Waa maxay modulator-ka indhaha?

Modulator indhahaInta badan waxaa loo isticmaalaa in lagu maamulo sifooyinka iftiinka iftiinka, sida laydhka laysarka. Qalabku wuxuu maamuli karaa sifooyinka iftiinka, sida awoodda indhaha ama wajiga. Modulator iyadoo loo eegayo dabeecadda dhogorta la beddelay ayaa loo yaqaanmodulator xoojinta, modulator wejiga, modulator polarization, modulator optical spatial, iwm. Noocyada kala duwan ee modulators ayaa loo isticmaali karaa codsiyo kala duwan, sida isgaarsiinta fiber optic, qalabka bandhiga, Q-switched ama qaabka quful lasers, iyo cabbirka indhaha.

Nooca modulator-ka indhaha

Waxaa jira dhowr nooc oo kala duwan oo modulators ah:

1. Modulator Acousto-optic waa modulator ku salaysan saamaynta acousto-optic. Waxaa loo isticmaalaa in lagu beddelo ama si joogto ah loo hagaajiyo baaxadda laydhka laysarka, beddelo inta jeer ee iftiinka, ama beddelo jihada booska.

2. Themodulator-ka-elektroonigawaxay isticmaashaa saamaynta korantada-optic ee sanduuqa xumbada Kerrs. Waxay wax ka beddeli karaan gobolka polarization, wejiga, ama awoodda laydhka, ama waxaa loo isticmaali karaa soo saarista garaaca wadnaha sida lagu sheegay qaybta cod-weyneyaasha garaaca wadnaha ee ultrashort.

3. Modulator nuugista korantada waa modulator xoog leh oo loo isticmaalo gudbiyaha xogta ee isgaarsiinta fiber optic.

(4) Modulators faragelinta, sida modulators Mach-Zehnder, waxaa badanaa loo isticmaalaa wareegyada isku dhafan ee photonic ee gudbinta xogta indhaha.

5. Modulator-ka Fiber optic waxay ku salaysnaan karaan mabaadi'o kala duwan. Waxay noqon kartaa qalab fiber optic ah oo run ah, ama waxay noqon kartaa qayb ka mid ah jirka oo ay ku jiraan pigtails fiber.

6. Modulator crystal dareere ah ayaa ku haboon codsiga qalabka bandhiga indhaha ama qaabeeyaha garaaca wadnaha. Waxa kale oo loo isticmaali karaa sidii moduliyeyaasha iftiinka iftiinka, taas oo macnaheedu yahay in gudbintu ay ku kala duwan tahay meel bannaan, taas oo loo isticmaali karo qalabka bandhiga.

7. Saxanka wax-ka-beddelka ahi waxa uu si xilliyo ah u beddeli karaa awoodda laydhka, kaas oo loo isticmaalo cabbirro indho-indhayneed oo gaar ah (sida isticmaalka cod-weyneyayaasha qufulka).

8. Modulators Micromechanical (nidaamyada makaanikada, MEMS) sida qalabyada iftiinka silikoon ku salaysan iyo muraayadaha laba-geesoodka ah ayaa si gaar ah muhiim ugu ah bandhigyada saadaasha.

9. Modulators indhaha badan, sida modulators electro-optical, waxay isticmaali karaan aag dhudhun weyn waxaana sidoo kale lagu dabaqi karaa xaaladaha awooda sare leh. Modulators Fiber-ku-xidhan, badanaa modulators waveguide oo leh pigtails fiber, way fududahay in lagu dhex daro nidaamyada fiber optic.

Codsiga Modulator Optical

Modulator-ka indhaha ayaa leh codsiyo kala duwan oo dhinacyo badan leh. Kuwa soo socda waa meelaha ugu muhiimsan ee arjiyada modulators indhaha iyo codsiyadooda gaarka ah:

1. Isgaarsiinta indhaha: Nidaamyada isgaarsiinta indhaha, modulators indhaha ayaa loo isticmaalaa in lagu beddelo baaxadda, inta jeer iyo wejiga calaamadaha indhaha si loo gudbiyo macluumaadka. Waxaa caadi ahaan loo adeegsadaa tillaabooyinka muhiimka ah sida beddelka koronto-dhaliyaha, qaab-dhismeedka ishaarka indhaha iyo hoos-u-dhigga. Modulators Electro-optic waxay si gaar ah muhiim ugu yihiin hababka isgaarsiinta indhaha ee xawaaraha sare leh, kuwaas oo loo isticmaalo in lagu beddelo calaamadaha elektarooniga ah calaamadaha indhaha iyo xaqiijinta xogta xogta iyo gudbinta. Iyada oo la beddelayo xoojinta ama wejiga isha ishaarka, shaqooyinka beddelka iftiinka, xakamaynta heerka beddelka iyo habaynta calaamaduhu waa la xaqiijin karaa

2. Dareenka indhaha: Modulator-ka indhaha waxa uu ogaan karaa cabbirka iyo la socodka deegaanka isaga oo wax ka beddelaya astaamaha isha isha. Tusaale ahaan, iyadoo la beddelayo wejiga ama baaxadda iftiinka, gyroscopes fiber optic, dareemayaasha cadaadiska fiber optic, iwm.

3. Kaydinta indhaha iyo habaynta: Modulators indhaha waxaa loo isticmaalaa kaydinta indhaha iyo codsiyada processing indhaha. Xusuusta indhaha, modulators indhaha waxaa loo isticmaali karaa in lagu qoro oo lagu akhriyo macluumaadka gudaha iyo ka baxsan warbaahinta indhaha. Habaynta indhaha, modulator-ka indhaha waxa loo isticmaali karaa samaynta, shaandhaynta, habaynta iyo habaynta calaamadaha indhaha

4. Sawirka indhaha: modulators indhaha ayaa loo isticmaali karaa in lagu beddelo wejiga iyo baaxadda iftiinka iftiinka, taas oo beddeleysa sifooyinka sawirka sawirka indhaha. Tusaale ahaan, modulator field light waxa uu hirgelin karaa habaynta weji laba-cabbir ah si uu u beddelo dhererka fogaanta iyo diiradda saaraya qoto dheer ee laydhka

5. Xakamaynta dhawaqa indhaha: Modulator-ka indhaha waxa uu xakamayn karaa xoogga iyo inta jeer ee iftiinka, si uu u yareeyo ama u xakameeyo dhawaaqa indhaha ee nidaamka indhaha. Waxaa loo isticmaali karaa in amplifiers indhaha, lasers iyo hababka gudbinta fiber optic si loo hagaajiyo saamiga signal-to-sanqa iyo waxqabadka nidaamka ‌

6. Codsiyada kale: modulators electro-optical ayaa sidoo kale loo isticmaalaa falanqaynta spectral, hababka radar, ogaanshaha caafimaadka iyo qaybaha kale. spectroscopy-ga, modulator-ka korantada indhaha ayaa loo isticmaali karaa qayb ka mid ah falanqeeye spectrum spectrum falanqaynta iyo cabbiraadda. Nidaamka radar, modulator-ka elektiroonigga ah waxaa loo isticmaalaa habaynta calaamadaha iyo hoos u dhigista. Cilad-baadhista caafimaadka, modulators korantada-optic-ga waxa loo isticmaalaa sawir-qaadista iyo daawaynta.
