.
b. I-intensity modulator iwukufaka kwe-polarization-maintaining. Kunconywa ukusebenzisa umthombo wokukhanya ogcina i-polarization uma usetshenziswa (ubude beza beza bomthombo wokukhanya buncike kubude beza obusebenzayo bemoduli), futhi amandla okukhanya omthombo wokukhanya anconyelwa ukuba ngu-10dBm.
Uma usebenzisa imodeli yamandla, xhuma isinikezeli samandla se-GND ukuze uphine u-1 wemojuli, kanye netheminali ephozithivu yesinikezeli samandla ukuze uphine u-2. Iphinikhodi engu-3/4 i-cathode ne-anode ye-PD ngaphakathi kwesimodeli. Uma udinga ukuyisebenzisa, sicela usebenzise le PD nesekhethi yokutholwa ngemuva, futhi le PD ingasetshenziswa ngaphandle kokusebenzisa i-voltage (uma imoduli ingenayo i-PD yangaphakathi, iphinikhodi 3/4 i-NC, iphinikhodi emisiwe).
d. Impahla ye-intensity modulator yi-lithium niobate. Lapho kusetshenziswa inkambu kagesi, inkomba ye-refractive ye-crystal izoshintsha. Ngakho-ke, lapho i-voltage isetshenziswa ku-modulator, ukulahlekelwa kokufaka kwe-modulator kuzohluka nge-voltage esetshenzisiwe. Abasebenzisi bangalawula imodyuli endaweni ethile yokusebenza ngokuya ngokusetshenziswa kwayo.
Izinyathelo zokuzivikela
a. Okokufaka kokubona kwemoduli akumele kudlule inani lokulinganisa eshidini lokuhlola; uma kungenjalo, i-modulator izolimala.
b. Okokufaka kwe-RF kwemoduli akumele kudlule inani elilinganiselwe eshidini lokuhlola; uma kungenjalo, i-modulator izolimala.
c. I-voltage eyengeziwe yephinikhodi ye-modulator bias voltage ingu-≤±15V
2. Izinyathelo zokusebenzisa i-i-modulator yesigaba
a. Hlola ukuthi ingabe ubuso besiphetho semicu ye-optical input/output yemoduli yokuqina buhlanzekile. Uma kukhona amabala, sicela usule ngotshwala.
b. I-modulator yesigaba iwukufaka kwe-polarization-ukugcina. Kunconywa ukusebenzisa umthombo wokukhanya ogcina i-polarization uma usetshenziswa (ubude beza beza bomthombo wokukhanya buncike kubude beza obusebenzayo bemoduli), futhi amandla okukhanya omthombo wokukhanya anconyelwa ukuba ngu-10dBm.
c. Uma usebenzisa imodulator yesigaba, xhuma isignali ye-RF embobeni yokufaka ye-RF yesimodeli.
d. I-modulator yesigaba ingasebenza ngemva kokwengeza isignali yefrikhwensi yomsakazo, ukuqedela isigabai-electro-optic module. Ukukhanya okushintshiwe akukwazi ukutholwa ngokuqondile yisithwebuli sezithombe njengesignali yefrikhwensi yomsakazo eshintshiwe. Ngokuvamile, i-interferometer idinga ukusethwa, futhi isignali yefrikhwensi yomsakazo ingatholwa kuphela yi-photodetector ngemva kokuphazanyiswa.
Izinyathelo zokuzivikela
a. Okokufaka okubonakalayo kwemoduli ye-EO akumele kudlule inani lokulinganisa eshidini lokuhlola; uma kungenjalo, i-modulator izolimala.
b. Okokufaka kwe-RF kwemoduli ye-EO akumele kudlule inani elilinganiselwe eshidini lokuhlola; uma kungenjalo, i-modulator izolimala.
c. Lapho usetha i-interferometer, kunezidingo eziphakeme kakhulu zemvelo yokusetshenziswa. Ukunyakaziswa kwemvelo kanye nokunyakaziswa kwe-fiber optical kungathinta kokubili imiphumela yokuhlolwa.
