Electro-Optic ModulatorPuas yog cov cuab yeej tseem ceeb rau kev hloov kho cov teeb txuas ntxiv laser siv cov ntaub ntawv, xov tooj cua tau thiab cov cim teev. Cov qauv sib txawv ntawm cov qauv muaj cov haujlwm sib txawv. Los ntawm cov hloov kho kho qhov muag, tsis yog tsuas yog siv tau ntawm lub teeb yoj hloov, tab sis kuj tseem muaj theem thiab polarization xeev ntawm lub teeb dej yuav hloov kho. Feem ntau siv electro-optic modulators yog mach-zeathnderZog ModulatorsthiabTheem Modulators.
TusLixbo3 kev siv cov qauvyog dav siv nyob rau hauv kev kub ceev kho qhov muag kev sib txuas lus, laser sensing thiab rofl tshuab vim tias zoo electro-optic kev ua haujlwm. Lub R-AM raws li MZ laub-rub qauv thiab x-txiav tsim thiab x-txiav tsim, muaj cov yam ntxwv ruaj khov, uas tuaj yeem thov cov kev sim thiab kev siv hluav taws xob.

Yuav tsum muaj rau cov piv txwv tseem ceeb
1. Cov txheej txheem Modulator yuav tsum muaj cov piv txwv txiav txim siab. Cov yam ntxwv ntawm cov kab ke kev txiav txim siab qhov kev sib piv siab tshaj plaws tau ua tiav.
2. Polarization ntawm Modulator tawm tswv yim lub teeb yuav tsum tau saib xyuas. Modulators yog nkag siab txog kev sib tw. Raws li kev ua kom raug cai tau zoo tuaj yeem txhim kho kev tshem tawm tas li 10dB. Hauv kev sim ua haujlwm lab, feem ntau yog tus kws sau tshuaj polarization yog xav tau.
3. Tsim nyog cov neeg muaj tswv yim tsis zoo. Hauv peb DC excinction sib piv, 50.4db extinction ratio tau tiav lawm. Thaum lub datasheet ntawm modulator siv xwb tsuas yog teev 40dB. Qhov laj thawj ntawm txoj kev txhim kho no yog tias qee cov modulators drift heev. Rofile R-BC-TXHUA YAM KEV TXHAJ TSHUAJ HLOOV LUB BIAS TXHUA Voltage Txhua 1 Thib Ob Los Xyuas Kom Muaj Kev Teb Rov Qab Los.
ROF tau tsom rau electro-optic sib xyaw ua ke circuits thiab cov khoom sib xyaw rau ib xyoo caum. Peb tsim cov kev ua tau zoo ntawm cov kev ua haujlwm ntawm cov kev ua lag luam thiab muab cov kev daws teeb meem thiab cov kev tshawb fawb tshiab rau cov kws tshawb fawb thiab cov kev lag luam tshuab. Cov modulators ntawm cov refea nrog cov tsav hluav taws xob tsawg dua thiab cov khoom lag luam tseem ceeb ntau, cov xov tooj cua tseem ceeb, thiab cov khoom siv kho kom zoo dua qub.
Peb tseem muab ntau cov neeg modulators rau kev hloov kho, xws li 1 * 4 Array theem modulators, thiab ultra-siab extinction piv, feem ntau siv nyob rau hauv cov tsev kawm qib siab thiab lub tsev. Tsis tas li ntawd, peb kuj tsim RF amplifier (modulator tsav tsheb) thiab bias maub los, Phows ntes thiab lwm yam.
Nyob rau yav tom ntej, peb yuav txuas ntxiv txhim kho cov khoom lag luam khoom muaj, txuas ntxiv muab cov neeg siv kev tshaj lij, txhim khu kev qha, cov khoom lag luam siab thiab kev pabcuam.
