Ukumodareyithwa kwe-Optical kukongeza ulwazi kwi-carrier light wave, ukwenzela ukuba ipharamitha ethile ye-carrier light wave itshintsha kunye nokutshintsha kwesignali yangaphandle, kubandakanywa nobukhulu be-wave wave, isigaba, i-frequency, i-polarization, i-wavelength njalo njalo.Amaza okukhanya amodareyithiweyo athwele ulwazi agqithiselwa kwifayibha, afunyanwe sisikhangeli sefoto, emva koko akhuphe ulwazi olufunekayo.
Isiseko somzimba sokumodareyitha kwe-electro-optic yimpembelelo ye-electro-optic, oko kukuthi, phantsi kwesenzo sommandla wombane osetyenzisiweyo, isalathiso se-refractive samanye amakristale siya kutshintsha, kwaye xa i-wave yokukhanya idlula kule ndlela, iimpawu zayo zokuhambisa ziya kutshintsha. ukuchaphazeleka kwaye utshintshwe.
Kukho iintlobo ezininzi zeemodyuli ze-electro-optic (imodyuli ye-EO), enokwahlulwa ngokweendidi ezahlukeneyo ngokwemigangatho eyahlukeneyo.
Ngokwesakhiwo esahlukileyo se-electrode, i-EOM inokwahlulwa ibe yimodyuli yeparamitha elumped kunye nemodyuli yokuhamba-amaza.
Ngokolwakhiwo olwahlukileyo lwe-waveguide, i-EOIM inokohlulwa ibe yimodyuli ye-Msch-Zehnder yokuphazamiseka kokuphazamiseka kunye nemodyuli ehambelanayo yokudibanisa.
Ngokobudlelwane phakathi kolwalathiso lokukhanya kunye nolwalathiso lwentsimi yombane, i-EOM inokwahlulwa ibe ziimodareyitha ezinde kunye neemodyuli ezinqamlezileyo.I-modulator ye-electro-optic longitudinal ineenzuzo zesakhiwo esilula, ukusebenza okuzinzileyo (okuzimeleyo kwi-polarization), akukho birefringence yendalo, njl njl. Ukungalunganga kwayo kukuba i-half-wave voltage iphezulu kakhulu, ngakumbi xa i-modulation frequency iphezulu, amandla. ilahleko inkulu ngokwentelekiso.
Imodyuli ye-Electro-optical intensity yimveliso edityaniswe kakhulu ephethwe yiRofea enamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda.Isixhobo sidibanisa i-electro-optical intensity modulator, i-microwave amplifier kunye nesekethe yayo yokuqhuba ibe yinye, engaququzeleli kuphela ukusetyenziswa kwabasebenzisi, kodwa iphucula kakhulu ukuthembeka kwe-MZ intensity modulator, kwaye inokubonelela ngeenkonzo ezenziwe ngokwezifiso ngokweemfuno zomsebenzisi.
