Qalabka kor u qaada ee indhaha ee ku jira isgaarsiinta fiber-ka indhaha
An kor u qaade indhaha ahwaa qalab xoojiya calaamadaha indhaha. Dhinaca isgaarsiinta fiber-ka indhaha, waxay inta badan qabataa doorarka soo socda: 1. Kobcinta iyo xoojinta awoodda indhaha. Iyadoo la dhigayo qalabka maqalka ee indhaha dhammaadka hore ee gudbiyaha indhaha, awoodda indhaha ee soo gasha fiber-ka waa la kordhin karaa. 2. Kororka gudbinta khadka tooska ah, oo lagu beddelayo kuwa ku celceliya ee jira nidaamyada isgaarsiinta fiber-ka indhaha; 3. Kordhinta Hore: Kahor sawir-qaadaha dhinaca dambe ee qaataha, calaamadda iftiinka ee daciifka ah ayaa horay loo sii xoojiyay si loo xoojiyo dareenka helitaanka.
Waqtigan xaadirka ah, qalabka kor u qaada maqalka ee loo isticmaalo isgaarsiinta fiber-ka indhaha waxaa inta badan ka mid ah noocyada soo socda: 1. Qalabka kor u qaada maqalka ee semiconductor (SOA amplifier indhaha)/Amplifier laser semiconductor (SLA Optical amplifier); 2. Amplifier-ro fiber ah oo naadir ah oo dhulka lagu dahaadhay, sida amplifier-ro fiber ah oo lagu dahaadhay dahaadhka (EDFA amplifier indhaha), iwm. 3. Qalab-sameeyayaasha fiber-ka ee aan tooska ahayn, sida qalab-sameeyayaasha fiber Raman, iwm. Kuwa soo socdaa waa hordhac kooban oo siday u kala horreeyaan.
1. Qalabka Korontada ee Semiconductor-ka: Xaaladaha kala duwan ee codsiga iyo iyadoo leh muuqaal weji oo kala duwan, laysarka semiconductor-ka waxay soo saari karaan noocyo kala duwan oo qalabka korontada ee semiconductor-ka ah. Haddii qulqulka wadista ee laysarka semiconductor-ka uu ka hooseeyo heerkiisa, taasi waa, wax laysar ah lama soo saaro, waqtigan, calaamad muuqaal ah ayaa la gelinayaa hal dhinac. Ilaa inta soo noqnoqoshada calaamaddan muuqaalku ay ku dhowdahay xarunta spectral-ka ee laysarka, waa la kordhin doonaa oo laga soo saari doonaa dhinaca kale. Noocan oo kale ahamplifier indhaha semiconductorwaxaa loogu yeeraa qalabka kor u qaada iftiinka nooca Fabry-Perrop (FP-SLA). Haddii laysarka uu ka leexan yahay heerka sare, gelinta calaamadaha indhaha ee hal-qaabka ah ee daciifka ah ee ka imanaya hal dhinac, ilaa inta soo noqnoqoshada calaamaddan indhaha ay ku jirto leysarkan badan ee qaabka badan leh, calaamadda indhaha ayaa la kordhin doonaa oo lagu xiri doonaa qaab gaar ah. Noocan qalabka kor u qaada iftiinka waxaa loo yaqaan qalabka kor u qaada iftiinka nooca qufulan ee la duray (IL-SLA). Haddii labada daraf ee laysarka semiconductor-ka ay muraayad ku dahaaran yihiin ama ay uumi baxaan lakab filim ka-hortagga milicsiga, taasoo ka dhigaysa iftiinkiisa mid aad u yar oo aan awoodin inuu sameeyo godka fabry-Perrow ee resonant, marka calaamadda indhaha ay dhex marto lakabka firfircoon ee hagaha hirarka, way sii weynaan doontaa inta la safrayo. Sidaa darteed, noocan qalabka kor u qaada iftiinka waxaa loo yaqaan qalabka kor u qaada iftiinka nooca socdaalka (TW-SLA), qaab-dhismeedkiisuna wuxuu ku muuqdaa sawirka soo socda. Sababtoo ah ballaca mugga qalabka dhawaaqa ee nooca hirarka safarka ah waa saddex amar oo cabbirkoodu ka weyn yahay kan qalabka dhawaaqa ee nooca Fabry-Perot, ballaca 3dB-na wuxuu gaari karaa 10THz, wuxuu xoojin karaa calaamadaha indhaha ee mawjadaha kala duwan waana qalab cod-weyneeye oo aad u rajo badan.
2. Amplifier-ka fiber-ka ee lagu dahaadhay: Waxa uu ka kooban yahay saddex qaybood: Tan koowaad waa faybar la dahaadhay oo dhererkeedu u dhexeeyo dhowr mitir ilaa tobanaan mitir. Wasakhyadani inta badan waa ion-yada dhulka ee naadirka ah, kuwaas oo sameeya walxaha kicinta laysarka; Tan labaad waa isha bamka laysarka, kaas oo bixiya tamar hirarka ku habboon si uu u kiciyo ion-yada dhulka ee naadirka ah ee la dahaadhay si loo gaaro ballaarinta iftiinka. Tan saddexaad waa isku-xidhka, kaas oo u suurtageliya iftiinka bamka iyo iftiinka calaamadda inay ku xidhmaan walxaha firfircoon ee fiber-ka indhaha ee la dahaadhay. Mabda'a shaqada ee amplifier-ka fiber-ka aad ayuu ula mid yahay tan laysarka xaaladda adag. Waxay keentaa xaalad qaybinta tirada walxaha ee la beddelay oo ku jirta walxaha laysarka ku shaqeeya waxayna soo saartaa shucaac la kiciyay. Si loo abuuro xaalad qaybinta tirada walxaha ee deggan, in ka badan laba heer oo tamar ah waa in lagu lug yeesho kala-guurka indhaha, badanaa nidaamyada saddex-heer iyo afar-heer, iyadoo la siinayo tamar joogto ah oo ka timaadda isha bamka. Si loo bixiyo tamar wax ku ool ah, hirarka photon-ka bamka waa inuu ka gaaban yahay tan photon-ka laysarka, taas oo ah, tamarta photon-ka bamka waa inay ka weynaataa tan photon-ka laysarka. Intaa waxaa dheer, godka dhawaaqa wuxuu sameeyaa jawaab celin wanaagsan, sidaas darteedna waxaa la samayn karaa qalab laysar ah.
3. Amplifiers-ka aan tooska ahayn ee fiber-ka: Labada amplifiers-ka aan tooska ahayn ee fiber-ka iyo amplifiers-ka erbium-ka waxay hoos yimaadaan qaybta amplifiers-ka fiber-ka. Si kastaba ha ahaatee, kan hore wuxuu adeegsadaa saameynta aan tooska ahayn ee fiber-ka quartz-ka, halka kan dambe uu adeegsado fiilooyinka quartz-ka erbium-ka lagu sameeyay si uu ugu dhaqmo warbaahinta firfircoon. Fiilooyinka indhaha ee quartz-ka caadiga ah waxay soo saari doonaan saameyn xooggan oo aan toos ahayn iyadoo la adeegsanayo iftiinka bamka xooggan ee hirarka ku habboon, sida Raman-ka la kiciyay (SRS), Brillouin-ka la kiciyay (SBS), iyo saamaynta isku-darka afar-hir. Marka calaamadda lagu gudbiyo fiilada indhaha oo ay weheliso iftiinka bamka, iftiinka calaamadda waa la kordhin karaa. Sidaas darteed, waxay sameeyaan amplifiers-ka fiber-ka Raman (FRA), Brillouin-ka la xoojiyay (FBA), iyo amplifiers-ka parametric, kuwaas oo dhammaantood ah amplifiers-ka fiber-ka la qaybiyay.
Soo Koobid: Jihada horumarinta guud ee dhammaan qalabka dhegaha-dhejiska ah waa faa'iido sare, awood wax soo saar sare, iyo shax buuq yar.
