Kev nkag siab zoo ntawm electro-optic modulators
Ib qho Electro-optic modulator (EOM) yog ib qho khoom siv hluav taws xob hluav taws xob uas siv hluav taws xob hluav taws xob los tswj cov teeb liab kho qhov muag, feem ntau yog siv rau hauv cov txheej txheem kho qhov muag hloov pauv hauv kev siv thev naus laus zis hauv kev sib txuas lus.
Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau electro-optic modulator:
1. Lub hauv paus ntsiab lus ntawm lubelectro-optic modulatoryog raws li cov nyhuv electro-optic, uas yog, lub refractive index ntawm ib co ntaub ntawv yuav hloov nyob rau hauv qhov kev txiav txim ntawm ib daim ntawv thov hluav taws xob teb. Raws li lub teeb nthwv dej dhau los ntawm cov khoom siv lead ua no, cov yam ntxwv nthuav tawm hloov pauv nrog cov hluav taws xob. Siv lub hauv paus ntsiab lus no, theem, amplitude lossis polarization xeev ntawm lubkho qhov muagteeb liab tuaj yeem tswj tau los ntawm kev hloov pauv cov ntawv thov hluav taws xob.
2. Cov qauv thiab muaj pes tsawg leeg Electro-optical modulators feem ntau yog tsim los ntawm optical paths, amplifiers, lim thiab photoelectric converters. Tsis tas li ntawd, nws suav nrog cov khoom tseem ceeb xws li cov tsav tsheb ceev, fiber ntau optical thiab piezoelectric crystals. Cov qauv ntawm electro-optic modulator tuaj yeem sib txawv raws li nws cov qauv kev hloov kho thiab cov ntawv thov, tab sis feem ntau suav nrog ob ntu: electro-optic inverter module thiab photoelectric modulation module.
3. Modulation hom Electro-optic modulator muaj ob hom kev hloov pauv loj:theem modulationthiab siv zog modulation. Phase modulation: Cov theem ntawm cov cab kuj hloov pauv raws li cov teeb liab modulated hloov. Nyob rau hauv Pockels electro-optic modulator, cov cab kuj-zaum lub teeb hla dhau los ntawm lub piezoelectric siv lead ua, thiab thaum lub modulated voltage yog siv, ib tug hluav taws xob teb yog generated nyob rau hauv lub piezoelectric siv lead ua, ua rau nws refractive index hloov, yog li hloov lub theem ntawm lub teeb. .Kev siv zog ua haujlwm: Qhov kev siv zog (lub teeb siv) ntawm cov khoom siv kho qhov muag hloov pauv raws li cov teeb liab modulated hloov. Kev siv kev siv zog feem ntau yog ua tiav siv Mach-Zehnder siv lub zog hloov kho, uas yog sib npaug hauv txoj cai rau Mach-Zehnder interferometer. Tom qab ob kab teeb tau hloov kho los ntawm theem hloov caj npab nrog qhov sib txawv, lawv tau cuam tshuam thaum kawg kom tau txais qhov siv zog modulated optical teeb liab.
4. Daim ntawv thov thaj chaw Electro-optical modulators muaj ntau yam kev siv hauv ntau qhov chaw, suav nrog tab sis tsis txwv rau: kev sib txuas lus kho qhov muag: Hauv kev sib txuas lus kho qhov muag kub ceev, electro-optical modulators yog siv los hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag. kom ua tiav cov ntaub ntawv encoding thiab kis tau tus mob. Los ntawm kev hloov kho qhov siv los yog theem ntawm cov teeb liab kho qhov muag, lub zog ntawm lub teeb hloov, kev tswj tus nqi tswj thiab cov teeb liab hloov pauv tuaj yeem ua tiav. Spectroscopy: Electro-optical modulators tuaj yeem siv los ua cov khoom ntawm optical spectrum analyzers rau spectral tsom xam thiab ntsuas. Kev ntsuas kev ntsuas: electro-optical modulators kuj ua lub luag haujlwm tseem ceeb hauv radar systems, kev kuaj mob thiab lwm yam haujlwm. Piv txwv li, nyob rau hauv radar systems, nws yuav siv tau rau lub teeb liab modulation thiab demodulation; Hauv kev kuaj mob, nws tuaj yeem siv rau kev kho qhov muag thiab kho qhov muag. Cov khoom siv hluav taws xob tshiab: electro-optical modulators kuj tuaj yeem siv los tsim cov khoom siv hluav taws xob tshiab, xws li cov keyboards electro-optical, optical isolators, thiab lwm yam.
5. Qhov zoo thiab qhov tsis zoo Electro-optic modulator muaj ntau yam zoo, xws li kev ntseeg siab, kev siv hluav taws xob tsawg, kev teeb tsa yooj yim, me me thiab lwm yam. Nyob rau tib lub sijhawm, nws kuj muaj cov yam ntxwv hluav taws xob zoo thiab muaj peev xwm tiv thaiv kev cuam tshuam, uas tuaj yeem siv rau kev sib kis tau zoo thiab ntau yam kev xav tau ntawm cov teeb liab. Txawm li cas los xij, lub electro-optic modulator kuj muaj qee qhov tsis txaus, xws li teeb liab kis tau tus mob qeeb, yooj yim rau kev cuam tshuam los ntawm cov hluav taws xob sab nraud. Yog li ntawd, thaum siv electro-optic modulator, nws yog ib qho tsim nyog los xaiv cov khoom tsim nyog raws li daim ntawv thov tiag tiag kom ua tiav cov txiaj ntsig zoo thiab kev ua haujlwm. Nyob rau hauv cov ntsiab lus, lub electro-optic modulator yog ib qho tseem ceeb electro-optic converter, uas muaj ib tug dav daim ntawv thov kev cia siab nyob rau hauv ntau yam xws li optical kev sib txuas lus, spectroscopy thiab kev ntsuas.
Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev xav tau ntau ntxiv rau cov khoom siv kho qhov muag pom kev zoo, electro-optical modulators yuav tsim thiab siv ntau dua.
