Ukuguqulwa kwe-optical kuwukwengeza ulwazi kugagasi lokukhanya lomthwali, ukuze ipharamitha ethile yegagasi lokukhanya lomthwali ishintshe ngokushintsha kwesignali yangaphandle, okuhlanganisa ukuqina kwegagasi lokukhanya, isigaba, imvamisa, i-polarization, ubude be-wavelength njalo njalo. Igagasi lokukhanya eliguquliwe eliphethe ulwazi lidluliselwa ku-fiber, litholwe yi-photo detector, bese likhipha ulwazi oludingekayo.
Isisekelo esingokoqobo sokuguqulwa kwe-electro-optic umphumela we-electro-optic, okungukuthi, ngaphansi kwesenzo sensimu kagesi esetshenzisiwe, inkomba yokukhanya kwamakristalu athile izoshintsha, futhi lapho igagasi lokukhanya lidlula kule ndlela, izici zalo zokudlulisela zizothinteka futhi zishintshwe.
Kunezinhlobo eziningi zama-electro-optic modulators (i-EO modulator), angahlukaniswa ngezigaba ezahlukene ngokwezindinganiso ezahlukene.
Ngokwesakhiwo se-electrode esihlukile, i-EOM ingahlukaniswa ibe yi-lumped parameter modulator kanye ne-traveling-wave modulator.
Ngokwesakhiwo esihlukile se-waveguide, i-EOIM ingahlukaniswa ibe yi-Msch-Zehnder interference intensity modulator kanye ne-directional coupling intensity modulator.
Ngokusho kobudlelwano phakathi kokuqondisa kokukhanya kanye nesiqondiso sensimu kagesi, i-EOM ingahlukaniswa ngama-modulators e-longitudinal kanye nama-transverse modulators. I-longitudinal electro-optic modulator inezinzuzo zesakhiwo esilula, ukusebenza okuzinzile (ngaphandle kwe-polarization), ukungabi ne-birefringence yemvelo, njll. Ububi bayo ukuthi i-half-wave voltage iphezulu kakhulu, ikakhulukazi lapho imvamisa yokuguquguquka iphezulu, ukulahleka kwamandla kukhulu kakhulu.
I-Electro-optical intensity modulator iwumkhiqizo ohlanganiswe kakhulu ophethwe yiRofea onamalungelo obunikazi obuzimele. Le thuluzi lihlanganisa i-electro-optical intensity modulator, i-microwave amplifier kanye ne-driving circuit yalo ibe yinye, okungagcini nje ngokwenza kube lula ukusetshenziswa kwabasebenzisi, kodwa futhi kuthuthukisa kakhulu ukuthembeka kwe-MZ intensity modulator, futhi linganikeza izinsizakalo ezenziwe ngokwezifiso ngokwezidingo zomsebenzisi.
