Tshawb nrhiav qhov paub tsis meej ntawm lub teeb: Cov ntawv thov tshiab rauElectro-Optic Modulator LiNbO3 theem modulators
LiNbO3 modulatorPhase modulator yog lub hauv paus tseem ceeb uas tuaj yeem tswj cov theem hloov ntawm lub teeb nthwv dej, thiab nws ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus kho qhov muag niaj hnub thiab kev paub. Tsis ntev los no, ib hom tshiab ntawmtheem modulatortau nyiam cov neeg tshawb nrhiav thiab engineers, uas ua haujlwm ntawm peb lub wavelengths ntawm 780nm, 850nm thiab 1064nm, nrog kev hloov pauv bandwidths txog 300MHz, 10GHz, 20GHz thiab 40GHz.
Qhov tseem ceeb tshaj plaws ntawm lub sijhawm modulator no yog qhov hloov pauv siab bandwidth thiab tsis muaj qhov nkag tsis zoo. Insertion poob yog hais txog qhov txo qis hauv kev siv lossis lub zog ntawm cov teeb liab kho qhov muag tom qab dhau los ntawm lub modulator. Qhov poob ntawm qhov kev hloov pauv ntawm theem no yog qhov tsawg kawg nkaus, uas ua kom muaj kev ncaj ncees ntawm cov teeb liab, kom lub teeb liab tuaj yeem tswj tau lub zog siab tom qab kev hloov kho.
Tsis tas li ntawd, cov theem modulator muaj cov yam ntxwv ntawm qhov qis ib nrab-yoj voltage. Ib nrab-yoj voltage yog qhov voltage uas yuav tsum tau siv rau lub modulator thiaj li yuav hloov lub theem ntawm lub teeb los ntawm 180 degrees. Qhov qis ib nrab-yoj voltage txhais tau hais tias tsuas yog ib qho hluav taws xob qis yog xav tau kom ua tiav qhov kev hloov pauv tseem ceeb hauv lub sijhawm kho qhov muag, uas txo qis kev siv lub zog ntawm lub cuab yeej.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, no theem tshiab modulator yuav dav siv nyob rau hauv optical fiber sensing, kho qhov muag fiber kev sib txuas lus, theem ncua (shifter), thiab quantum kev sib txuas lus. Hauv optical fiber sensing, theem modulator tuaj yeem txhim kho qhov rhiab heev thiab kev daws teeb meem ntawm lub sensor. Hauv kev sib txuas lus fiber ntau optical, nws tuaj yeem txhim kho kev sib txuas lus ceev thiab cov ntaub ntawv xa mus tau zoo. Nyob rau hauv lub sij hawm ncua (shifter), nws muaj peev xwm precisely tswj cov kev taw qhia ntawm lub teeb propagation; Hauv kev sib txuas lus quantum, nws tuaj yeem siv los tswj thiab tswj cov xeev quantum.
Zuag qhia tag nrho, tus tshiab theem modulator muab rau peb nrog ntau npaum thiab raug kho qhov muag txhais tau tias, uas yuav coj revolutionary kev hloov nyob rau hauv ntau yam teb. Peb cia siab tias cov thev naus laus zis no yuav raug tsim kho ntxiv thiab ua tiav rau yav tom ntej, nthuav tawm ntau qhov kev paub tsis meej rau peb.
