Cov ntawv thov tshiab rauElectro-Optic theem modulator
LiNbO3 modulatorTheem modulator yog ib qho tseem ceeb uas tuaj yeem tswj qhov kev hloov pauv ntawm lub teeb nthwv dej, thiab nws ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus niaj hnub thiab kev tshutheem modulatortau nyiam cov kws tshawb fawb thiab cov engineers, uas ua haujlwm ntawm peb lub wavelengths ntawm 780nm, 850nm thiab 1064nm, nrog rau modulation bandwidths txog li 300MHz, 10GHz, 20GHz thiab 40GHz.
Qhov tseem ceeb tshaj plaws ntawm lub modulator theem no yog qhov bandwidth siab modulation thiab qhov poob qis ntawm kev ntxig. Kev poob qis ntawm kev ntxig yog hais txog qhov txo qis ntawm qhov muaj zog lossis lub zog ntawm lub teeb liab kho qhov muag tom qab dhau los ntawm lub modulator. Qhov poob qis ntawm lub modulator theem no yog qis heev, uas ua kom muaj kev ncaj ncees ntawm lub teeb liab, yog li lub teeb liab tuaj yeem tswj tau lub zog siab tom qab modulation.
Ntxiv mus, tus modulator theem muaj tus yam ntxwv ntawm qhov hluav taws xob qis ib nrab nthwv dej. Qhov hluav taws xob ib nrab nthwv dej yog qhov hluav taws xob uas yuav tsum tau siv rau tus modulator kom hloov theem ntawm lub teeb los ntawm 180 degrees. Qhov hluav taws xob qis ib nrab nthwv dej txhais tau tias tsuas yog qhov hluav taws xob qis dua xwb thiaj li ua tiav qhov kev hloov pauv tseem ceeb hauv theem kho qhov muag, uas txo qhov kev siv hluav taws xob ntawm lub cuab yeej.
Nyob rau hauv cov teb ntawm daim ntawv thov, qhov tshiab theem modulator no tuaj yeem siv dav hauv optical fiber sensing, optical fiber kev sib txuas lus, theem qeeb (shifter), thiab kev sib txuas lus quantum. Hauv optical fiber sensing, theem modulator tuaj yeem txhim kho qhov rhiab heev thiab kev daws teeb meem ntawm lub sensor. Hauv optical fiber kev sib txuas lus, nws tuaj yeem txhim kho qhov ceev ntawm kev sib txuas lus thiab kev xa cov ntaub ntawv zoo. Hauv theem qeeb (shifter), nws tuaj yeem tswj tau qhov kev taw qhia ntawm lub teeb kis; Hauv quantum kev sib txuas lus, nws tuaj yeem siv los tswj thiab tswj cov xwm txheej quantum.
Zuag qhia tag nrho, tus modulator theem tshiab muab rau peb cov cuab yeej tswj kev pom kev zoo dua thiab raug dua, uas yuav coj kev hloov pauv tshiab hauv ntau qhov chaw. Peb cia siab tias cov thev naus laus zis no yuav raug tsim kho thiab ua kom zoo dua yav tom ntej, qhia ntau yam tsis paub meej txog kev pom kev rau peb.
