Optical modulation ndeyekuwedzera ruzivo kune inotakura light wave, kuitira kuti imwe parameter ye carrier light wave inoshanduka nekuchinja kwechiratidzo chekunze, kusanganisira kusimba kwechiedza chechiedza, chikamu, frequency, polarization, wavelength uye zvichingodaro.Iyo modulated light wave inotakura ruzivo inofambiswa mufiber, inowonekwa neiyo detector yemifananidzo, yobva yaburitsa ruzivo rwunodiwa.
Hwaro hwemuviri hwe electro-optic modulation ndeye electro-optic mhedzisiro, ndiko kuti, pasi pekuita kwenzvimbo yemagetsi yakaiswa, iyo refractive index yemamwe makristasi ichachinja, uye kana mwenje wave uchipfuura nepakati peiyi svikiro, hunhu hwayo hwekutapurirana huchachinja. kukanganiswa uye kuchinjwa.
Kune akawanda marudzi e electro-optic modulators (EO modulator), iyo inogona kupatsanurwa muzvikamu zvakasiyana zvichienderana nematanho akasiyana.
Zvinoenderana neyakasiyana magadzirirwo emagetsi, EOM inogona kukamurwa kuita lumped parameter modulator uye yekufamba-wave modulator.
Zvinoenderana neyakasiyana waveguide chimiro, EOIM inogona kukamurwa kuita Msch-Zehnder kupindira intensity modulator uye inotungamira yekubatanidza intensity modulator.
Zvinoenderana nehukama pakati pekutungamira kwechiedza uye kutungamira kwemunda wemagetsi, EOM inogona kukamurwa kuita longitudinal modulators uye transverse modulators.Iyo longitudinal electro-optic modulator ine zvakanakira chimiro chakareruka, yakagadzikana mashandiro (yakazvimirira polarization), hapana birefringence yepanyama, nezvimwewo. Yakashata yayo ndeyekuti iyo hafu-wave voltage yakawandisa, kunyanya kana iyo modulation frequency yakakwira, simba. kurasikirwa kwakakura.
Electro-optical intensity modulator chigadzirwa chakabatanidzwa zvakanyanya cheRofea chine kodzero dzakazvimirira dzepfuma.Icho chiridzwa chinobatanidza electro-optical intensity modulator, microwave amplifier uye dhiraivha yayo yekutyaira mune imwe, iyo isingafambisi chete kushandiswa kwevashandisi, asiwo inovandudza zvakanyanya kuvimbika kweMZ intensity modulator, uye inogona kupa masevhisi akagadziridzwa zvinoenderana nezvinodiwa nemushandisi.
