Electro-optic modulatoryog lub cuab yeej tseem ceeb los hloov kho cov teeb liab laser tas mus li siv cov ntaub ntawv, xov tooj cua zaus thiab cov teeb liab moos. Cov qauv sib txawv ntawm modulator muaj cov haujlwm sib txawv. Los ntawm lub modulator kho qhov muag, tsis yog tsuas yog tuaj yeem hloov pauv qhov muaj zog ntawm lub teeb nthwv dej xwb, tab sis kuj tseem tuaj yeem hloov kho theem thiab lub xeev polarization ntawm lub teeb nthwv dej. Cov modulators electro-optic feem ntau siv yog Mach-Zehndercov khoom siv hloov kho qhov muaj zogthiabcov modulators theem.
LubLiNbO3 lub zog modulatoryog siv dav hauv kev sib txuas lus optical ceev ceev, laser sensing thiab ROF systems vim muaj kev ua tau zoo electro-optic. Cov koob R-AM raws li MZ push-pull qauv thiab X-cut tsim, muaj cov yam ntxwv lub cev thiab tshuaj ruaj khov, uas tuaj yeem siv rau hauv kev sim hauv chaw kuaj mob thiab cov tshuab kev lag luam.

Cov kev cai rau qhov sib piv siab ntawm kev ploj tuag
1. Tus modulator system yuav tsum muaj qhov piv txwv siab tshaj plaws ntawm kev ploj mus. Tus yam ntxwv ntawm tus modulator system txiav txim siab qhov piv txwv siab tshaj plaws ntawm kev ploj mus tuaj yeem ua tiav.
2. Yuav tsum tau saib xyuas qhov polarization ntawm lub teeb modulator. Cov modulators rhiab heev rau polarization. Polarization kom raug tuaj yeem txhim kho qhov piv txwv ploj mus ntau dua 10dB. Hauv kev sim hauv chav kuaj, feem ntau xav tau tus tswj polarization.
3. Cov tswj hwm kev tsis ncaj ncees kom zoo. Hauv peb qhov kev sim DC extinction ratio, 50.4dB extinction ratio tau ua tiav. Thaum daim ntawv qhia txog cov khoom siv modulator tsuas yog teev 40dB. Qhov laj thawj ntawm qhov kev txhim kho no yog tias qee cov modulators txav mus sai heev. Rofea R-BC-ANY bias controllers hloov kho qhov bias voltage txhua 1 vib nas this kom ntseeg tau tias muaj kev teb sai.
ROF tau tsom mus rau electro-optic integrated circuits thiab cov khoom rau ib xyoo caum. Peb tsim cov high-performance integrated-optical modulators thiab muab cov kev daws teeb meem tshiab thiab cov kev pabcuam rau cov kws tshawb fawb thiab cov engineers kev lag luam. Cov modulators ntawm Rofea nrog qis drive voltage thiab qis insertion poob tau siv feem ntau hauv quantum key distribution, radio-over-fiber systems, laser sensing systems, thiab next-generation optical telecommunication.
Peb kuj muab ntau yam modulators tshwj xeeb rau kev hloov kho, xws li 1 * 4 array phase modulators, ultra-low Vpi, thiab ultra-high extinction ratio modulators, feem ntau siv hauv cov tsev kawm qib siab thiab cov koom haum. Tsis tas li ntawd, peb kuj tsim RF amplifier (modulator driver) thiab BIAS controller, photonics detector thiab lwm yam.
Yav tom ntej, peb yuav txuas ntxiv txhim kho cov khoom lag luam uas twb muaj lawm, los tsim kom muaj pab pawg kws tshaj lij, txuas ntxiv muab cov khoom lag luam zoo, txhim khu kev qha, thiab cov kev pabcuam tshaj lij rau cov neeg siv.
