Tshawb nrhiav cov kev tsis paub txog lub teeb: Cov ntawv thov tshiab rauElectro-Optic Modulator Linbo3 theem modulators

Lixbo3 modulatorTheem Modulator yog lub ntsiab tseem ceeb uas tuaj yeem tswj cov theem hloov pauv ntawm lub teeb nthwv dej, thiab nws plays lub luag haujlwm tseem ceeb hauv kev sib txuas lus thiab kev xav tau. Tsis ntev los no, ib hom tshiab ntawmTheem Modulatortau nyiam cov kev saib xyuas ntawm cov kws tshawb nrhiav thiab engineers, uas ua haujlwm ntawm peb wavulength ntawm 7,64nm, nrog kev sib cais bandwidths txog li 300MHz, 20GHz thiab 40GHz.

Qhov tseem ceeb tshaj plaws ntawm theem no modulator yog cov kev ntsuas kub thiab tsawg txoj kev poob. Cov ntxig los poob hais txog qhov txo qis hauv kev siv lossis lub zog ntawm lub teeb liab kho qhov muag tom qab dhau los ntawm tus modulator. Cov ntxig kev poob ntawm cov theem no muaj txiaj ntsig tsawg, uas ua kom muaj kev ncaj ncees ntawm lub teeb liab, yog li ntawd lub teeb liab tuaj yeem tswj tau lub zog siab tom qab kev hloov kho.

Ib qho ntxiv, tus lej teeb meem muaj cov yam ntxwv ntawm cov neeg yoj ib nrab yoj. Ib nrab-yoj volage yog qhov hluav taws xob uas xav tau los thov rau tus modulator kom hloov theem ntawm lub teeb los ntawm 180 degrees. Qhov tsawg ib nrab-yoj voltage txhais tau tias tsuas yog qis dua voltage yog xav tau kom ua tiav qhov kev hloov pauv tseem ceeb hauv lub zog ntawm cov cuab yeej.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, no theem tshiab modulator tuaj yeem yog siv dav nyob rau hauv cov kev sib txuas lus zoo, theem ncua fiber ntau, theem qeeb (shifter), thiab quantum sib txuas lus. Nyob rau hauv cov ntsuas hluav taws xob kho qhov muag, theem modulator tuaj yeem txhim kho qhov rhiab thiab daws teeb meem ntawm lub sensor. Hauv kev sib txuas lus siv kho qhov muag fiber ntau, nws tuaj yeem txhim kho kev sib txuas lus ceev thiab cov ntaub ntawv sib kis tau zoo. Nyob rau hauv Theem Kev ncua (shifter), nws tuaj yeem tswj hwm kev coj ua ntawm lub teeb tshaj tawm; Hauv kev sib txuas lus quantum, nws tuaj yeem siv los tswj thiab tswj xyuas cov quant).

Zuag qhia tag nrho, cov qeb tshiab muab peb zoo dua thiab muaj kev tswj kho qhov muag tau txhais tau tias, uas yuav hloov pauv kev hloov pauv hauv ntau thaj teb. Peb cia siab tias cov thev naus laus zis no yuav tau tsim ntxiv thiab ua kom zoo tshaj plaws nyob rau yav tom ntej, pom ntau dua qhov kev tsis pom zoo ntxiv rau peb.
