Kev tshuaj xyuas lub hauv paus ntsiab lus ntawm photoelectric moduleMach Zehnder modulator
Ua ntej, lub tswv yim yooj yim ntawm Mach Zehnder modulator
Mach-Zehnder modulator yog ib qho optical modulator siv los hloov cov teeb liab hluav taws xob mus rau hauv cov teeb liab optical. Nws txoj cai ua haujlwm yog raws li cov nyhuv electro-optical, los ntawm lub teb hluav taws xob los tswj cov ntsuas refractive ntawm lub teeb hauv nruab nrab kom ua tiav lub teeb modulation, yog faib lub teeb nkag mus rau hauv ob lub teeb liab sib npaug rau hauv ob ceg optical ntawm modulator.
Cov ntaub ntawv siv rau hauv ob ceg optical no yog cov ntaub ntawv electro-optical, uas nws cov refractive index sib txawv nrog qhov loj ntawm lub teeb liab hluav taws xob sab nraud. Txij li thaum qhov kev hloov pauv refractive index ntawm ceg optical yuav ua rau qhov hloov pauv theem ntawm lub teeb liab, thaum qhov kawg ntawm ob ceg teeb liab modulator tau sib koom ua ke dua, lub teeb liab synthesized optical yuav yog lub teeb liab cuam tshuam nrog kev hloov pauv ntawm qhov muaj zog, uas yog sib npaug rau kev hloov pauv ntawm lub teeb liab hluav taws xob mus rau hauv kev hloov pauv ntawm lub teeb liab optical, thiab paub txog kev hloov pauv ntawm lub teeb ci. Hauv ntej, lub modulator tuaj yeem paub txog kev hloov pauv ntawm ntau sab bands los ntawm kev tswj nws lub zog bias.
Qhov thib ob, lub luag haujlwm ntawmMach-Zehnder modulator
Mach-Zehnder modulator feem ntau yog siv rau hauvkev sib txuas lus fiber ntauthiab lwm yam teb. Hauv kev sib txuas lus fiber optic, cov teeb liab digital yuav tsum tau hloov mus ua cov teeb liab optical rau kev xa xov, thiab Machzender modulators tuaj yeem hloov cov teeb liab hluav taws xob mus ua cov teeb liab optical. Nws lub luag haujlwm yog ua kom muaj kev xa xov ceev thiab zoo hauv cov kab ke sib txuas lus fiber ntau.
Lub Mach Zehnder modulator kuj tseem siv tau rau kev tshawb fawb sim hauv thaj chaw ntawmkev siv hluav taws xob optoelectronicsPiv txwv li, nws siv tau los ua cov teeb pom kev zoo sib xws thiab siv cov haujlwm ib leeg-photon.
Qhov thib peb, cov yam ntxwv ntawm Mach Zehnder modulator
1. Mach Zehnder modulator tuaj yeem hloov cov teeb liab hluav taws xob mus rau hauv cov teeb liab kho qhov muag kom ua tiav kev xa xov ceev ceev, zoo.
2. Thaum lub modulator ua haujlwm, nws yuav tsum tau siv nrog lwm yam khoom siv xws li lub teeb pom kev zoo, lub teeb ntes, thiab lwm yam, los tsim kom muaj kev sib txuas lus fiber ntau tiav.
3. Mach Zehnder modulator muaj cov yam ntxwv ntawm kev teb ceev ceev thiab kev siv hluav taws xob tsawg, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev sib txuas lus ceev ceev.
Xaus Lus
Mach Zehnder modulator yog ib qhocov khoom siv kho qhov muagsiv los hloov lub teeb liab hluav taws xob mus ua lub teeb liab kho qhov muag. Nws lub luag haujlwm yog ua kom muaj kev xa xov hluav taws xob ceev thiab zoo hauv thaj chaw xws li kev sib txuas lus fiber ntau. Mach zender modulator muaj cov yam ntxwv ntawm kev teb sai thiab kev siv hluav taws xob tsawg, thiab yog ib qho ntawm cov khoom siv tseem ceeb hauv kev sib txuas lus fiber ntau.
