Horumarka iyo heerka suuqa ee leysarka la hagaajin karo (Qaybta labaad)

Mabda'a shaqada eelaser la hagaajin karo

Waxaa jira qiyaas ahaan saddex mabda'a oo lagu gaaro hagaajinta hirarka dhererka laysarka.Inta badanleysarka la hagaajin karoIsticmaal walxaha shaqada leh xadhkaha dhaadheer ee ballaaran.Resonators-ka ka kooban laser-ku waxay leeyihiin khasaare aad u hooseeya oo keliya marka loo eego baaxadda hirarka dhererka cidhiidhiga ah.Sidaa darteed, tan ugu horreysa waa in la beddelo hirarka dhererka leysarka iyadoo la beddelayo hirarka u dhigma gobolka luminta hooseeya ee resonator-ka xubno ka mid ah (sida shabag).Midda labaad waa in la beddelo heerka tamarta ee kala-guurka laysarka iyadoo la beddelayo qaar ka mid ah xuduudaha dibadda (sida goobta magnetic, heerkulka, iwm.).Midda saddexaad waa adeegsiga saamaynta aan tooska ahayn si loo gaaro isbeddelka hirarka dhererka iyo hagaajinta (eeg muuqaallada aan tooska ahayn, kala firdhisanaanta Raman ee la kiciyay, labanlaabida soo noqnoqda indhaha, oscillation parametric indhaha).Laysarada caadiga ah ee ka tirsan qaabka ugu horreeya ee laxamiistaha waa laysarka dheeha, laser-ka chrysoberyl, leysarka xarunta midabka, laser gaaska cadaadiska sare leh oo la hagaajin karo iyo lasers-ka-baxsan ee la hagaajin karo.

Laysarka la dami karo marka loo eego tignoolajiyada xaqiijinta waxa inta badan loo kala qaybiyaa: tignoolajiyada hadda jirta, tignoolajiyada xakamaynta heerkulka iyo farsamada gacanta ee farsamada.
Waxaa ka mid ah, tignoolajiyada kontoroolka elektiroonigga ah waa in lagu gaaro hagaajinta hirarka dhererka iyadoo la beddelayo duritaanka hadda, iyadoo xawaaraha hagaajinta heerka NS, bandwidth ballaaran, laakiin awood wax soo saar yar, oo ku saleysan tignoolajiyada kontoroolka elektiroonigga ah inta badan SG-DBR (Sampling grating DBR) iyo GCSR leysarka (milicsiga muunad gadaal-u-qaadista)Tignoolajiyada xakamaynta heerkulku waxay beddeshaa mawjadda dhererka wax soo saarka ee leysarka iyadoo beddeleysa index refractive ee gobolka firfircoon ee laysarka.Tignoolajiyadu waa mid fudud, laakiin gaabis ah, waxaana lagu hagaajin karaa ballac cidhiidhi ah oo dhawr nm ah.Kuwa ugu muhiimsan ee ku salaysan tiknoolajiyada xakamaynta heerkulka waaDFB laser(celinta la qaybiyay) iyo DBR laser (Milicsiga Bragg Qaybsan).Xakamaynta makaanikada inta badan waxay ku saleysan tahay tignoolajiyada MEMS (nidaamka micro-electro-mechanical) si loo dhamaystiro xulashada mawjada dhererka, oo leh xajmi weyn oo la hagaajin karo, awood sare oo wax soo saar leh.Qaab dhismeedka ugu muhiimsan ee ku saleysan tignoolajiyada kontoroolka farsamada waa DFB ( jawaab celin qaybsan), ECL (laysarka daloolka dibadda) iyo VCSEL (laysarka tooska ah ee dusha sare ee daloolka).Kuwa soo socda ayaa lagu sharaxay dhinacyadan ee mabda'a lasers tunable.

Codsiga isgaarsiinta indhaha

Laser Tunable waa aaladda muhiimka ah ee optoelectronic jiil cusub oo ah nidaamka isku dhufashada mawjada dhererka cufan iyo isweydaarsiga sawir-qaadista ee dhammaan shabakadaha indhaha.Codsigeedu wuxuu si weyn u kordhiyaa awoodda, dabacsanaanta iyo scalability ee nidaamka gudbinta fiber indhaha, oo wuxuu xaqiiqsaday hagaajin joogto ah ama tiro-joogto ah oo baaxad ballaaran oo dhererka dhererka.
Shirkadaha iyo hay'adaha cilmi-baarista ee adduunka ayaa si firfircoon u kor u qaadaya cilmi-baarista iyo horumarinta lasers-ka, iyo horumarka cusub ayaa si joogto ah looga sameeyaa goobtan.Waxqabadka lasers tunable si joogto ah ayaa loo wanaajiyaa kharashkuna si joogto ah ayaa loo dhimay.Waqtigan xaadirka ah, laser-ka la isku hagaajin karo ayaa inta badan loo qaybiyaa laba qaybood: semiconductor tunable lasers iyo lasers fiber tunable.
Laysarka semiconductorwaa isha iftiinka muhiimka ah ee nidaamka isgaarsiinta indhaha, kaas oo leh sifooyinka cabbirka yar yar, miisaanka fudud, waxtarka beddelka sare, badbaadinta awoodda, iwm, waana sahlan tahay in la gaaro hal chip optoelectronic isdhexgalka qalabka kale.Waxaa loo qaybin karaa laser jawaab celin la qaybsan karo, la qaybiyey Bragg muraayad laser, nidaamka micromotor dusha dalool toosan oo sii deynaya leysarka dalool dibadda ah.
Horumarinta laser fiber tunable sida dhexdhexaad ah faa'iido iyo horumarinta ee semiconductor laser diode sida il bamka ayaa si weyn kor u qaaday horumarinta lasers fiber.Laysarka la hagaajin karo wuxuu ku salaysan yahay 80nm faa'iidada faa'iidada fibre-ga doped, iyo element filter ayaa lagu daraa loop si loo xakameeyo mawjada lasing oo loo ogaado hagaajinta hirarka dhererka.
Horumarinta laser semiconductor tunable waa mid aad u firfircoon adduunka, iyo horumarka sidoo kale waa mid aad u degdeg ah.Maaddaama laysarka la hagaajin karo ay si tartiib tartiib ah ugu dhowaanayaan mawjadaha mawjadaha dhererka go'an marka loo eego qiimaha iyo waxqabadka, waxaa lama huraan ah in aad iyo aad u badan loogu isticmaali doono nidaamyada isgaarsiinta waxayna door muhiim ah ka ciyaaraan mustaqbalka dhammaan shabakadaha indhaha.

Rajada horumarka
Waxaa jira noocyo badan oo leyser-dhareed ah, kuwaas oo guud ahaan lagu horumariyo iyadoo la sii kordhinayo hababka hagaajinta hirarka dhererka dhererka iyadoo lagu saleynayo leysarka kala duwan ee hal-mawjadaha dheereeya, iyo badeecadaha qaar ayaa suuqa loo keenay si caalami ah.Waxa kale oo la soo tebiyay horumarinta leysarka indhaha ee joogtada ah, lasers tunable oo leh hawlo kale oo isku dhafan ayaa sidoo kale la soo sheegay, sida laser tunable oo lagu dhex daray hal jajab oo VCSEL ah iyo modulator nuugista korantada, iyo laysarka oo lagu daray muunad grating Bragg reflector. iyo cod-weyneeye indho-sarcaad ah iyo qalab koronto oo nuugista ah.
Sababtoo ah laser-ka-mawjadaha-mawjadaha-mawjadaha ayaa si ballaaran loo isticmaalaa, laser-ka-habboon ee qaabab kala duwan ayaa lagu dabaqi karaa nidaamyo kala duwan, mid walbana wuxuu leeyahay faa'iidooyin iyo faa'iido darrooyin.Laysarka saqafka sare ee godka dibadda waxaa loo isticmaali karaa ila iftiin ballaaran oo la isku hagaajin karo oo ku jira aaladaha tijaabada saxda ah sababtoo ah awooddeeda sare ee wax soo saarka iyo hirarka dhererka ee joogtada ah.Marka laga eego dhinaca is dhexgalka photon iyo la kulanka mustaqbalka dhammaan shabakadaha indhaha, muunad grating DBR, grating heer sare ah oo DBR ah iyo leysarka la hagaajin karo oo lagu dhex daray modulators iyo amplifiers ayaa laga yaabaa inay yihiin ilo iftiin la hagaajin karo oo Z ah.
Fiber grating laser tunable oo leh dalool dibadda ah sidoo kale waa nooc rajo leh oo il iftiin ah, kaas oo leh qaab-dhismeed fudud, ballac xariiqa cidhiidhi ah iyo isku xidhka fiber fudud.Haddii modulator-ka EA lagu dhex milmi karo godka, waxa kale oo loo isticmaali karaa il soliton indhaha xawaaraha sare leh.Intaa waxaa dheer, leysarka fibre-gaab ee la hagaajin karo ee ku saleysan laysarka fiber-ka ayaa sameeyay horumar la taaban karo sanadihii ugu dambeeyay.Waxaa la filan karaa in waxqabadka lasers-tunable ee ilaha iftiinka isgaadhsiinta indhaha la sii wanaajin doono, iyo saamiga suuqa ayaa si tartiib tartiib ah u kordhi doona, oo leh rajooyin codsi oo aad u ifaya.
