Ukuguqulwa kwe-Optical ukwengeza ulwazi ku-wave light wave, ukuze ipharamitha ethile ye-carrier light wave ishintshe ngokushintsha kwesignali yangaphandle, kuhlanganise nobukhulu begagasi lokukhanya, isigaba, imvamisa, i-polarization, ubude be-wavelength njalonjalo.Igagasi lokukhanya elishintshiwe elithwala ulwazi lidluliselwa ku-fiber, litholwa umtshina wesithombe, bese likhipha imininingwane edingekayo.
Isisekelo esingokomzimba sokushintshwa kwe-electro-optic umphumela we-electro-optic, okungukuthi, ngaphansi kwesenzo senkundla kagesi esetshenzisiwe, inkomba ye-refractive yamanye amakristalu izoshintsha, futhi lapho igagasi lokukhanya lidlula kule ndlela, izici zayo zokudlulisela zizoshintsha. bathinteke futhi bashintshwe.
Kunezinhlobo eziningi ze-electro-optic modulators(EO modulator), ezingahlukaniswa izigaba ezahlukene ngokwamazinga ahlukene.
Ngokuya ngesakhiwo esihlukile se-electrode, i-EOM ingahlukaniswa ibe imoduli yepharamitha egayiwe kanye nemoduli yamagagasi okuhamba.
Ngokuya ngesakhiwo esihlukile se-waveguide, i-EOIM ingahlukaniswa ibe yimoduli ye-Msch-Zehnder interference intensity kanye nemoduli yokuqina yokuhlanganisa.
Ngokuhambisana nobudlelwano phakathi kokuqondiswa kokukhanya kanye nesiqondiso senkundla kagesi, i-EOM ingahlukaniswa ngamamojula welongitudinal namamojula aguquguqukayo.I-longitudinal electro-optic modulator inezinzuzo zesakhiwo esilula, ukusebenza okuzinzile (okuzimele kwe-polarization), akukho birefringence yemvelo, njll. Ububi bayo ukuthi i-voltage ye-half-wave iphezulu kakhulu, ikakhulukazi uma i-modulation frequency iphezulu, amandla. ukulahlekelwa kukhulu uma kuqhathaniswa.
I-Electro-optical intensity modulator ingumkhiqizo odidiyelwe kakhulu ophethwe yi-Rofea onamalungelo azimele empahla yobuhlakani.Ithuluzi lihlanganisa i-electro-optical intensity modulator, i-microwave amplifier kanye nesekethe yayo yokushayela ibe yinye, engagcini nje ngokusiza ukusetshenziswa kwabasebenzisi, kodwa futhi ithuthukisa kakhulu ukwethembeka kwe-MZ intensity modulator, futhi ingahlinzeka ngezinsizakalo ezenziwe ngokwezifiso ngokuvumelana nezidingo zomsebenzisi.
