Horumarinta iyo xaaladda suuqa ee laysarka la hagaajin karo (Qaybta labaad)

Mabda'a shaqada eelaysar la hagaajin karo

Waxaa jira qiyaastii saddex mabda' oo lagu gaarayo hagaajinta hirarka laysarka.laysarka la hagaajin karoIsticmaal walxaha shaqeeya ee leh khadadka iftiinka badan. Resonators-ka sameeya laysarka waxay leeyihiin khasaaro aad u hooseeya oo keliya marka loo eego masaafada dheer ee aadka u cidhiidhiga ah. Sidaa darteed, tan koowaad waa in la beddelo hirarka laysarka iyadoo la beddelayo hirarka u dhigma gobolka khasaaraha hoose ee resonator-ka iyadoo la adeegsanayo walxo qaar (sida shabagga). Tan labaad waa in la beddelo heerka tamarta ee kala-guurka laysarka iyadoo la beddelayo qaar ka mid ah xuduudaha dibadda (sida goobta birlabta, heerkulka, iwm.). Tan saddexaad waa isticmaalka saamaynta aan tooska ahayn si loo gaaro isbeddelka hirarka iyo hagaajinta (fiiri indhaha aan tooska ahayn, kala firdhinta Raman ee la kiciyay, labanlaabka soo noqnoqoshada indhaha, oscillation-ka parametric-ga indhaha). Laser-yada caadiga ah ee ka tirsan qaabka hagaajinta koowaad waa laser-yada rinjiga, laser-yada chrysoberyl, laser-yada xarunta midabka, laser-yada gaaska cadaadiska sare leh ee la hagaajin karo iyo laser-yada excimer ee la hagaajin karo.

Laser-ka la hagaajin karo marka laga eego aragtida tignoolajiyada hirgelinta waxaa inta badan loo qaybiyaa: tignoolajiyada xakamaynta hadda jirta, tignoolajiyada xakamaynta heerkulka iyo tignoolajiyada xakamaynta farsamada.
Waxaa ka mid ah, tiknoolajiyada xakamaynta elektaroonigga ah waa in la gaaro hagaajinta hirarka iyadoo la beddelayo qulqulka duritaanka, iyadoo la adeegsanayo xawaaraha hagaajinta heerka NS, baaxadda hagaajinta ballaaran, laakiin awoodda wax soo saarka oo yar, oo ku salaysan tiknoolajiyada xakamaynta elektaroonigga ah inta badan SG-DBR (shabagga muunadda DBR) iyo laser GCSR (shabagga jiheynta ee isku-xidhka jihada ee dib-u-soo-saarka). Tiknoolajiyadda xakamaynta heerkulka waxay beddeshaa hirarka wax soo saarka ee leysarka iyadoo beddelaysa tusmada refractive ee gobolka firfircoon ee leysarka. Tiknoolajiyadda waa mid fudud, laakiin gaabis ah, waxaana lagu hagaajin karaa ballac cidhiidhi ah oo ah dhowr nm. Kuwa ugu muhiimsan ee ku salaysan tignoolajiyada xakamaynta heerkulka waaLaser-ka DFB(ra'yi celin la qaybiyey) iyo DBR laser (Distributed Bragg milicsiga). Xakamaynta farsamada waxay inta badan ku salaysan tahay tiknoolajiyada MEMS (micro-electro-mechanical system) si loo dhammaystiro xulashada hirarka, oo leh ballaca ballaaran ee la hagaajin karo, awood wax soo saar sare leh. Qaab-dhismeedka ugu muhiimsan ee ku salaysan tiknoolajiyada xakamaynta farsamada waa DFB (ra'yi celin la qaybiyey), ECL (laser-ka godka dibadda) iyo VCSEL (laser-ka dusha sare ee daloolka toosan). Kuwa soo socda waxaa lagu sharraxay dhinacyadan mabda'a leysarka la hagaajin karo.

Codsiga isgaarsiinta indhaha

Laser-ka la hagaajin karo waa aalad muhiim u ah optoelectronic-ka jiilka cusub ee nidaamka isku-dhafka dhererka cufan ee kala-qaybinta hirarka iyo is-weydaarsiga photon ee shabakadda indhaha oo dhan. Adeegsigeedu wuxuu si weyn u kordhiyaa awoodda, dabacsanaanta iyo ballaarinta nidaamka gudbinta fiber-ka indhaha, wuxuuna hirgeliyay hagaajin joogto ah ama mid isku-dhafan oo ku jirta mowjado ballaaran.
Shirkadaha iyo hay'adaha cilmi-baarista ee adduunka oo dhan ayaa si firfircoon u dhiirrigelinaya cilmi-baarista iyo horumarinta laysarka la hagaajin karo, horumar cusubna si joogto ah ayaa looga sameynayaa arrintan. Waxqabadka laysarka la hagaajin karo si joogto ah ayaa loo hagaajiyaa qiimahana si joogto ah ayaa loo dhimaa. Waqtigan xaadirka ah, laysarka la hagaajin karo waxaa inta badan loo qaybiyaa laba qaybood: laysarka la hagaajin karo ee semiconductor iyo laysarka fiber-ka la hagaajin karo.
Laser-ka Semiconductor-ka ahwaa il iftiin oo muhiim ah oo ku jira nidaamka isgaarsiinta indhaha, kaas oo leh astaamo cabbir yar, miisaan fudud, hufnaan beddelka sare, keydinta awoodda, iwm., waana mid si fudud loo gaari karo is-dhexgalka optoelectronic-ka ee hal-chip ah oo leh aaladaha kale. Waxaa loo qaybin karaa laser jawaab celin ah oo la hagaajin karo oo la qaybin karo, laser muraayad Bragg ah oo la qaybiyey, nidaamka micromotor-ka oo ah dalool toosan oo soo saaraya laysarka dusha sare ee godka iyo laysarka semiconductor-ka ee dibadda.
Horumarinta laysarka fiber-ka ee la hagaajin karo oo ah dhexdhexaad gaabin iyo horumarinta diode-ka laser-ka semiconductor-ka oo ah isha bamka ayaa si weyn u horumariyay horumarinta laysarka fiber-ka. laysarka la hagaajin karo wuxuu ku salaysan yahay baaxadda faa'iidada 80nm ee faybarka la duray, qaybta shaandhadana waxaa lagu daraa wareegga si loo xakameeyo hirarka lasing-ka loona xaqiijiyo hagaajinta hirarka.
Horumarinta laysarka semiconductor-ka ee la hagaajin karo aad ayuu uga firfircoon yahay adduunka, horumarkuna sidoo kale aad buu u degdeg badan yahay. Maadaama laysarka la hagaajin karo ay si tartiib tartiib ah ugu soo dhawaadaan laysarka mowjadaha go'an marka loo eego kharashka iyo waxqabadka, waxaa si lama huraan ah loogu isticmaali doonaa nidaamyada isgaarsiinta waxayna door muhiim ah ka ciyaari doonaan shabakadaha indhaha ee mustaqbalka.

Rajada horumarinta
Waxaa jira noocyo badan oo ah laysarka la hagaajin karo, kuwaas oo guud ahaan lagu sameeyo iyadoo la sii wado farsamooyinka hagaajinta hirarka iyadoo lagu saleynayo laysarka hal-wareegga ah ee kala duwan, qaar ka mid ahna waxaa suuqa loo keenay si caalami ah. Marka laga soo tago horumarinta laysarka la hagaajin karo ee indhaha oo joogto ah, laysarka la hagaajin karo oo leh hawlo kale oo isku dhafan ayaa sidoo kale la soo sheegay, sida laysarka la hagaajin karo oo lagu dhex daray hal jajab oo VCSEL ah iyo modulator nuugista korontada, iyo laysarka oo lagu dhex daray milicsiga Bragg ee muunadda iyo amplifier-ka indhaha ee semiconductor iyo modulator nuugista korontada.
Maadaama leysarka la hagaajin karo ee hirarka dheer si weyn loo isticmaalo, leysarka la hagaajin karo ee qaabab kala duwan ayaa loo isticmaali karaa nidaamyo kala duwan, mid walbana wuxuu leeyahay faa'iidooyin iyo khasaarooyin. Leysarka semiconductor-ka ee godka dibadda waxaa loo isticmaali karaa sidii il iftiin oo la hagaajin karo oo ballaaran oo ku jira qalabka tijaabada saxda ah sababtoo ah awooddiisa sare ee wax soo saarka iyo hirarka la hagaajin karo ee joogtada ah. Marka laga eego aragtida isdhexgalka photon iyo la kulanka shabakadda indhaha oo dhan ee mustaqbalka, shabagga muunadda DBR, shabagga DBR ee la hagaajin karo ee sarreeya iyo leysarka la hagaajin karo ee lagu daray modulators iyo amplifiers-ka ayaa laga yaabaa inay rajo ka qabaan ilo iftiin oo la hagaajin karo oo loogu talagalay Z.
Laser-ka la hagaajin karo ee fiber-ka oo leh god dibadeed ayaa sidoo kale ah nooc rajo leh oo ah isha iftiinka, kaas oo leh qaab-dhismeed fudud, ballaca xariiqda cidhiidhiga ah iyo isku-xidhka fiber-ka fudud. Haddii modulator-ka EA lagu dhex dari karo godka, waxaa sidoo kale loo isticmaali karaa sidii isha soliton-ka indhaha ee xawaaraha sare leh ee la hagaajin karo. Intaa waxaa dheer, laser-ka fiber-ka ee la hagaajin karo ee ku salaysan laser-ka fiber-ka ayaa sameeyay horumar la taaban karo sannadihii ugu dambeeyay. Waxaa la filan karaa in waxqabadka laser-ka la hagaajin karo ee ilaha iftiinka isgaarsiinta indhaha la sii wanaajin doono, saamiga suuquna uu si tartiib tartiib ah u kordhi doono, iyadoo la filayo codsi aad u dhalaalaya.
