Nigutesemiconductor optique amplifierKugera kuri amplification?

Nyuma yigihe cyigihe cyitumanaho rinini rya optique ya fibre itumanaho, tekinoroji ya optique ya optique yateye imbere byihuse.Amashanyarazi mezaongera ibimenyetso byinjiza optique bishingiye kumirasire ikangutse cyangwa ikwirakwizwa. Ukurikije ihame ryakazi, amplificateur optique irashobora kugabanywa muri semiconductor optique amplifier (SOA) naoptique ya fibre optique. Muri bo,semiconductor optique amplifierByakoreshejwe cyane mu itumanaho rya optique bitewe ninyungu zo kunguka kwagutse, guhuza neza hamwe nuburebure bwumurongo. Zigizwe n'uturere dukora kandi tworoshye, kandi akarere gakora ni akarere kunguka. Iyo ikimenyetso cyumucyo kinyuze mukarere gakora, bitera electron gutakaza ingufu hanyuma zigasubira mubutaka muburyo bwa fotone, zifite uburebure bwumuraba nkikimenyetso cyumucyo, bityo bikongerera ibimenyetso byurumuri. Semiconductor optique amplifier ihindura umwikorezi wa semiconductor mubice byinyuma byumuvuduko wogutwara, byongerera imbaraga amplitude yumucyo watewe, kandi bikagumana ibimenyetso byingenzi biranga urumuri rwimbuto rwatewe nka polarisiyasi, ubugari bwumurongo ninshuro. Hamwe no kwiyongera kwimirimo ikora, ibisohoka optique nayo yiyongera mubikorwa runaka bikora.

Ariko iri terambere ntirigira imipaka, kuko semiconductor optique amplificateur ifite inyungu zuzuye. Ikintu cyerekana ko iyo imbaraga za optique zinjiza zihoraho, inyungu ziyongera hamwe no kwiyongera kwabashitsi batewe inshinge, ariko mugihe ubwikorezi bwatewe inshinge ari nini cyane, inyungu izuzura cyangwa igabanuke. Iyo kwibumbira hamwe kwabatwara inshinge bihoraho, imbaraga zisohoka ziyongera hamwe no kwiyongera kwingufu zinjiza, ariko iyo ingufu za optique zinjiza ari nini cyane, igipimo cyikoreshwa ryabatwara giterwa nimirasire ishimishije ni kinini cyane, bikaviramo kwiyuzuzamo cyangwa kugabanuka. Impamvu yo kunguka ibintu byuzuye ni imikoranire hagati ya electron na fotone mubikoresho byakarere bikora. Yaba fotone yabyaye inyungu zunguka cyangwa fotone yo hanze, umuvuduko imirasire ikangura itwara abayitwara ifitanye isano nigipimo abayitwara buzuza kurwego rwingufu zijyanye mugihe. Usibye imirasire ikangurwa, igipimo cyabatwara gikoreshwa nibindi bintu nacyo kirahinduka, bigira ingaruka mbi kubwuzuye.

Kubera ko umurimo wingenzi wa semiconductor optique amplificateur ari uguhuza umurongo, cyane cyane kugirango ugere kuri amplification, irashobora gukoreshwa nkibikoresho byongerera ingufu, umurongo wongerera imbaraga hamwe na preamplifiers muri sisitemu yitumanaho. Ku ihererekanyabubasha, semiconductor optique amplifier ikoreshwa nkimbaraga zongerera imbaraga imbaraga kugirango zongere imbaraga ziva kumpera ya sisitemu, zishobora kongera cyane intera yerekana intera yumurongo wa sisitemu. Mu murongo wohereza, igice cya semiconductor optique amplifier irashobora gukoreshwa nkumurongo wa relay amplifier, kugirango intera yohereza imiyoboro irashobora kongera kwaguka no gusimbuka. Ku iherezo ryakiriwe, semiconductor optique amplifier irashobora gukoreshwa nka preamplifier, ishobora kuzamura cyane ibyiyumvo byabakiriye. Inyungu yuzuye yibiranga semiconductor optique amplifier bizatera inyungu kuri buri kintu kijyanye na biti yabanjirije. Ingaruka yicyitegererezo hagati yimiyoboro mito irashobora nanone kwitwa cross-gain modulation effect. Ubu buhanga bukoresha impuzandengo y'ibarurishamibare yingaruka zinyuranye zo guhinduranya hagati yimiyoboro myinshi kandi itangiza ubukana buciriritse bukomeza murwego rwo gukomeza urumuri, bityo bikagabanya inyungu zose ziyongera. Noneho ingaruka zinyuranye zo guhinduranya hagati yimiyoboro iragabanuka.

Semiconductor optique amplifier ifite imiterere yoroshye, guhuza byoroshye, kandi irashobora kongera ibimenyetso bya optique yuburebure butandukanye, kandi bikoreshwa cyane muguhuza ubwoko butandukanye bwa laseri. Kugeza ubu, tekinoroji yo guhuza laser ishingiye kuri semiconductor optique amplifier ikomeza gukura, ariko haracyakenewe imbaraga mubice bitatu bikurikira. Imwe ni ukugabanya igihombo cyo guhuza hamwe na fibre optique. Ikibazo nyamukuru cya semiconductor optique amplifier nuko igihombo cyo guhuza hamwe na fibre ari kinini. Kugirango tunoze imikorere yo guhuza, lens irashobora kongerwamo sisitemu yo guhuza kugirango igabanye igihombo cyo gutekereza, kunoza uburinganire bwibiti, kandi bigerweho neza. Iya kabiri ni ukugabanya polarisiyasi yimikorere ya semiconductor optique amplifier. Ihindagurika rya polarisiyasi ahanini ryerekeza kuri polarisiyasi yumucyo wibyabaye. Niba semiconductor optique amplifier idakozwe muburyo budasanzwe, umurongo mugari winyungu uzagabanuka. Imiterere ya Quantum irashobora kunoza neza ituze rya semiconductor optique amplifier. Birashoboka kwiga imiterere yoroheje kandi isumba iyindi kugirango igabanye polarisiyasi ya semiconductor optique amplificateur. Icya gatatu ni ugutezimbere inzira ihuriweho. Kugeza ubu, guhuza semiconductor optique amplifier na laseri biragoye cyane kandi biragoye mugutunganya tekiniki, bikaviramo igihombo kinini mugukwirakwiza ibimenyetso bya optique no gutakaza ibikoresho, kandi ikiguzi ni kinini cyane. Kubwibyo, dukwiye kugerageza kunonosora imiterere yibikoresho byahujwe no kunoza neza ibikoresho.

Mubuhanga bwitumanaho rya optique, tekinoroji ya optique ni bumwe mu buhanga bufasha, kandi tekinoroji ya semiconductor optique amplifier iratera imbere byihuse. Kugeza ubu, imikorere ya semiconductor optique amplificateur yaratejwe imbere cyane cyane mugutezimbere tekinoloji nshya ya optique nka tekinike yuburebure bwa multiplexing cyangwa optique yo guhinduranya. Hamwe niterambere ryinganda zamakuru, tekinoroji ya optique ya amplification ikwiranye na bande zitandukanye hamwe nibikorwa bitandukanye bizatangizwa, kandi iterambere nubushakashatsi bwikoranabuhanga rishya byanze bikunze bizatuma tekinoroji ya semiconductor optique amplifier ikomeza gutera imbere no gutera imbere.
