Faham buuxa oo ku saabsan modulators electro-optic
Modulator Electro-optic (EOM) waa beddelka elektiroonigga ah ee isticmaala calaamadaha korantada si loo xakameeyo calaamadaha indhaha, inta badan loo isticmaalo habka beddelka calaamadaha indhaha ee goobta tignoolajiyada isgaarsiinta.
Kuwa soo socdaa waa horudhac tafatiran oo ku saabsan modulator-ka elektiroonigga ah:
1. Mabda'a aasaasiga ah eemodulator elektaroonik ahwaxay ku salaysan tahay saamaynta electro-optic, taas oo ah, index refractive ee alaabta qaar ka mid ah ayaa isbeddeli doona hoos waxqabadka beer koronto codsatay. Sida mowjadaha iftiinka ay dhex maraan kiristaalo, sifooyinka faafinta waxay isku beddelaan goobta korantada. Isticmaalka mabda'a this, marxaladda, baaxadda ama polarization xaaladda eeindhahacalaamada waxaa lagu xakameyn karaa iyadoo la bedelayo goobta korontada ee codsatay.
2. Qaab dhismeedka iyo halabuurka Modulators Electro-optical waxay guud ahaan ka kooban yihiin waddooyinka indhaha, cod-weyneyaasha, filtarrada iyo beddelayaasha korantada. Intaa waxaa dheer, waxaa ku jira qaybaha muhiimka ah sida darawallada xawaaraha sare leh, fiilooyinka indhaha iyo kiristaalo piezoelectric. Qaab dhismeedka modulator-ka elektiroonigga ah wuu kala duwanaan karaa iyadoo loo eegayo qaabkiisa qaabaynta iyo shuruudaha codsiga, laakiin inta badan waxaa ku jira laba qaybood: moduleka inverter-ka-electro-optic iyo module modulation photoelectric.
3. Qaabka wax-ka-beddelka Modulator-ka-optic-ga wuxuu leeyahay laba hab-habboon oo waaweyn:habaynta wajigaiyo habaynta xoojinta. Habaynta Wajiga: Marxaladda side side ayaa isbedesha marka calaamada la habeeyay uu isbedelo. Modulator-ka 'Pockels electro-optic modulator', iftiinka sidaha-soo noqnoqda wuxuu dhex maraa crystal piezoelectric, iyo marka koronto la hagaajiyay lagu dabaqo, beer koronto ayaa laga soo saarayaa crystal piezoelectric, taasoo keenaysa in tusaha refractive inuu isbedelo, sidaas darteed beddelo wajiga iftiinka. .Habaynta xoojinta: Xoogagga (iftiinka iftiinka) ee sidaha indhaha ayaa isbeddelaya marka calaamadda la beddelay Hababka xoojinta waxaa badanaa lagu gaaraa iyadoo la adeegsanayo modulator-ka xoojinta Mach-Zehnder, kaas oo mabda' ahaan u dhigma interferometer-ka Mach-Zehnder. Ka dib markii labada alwaax ay qaabeeyaan cudud wareegeysa wajiga oo leh xoogaa kala duwan, ugu dambeyntii waa la farageliyaa si ay u helaan ishaarada indhaha ee la hagaajiyay.
4. Meelaha laga codsado Modulators Electro-optical Modulators waxay leeyihiin codsiyo kala duwan oo dhinacyo badan ah, oo ay ku jiraan laakiin aan ku xaddidnayn: isgaarsiinta indhaha: Nidaamyada isgaarsiineed ee xawaaraha sare leh, modulators electro-optical modulators ayaa loo isticmaalaa si loogu beddelo calaamadaha elektiroonigga ah calaamadaha indhaha. si loo gaaro codaynta iyo gudbinta xogta. Iyada oo la beddelayo xoojinta ama wejiga ishaarka indhaha, shaqooyinka beddelka iftiinka, xakamaynta heerka beddelka iyo habaynta calaamadaha ayaa la xaqiijin karaa. Spectroscopy: Modulators Electro-optical waxa loo isticmaali karaa sidii qaybo ka mid ah falanqeeyayaasha spectrum spectrum ee falanqaynta spectral iyo cabbirka. Cabbiraadda farsamada: Modulator-ka korantada indhaha ayaa sidoo kale door muhiim ah ka ciyaara nidaamyada radar, baarista caafimaadka iyo qaybaha kale. Tusaale ahaan, nidaamyada radar, waxaa loo isticmaali karaa is-beddelka calaamadaha iyo hoos u dhigista; Baaritaanka caafimaadka, waxaa loo isticmaali karaa sawir-qaadista iyo daawaynta. Aaladaha korontada ee cusub: modulators-ka korantada sidoo kale waxaa loo isticmaali karaa in lagu soo saaro aaladaha korontada ee cusub, sida furayaasha korantada, go'doominta indhaha, iwm.
5. Faa'iidooyinka iyo khasaaraha Modulator Electro-optic wuxuu leeyahay faa'iidooyin badan, sida kalsoonida sare, isticmaalka tamarta yar, rakibida fudud, cabbir yar iyo wixii la mid ah. Isla mar ahaantaana, waxay sidoo kale leedahay sifooyin koronto oo wanaagsan iyo awoodda ka hortagga faragelinta, taas oo loo isticmaali karo gudbinta ballaaran iyo baahiyo kala duwan oo ka mid ah hababka calaamadaha. Si kastaba ha ahaatee, modulator-ka korantada-optic-ga waxa kale oo uu leeyahay cilladaha qaarkood, sida daahitaanka gudbinta signalka, oo ay fududahay in ay farageliyaan mowjadaha korantada ee dibadda. Sidaa darteed, marka la isticmaalayo modulator-ka elektiroonigga ah, waxaa lagama maarmaan ah in la doorto badeecada saxda ah iyadoo loo eegayo baahida dhabta ah ee codsiga si loo gaaro saameyn wanaagsan oo isbeddel ah iyo waxqabadka. Isku soo wada duuboo, modulator-ka korantada-optic-ga ayaa ah beddele elektro-optic oo muhiim ah, kaas oo leh rajo ballaadhan oo dhinacyo badan leh sida isgaadhsiinta indhaha, spectroscopy iyo cabbir farsamo.
Horumarka joogtada ah ee sayniska iyo tignoolajiyada iyo baahida sii kordheysa ee loo qabo aaladaha indhaha ee wax qabadkoodu sarreeyo, modulators-ka elektiroonigga ah ayaa si ballaaran loo horumarin doonaa oo lagu dabaqi doonaa.
