Uhlalutyo lomgaqo wemodyuli yefoto yombaneImodyuli kaMach Zehnder
Okokuqala, ingcamango esisiseko ye-Mach Zehnder imodyuli
Imodyuli yeMach-Zehnder sisimodareyitha sokukhanya esisetyenziselwa ukuguqula imiqondiso yombane ibe yimiqondiso yokukhanya. Umgaqo wayo wokusebenza usekelwe kwimpembelelo ye-electro-optical, ngokusebenzisa intsimi yombane yokulawula isalathisi sokukhanya sokukhanya phakathi ukufezekisa ukumodareyitha kokukhanya, kukwahlula ukukhanya kwegalelo kwiimpawu ezimbini ezilinganayo kumasebe amabini optical of the modulator.
Izinto ezisetyenzisiweyo kula masebe amabini optical zixhobo ze-electro-optical, i-index yayo ye-refractive index iyahluka kunye nobukhulu bomqondiso wombane osetyenziswa ngaphandle. Ekubeni utshintsho lwesalathiso lwe-refractive lwesebe le-optical luza kubangela utshintsho lwesigaba somqondiso, xa isiphelo sesiphumo se-modulator yesiginali yesebe ezimbini sidityanisiwe kwakhona, isignali ye-optical synthesized iya kuba yisignali yokuphazamiseka kunye noshintsho kubukhulu, obulingana nokuguqula. ukutshintshwa komqondiso wombane kwinguqu yesignali ye-optical, kunye nokuqonda ukumodareyitha kokukhanya kokukhanya. Ngamafutshane, imodareyitha inokuqonda ukumodareyithwa kweebhendi zamacala ahlukeneyo ngokulawula amandla ayo ombane wokuthambekela.
Okwesibini, indima yeImodyuli kaMach-Zehnder
Imodyuli yeMach-Zehnder isetyenziswa ikakhulu kwiunxibelelwano lwefiber opticalkunye neminye imimandla. Kunxibelelwano lwefiber optic, imiqondiso yedijithali kufuneka iguqulwe ibe yimiqondiso ye-optical yokuhanjiswa, kwaye iimodyuli zeMachzender zinokuguqula imiqondiso yombane ibe yimiqondiso ye-optical. Indima yayo kukufikelela kwisantya esiphezulu kunye nokuhanjiswa komgangatho ophezulu kwiinkqubo zonxibelelwano lwefiber optical.
Imodyuli ye-Mach Zehnder ingasetyenziselwa uphando lovavanyo kwintsimi yeoptoelectronics. Ngokomzekelo, ingasetyenziselwa ukwenza imithombo yokukhanya ehambelanayo kunye nokuphumeza imisebenzi ye-photon enye.
Okwesithathu, iimpawu ze-modulator ye-Mach Zehnder
1. Imodyuli ye-Mach Zehnder inokuguqula iimpawu zombane zibe yimiqondiso ye-optical ukuphumeza isantya esiphezulu, ukuhanjiswa kwesignali ephezulu.
2. Xa imodyuli isebenza, kufuneka isetyenziswe kunye nezinye izixhobo ezifana nemithombo yokukhanya, i-light detectors, njl., ukwenza inkqubo epheleleyo yonxibelelwano ye-fiber optical.
3. I-modulator ye-Mach Zehnder ineempawu zesantya sokuphendula ngokukhawuleza kunye nokusetyenziswa kwamandla aphantsi, onokuhlangabezana neemfuno zonxibelelwano olukhawulezayo.
【 Isiphelo 】
Imodyuli yeMach Zehnder yiimodyuli yokubonaisetyenziselwa ukuguqula umqondiso wombane ube ngumqondiso obonakalayo. Indima yayo kukufikelela kwisantya esiphezulu, ukuhanjiswa kweempawu ezikumgangatho ophezulu kwiindawo ezinjengonxibelelwano lwefiber optical. Imodyuli yeMach zender ineempawu zokuphendula ngokukhawuleza kunye nokusetyenziswa kwamandla aphantsi, kwaye yenye yezixhobo eziyimfuneko kwinkqubo yonxibelelwano lwefiber optical.
