Muaj kev nkag siab zoo ntawm electro-optic modulators
Lub electro-optic modulator (Yam tseem ceeb) yog cov khoom siv hluav taws xob electro-siv hluav taws xob cov cim tswj hwm cov cim hluav taws xob, feem ntau yog siv rau txheej txheem hloov dua tshiab
Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau electro-optic modulator:
1. Tus txheej txheem yooj yim ntawm lubElectro-Optic Modulatoryog ua raws cov khoom siv hluav taws xob hluav taws xob, uas yog, qhov ntsuas hluav taws xob ua haujlwm tshiab ntawm qee cov ntaub ntawv yuav hloov raws li kev nqis tes ua ntawm kev ua lag luam hluav taws xob. Raws li lub teeb vuag hla dhau los ntawm cov muaju no, cov yam ntxwv tshaj tawm cov yam ntxwv hloov nrog hluav taws xob teb. Siv lub ntsiab cai no, lub theem, amplitude lossis polarization xeev ntawm lubntawm qhov muagCov teeb liab tuaj yeem tswj los ntawm kev hloov pauv hluav taws xob.
2. Cov qauv thiab sib xyaw Electro-optical modulators feem ntau muaj ntawm kev kho mob kho qhov muag, cov ntxaij lim dej thiab cov tshuab ntsuas hluav taws xob. Ib qho ntxiv, nws suav nrog cov tsav tsheb tseem ceeb xws li cov tsav tsheb ceev, kho qhov muag kho qhov muag thiab cov zaub mov piezoelectric. Tus qauv ntawm cov qauv hluav taws xob hluav taws xob tuaj yeem sib txawv raws li nws cov kev txiav txim siab hom: Electro-optic inverter module thiab photoinectric kev hloov kho.
3. Kev Hloov Hom Electro-Optic Modulator muaj ob hom kev sib cav loj:THEEM kev hloov khothiab siv kev hloov pauv. THEEM MODULATION: Cov theem ntawm cov cab kuj hloov raws li cov teeb liab hloov kho. Hauv Pockels Electro-Distric-zaus lub teeb dhau los ntawm cov crystal crystal, thiab thaum muaj hluav taws xob modulation los hloov, yog li hloov theem ntawm lub teeb Cov.Kev siv cov kev hloov kho: Kev siv (lub teeb siv) ntawm cov cab kuj kho qhov muag hloov pauv raws li cov teeb liab hloov kho. Kev siv cov kev hloov kho yog feem ntau siv lub ntsej muag mach-zeatnder siv modulator, uas yog sib npaug hauv lub ntsej muag rau kev ua kom huv. Tom qab ob kab teeb tau modulated los ntawm theem shifting txhais caj npab nrog cov sib txawv sib txawv, lawv thaum kawg cuam tshuam nrog kom tau txais kev sib zog hloov kho qhov muag.
4. Daim ntawv thov Cheeb Tsam Electro-optical modulators muaj ntau cov kev siv hauv cov ntawv sib txuas lus zoo, suav nrog kev sib txuas lus kho qhov muag tau siv los hloov cov cim hluav taws xob rau hauv cov cim hluav taws xob kom ua tiav cov ntaub ntawv encoding thiab kis. Los ntawm kev siv cov teeb meem lossis theem ntawm lub teeb liab kho qhov muag, kev siv lub teeb hloov, kev tswj hwm tes taws thiab teeb liab kev tswj hwm tau. Spectroscopy: Electro-optical modulators tuaj yeem siv los ua cov khoom sib xyaw ntawm cov tshuaj ntsuam xyuas thiab ntsuas. Kev ntsuas kev ntsuas: kev kho mob Electro-optical modulators kuj tseem ceeb hauv cov tshuab radar, kuaj mob thiab lwm thaj teb. Piv txwv li, nyob rau hauv lub tshuab ci radar, nws tuaj yeem siv rau teeb liab kev hloov kho thiab demodulation; Hauv kev kuaj mob, nws tuaj yeem siv rau kev ntsuas kho qhov muag thiab kho. Cov cuab yeej siv yees duab tshiab: Electro-optical modulators kuj tseem siv tau los tsim cov khoom siv tiag tiag, xws li hloov kho hluav taws xob, kho kom zoo nkauj, thiab lwm yam.
5. Nyob rau tib lub sijhawm, nws kuj muaj cov yam ntxwv hluav taws xob zoo thiab kev tawm tsam cuam tshuam, uas tuaj yeem siv rau cov kev xav tau broadand bar thiab ntau yam teeb liab kev xav tau. Txawm li cas los xij, lub electro-optic modulator tseem muaj qee qhov tsis txaus ntseeg, xws li kis tus kis tau qeeb, yooj yim rau kev cuam tshuam nrog hluav taws xob hluav taws xob sab nraud hluav taws xob hluav taws xob. Yog li ntawd, thaum siv Electro-Optic Modulator, nws yog ib qho tsim nyog los xaiv cov khoom zoo raws li daim ntawv thov tau txais txiaj ntsig zoo thiab ua tau zoo. Hauv cov ntsiab lus, lub electro-optic modulator yog qhov tseem ceeb electro-optic converter, uas muaj kev cia siab rau kev sib txuas lus zoo xws li kev sib txuas lus thiab ntsuas kev ntsuas thiab ntsuas.
Nrog kev kawm txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev ua tau zoo dua rau cov khoom siv kho qhov muag zoo tshaj plaws, cov khoom siv kho mob electro-ELECTROCH
