Uhlalutyo olusisiseko lwemodyuli ye-photoelectricImodulator kaMach Zehnder

Okokuqala, ingcamango esisiseko ye-modulator kaMach Zehnder

I-Mach-Zehnder modulator yi-optical modulator esetyenziselwa ukuguqula imiqondiso yombane ibe yimiqondiso ye-optical. Umgaqo wayo wokusebenza usekelwe kwisiphumo se-electro-optical, ngokusebenzisa intsimi yombane ukulawula i-refractive index yokukhanya kwi-medium ukuze kufezekiswe i-light modulation, kukwahlula ukukhanya okungenayo kube yimiqondiso emibini elinganayo kumasebe amabini e-optical e-modulator.
Izinto ezisetyenziswa kula masebe mabini e-optical zizinto ze-electro-optical, apho i-refractive index yazo iyahluka ngokobukhulu besignali yombane esetyenziswa ngaphandle. Ekubeni utshintsho lwe-refractive index yesebe le-optical luya kubangela utshintsho lwesigaba sesignali, xa isiphelo sesiphumo se-modulator yesignali yesebe ezimbini sidityanisiwe kwakhona, i-synthesized optical signal iya kuba yisignali yokuphazamiseka enotshintsho kubunzulu, olulingana nokuguqula utshintsho lwesignali yombane ibe lutshintsho lwesignali ye-optical, kunye nokuqonda ukuguqulwa kobunzulu bokukhanya. Ngamafutshane, i-modulator inokuqonda ukuguqulwa kweebhendi ezahlukeneyo zecala ngokulawula i-bias voltage yayo.

Okwesibini, indimaImodulator yeMach-Zehnder

I-modulator yeMach-Zehnder isetyenziswa kakhulu kwi-unxibelelwano lwefayibha ye-opticalkunye nezinye iinkalo. Kunxibelelwano lwe-fiber optic, iimpawu zedijithali kufuneka ziguqulwe zibe ziimpawu ezibonakalayo ukuze zidluliselwe, kwaye ii-modulators zeMachzender zinokuguqula iimpawu zombane zibe ziimpawu ezibonakalayo. Indima yazo kukufezekisa ukuhanjiswa kwesignali ngesantya esiphezulu nangomgangatho ophezulu kwiinkqubo zonxibelelwano lwe-fiber optical.

I-modulator yeMach Zehnder ingasetyenziselwa uphando oluvavanyiweyo kwicandelo le-i-optoelectronicsUmzekelo, ingasetyenziselwa ukwenza imithombo yokukhanya ehambelanayo kunye nokuphumeza imisebenzi ye-single-photon.

Okwesithathu, iimpawu zeMach Zehnder modulator

1. I-modulator yeMach Zehnder inokuguqula imiqondiso yombane ibe yimiqondiso ye-optical ukuze ifikelele ekudlulisweni kwesignali ngesantya esiphezulu, nomgangatho ophezulu.

2. Xa i-modulator isebenza, kufuneka isetyenziswe nezinye izixhobo ezifana nemithombo yokukhanya, izixhobo zokubona ukukhanya, njl.njl., ukuze kwenziwe inkqubo epheleleyo yonxibelelwano lwefayibha ye-optical.

3. I-modulator yeMach Zehnder ineempawu zesantya sokuphendula ngokukhawuleza kunye nokusetyenziswa kwamandla aphantsi, nto leyo enokuhlangabezana neemfuno zonxibelelwano olukhawulezayo.

【 Isiphelo】

I-modulator yeMach Zehnder yi-i-modulator yokukhanyaisetyenziselwa ukuguqula isignali yombane ibe sisignali yokukhanya. Indima yayo kukufezekisa ukuhanjiswa kwesignali ngesantya esiphezulu, nomgangatho ophezulu kwiindawo ezifana nonxibelelwano lwefayibha ye-optical. I-Mach zender modulator ineempawu zokuphendula ngokukhawuleza kunye nokusetyenziswa kwamandla aphantsi, kwaye yenye yezixhobo ezibalulekileyo kwinkqubo yonxibelelwano lwefayibha ye-optical.
