Amashanyarazi meza muburyo bwa optique ya fibre itumanaho

An amplifierni igikoresho cyongera ibimenyetso bya optique. Mu rwego rwitumanaho rya fibre optique, ikina cyane cyane inshingano zikurikira: 1. Kuzamura no kongera imbaraga za optique. Mugushira amplifier optique kumpera yimbere ya transmitter ya optique, imbaraga za optique zinjira muri fibre zirashobora kwiyongera. 2. 3. Kwibanziriza: Mbere ya fotodetekeri kumpera yakira, ikimenyetso cyumucyo kidakomeye cyongeweho mbere kugirango cyongere kwiyakira.

Kugeza ubu, Optical amplifiers yemewe mu itumanaho rya fibre optique ikubiyemo ubwoko bukurikira: 1. Semiconductor optique amplifier (SOA Optical amplifier) / Semiconductor laser amplifier (SLA Optical amplifier); .EDFA Amashanyarazi meza), nibindi 3. Amashanyarazi ya fibre idafite umurongo, nka fibre Raman amplifier, nibindi bikurikira nintangiriro ngufi.

1.Semiconductor optique amplificateur: Mubihe bitandukanye byo gusaba kandi hamwe no kwerekana isura itandukanye yo mumaso, laseri ya semiconductor irashobora kubyara ubwoko butandukanye bwa semiconductor optique amplifier. Niba ikinyabiziga kigenda cya semiconductor laser kiri munsi yurwego rwacyo, ni ukuvuga ko nta lazeri ikorwa, muriki gihe, ibimenyetso bya optique byinjira kumpera imwe. Igihe cyose inshuro zibi bimenyetso bya optique biri hafi yikigo cya laser, bizongerwaho kandi bisohoke bivuye kurundi ruhande. Ubu bwokosemiconductor optique amplifieryitwa Fabry-Perrop ubwoko bwa optique amplifier (FP-SLA). Niba lazeri ibogamye hejuru yurugero, intege nke yuburyo bumwe bwa optique yinjiza kuva kumpera imwe, mugihe cyose inshuro zibi bimenyetso bya optique biri murwego rwiyi lazeri ya multimode, ibimenyetso bya optique bizongerwaho kandi bifungwe muburyo runaka. Ubu bwoko bwa optique amplifier bwitwa injaction-ifunze ubwoko bwa amplifier (IL-SLA). Niba impera zombi za lazeri ya semiconductor zometseho indorerwamo cyangwa zigahumeka hamwe na firime yo kurwanya anti-reaction, bigatuma emissivité yayo iba nto cyane kandi idashobora gukora cavity ya Fabry-Perrow, mugihe ibimenyetso bya optique byanyuze murwego rukora umurongo wa waveguide, bizongerwa mugihe cyurugendo. Kubwibyo, ubu bwoko bwa optique amplifier bwitwa ingendo yingendo ya optique amplifier (TW-SLA), kandi imiterere yayo irerekanwa mumashusho akurikira. Kuberako umurongo wubwoko bwurugendo rwubwoko bwa optique amplifier ni ordre eshatu zubunini buruta ubw'ubwoko bwa Fabry-Perot, kandi umurongo wa 3dB ushobora kugera kuri 10THz, urashobora kwongerera ibimenyetso bya optique ya radiyo zitandukanye kandi ni ibyiringiro byiza bya optique.

2. Bait-dope fibre amplifier: Igizwe nibice bitatu: Iya mbere ni fibre doped ifite uburebure buri hagati ya metero nyinshi na metero mirongo. Iyi myanda ni cyane cyane ion yisi idasanzwe, ikora ibikoresho byo gukora laser; Iya kabiri ni isoko ya pompe ya laser, itanga ingufu z'uburebure bukwiye kugirango ishimishe isi idasanzwe idasanzwe kugirango igere kumurabyo. Icya gatatu ni kuperi, ituma pompe yumucyo hamwe numucyo wibimenyetso kubashakanye muri doped optique fibre ikora ibikoresho. Ihame ryakazi rya fibre amplifier irasa cyane niya lazeri ikomeye. Itera ihindagurika ryimibare ikwirakwizwa ryimiterere mubintu bikoreshwa na laser kandi ikabyara imirasire ikangura. Kugirango habeho igipimo gihamye cyimibare ihindagurika, leta zirenze ebyiri zigomba kugira uruhare muguhinduka kwa optique, mubisanzwe urwego rwinzego eshatu ninzego enye, hamwe nogukomeza gutanga ingufu zituruka kumasoko ya pompe. Kugirango utange ingufu neza, uburebure bwumurongo wa pompe ya pompe bigomba kuba bigufi kurenza ibya foteri ya laser, ni ukuvuga ko ingufu za pompe ya pompe zigomba kuba nyinshi kuruta izifoto ya laser. Byongeye kandi, resonant cavity ikora ibitekerezo byiza, bityo hashobora kubaho laser amplifier.

3. Amashanyarazi ya fibre idafite umurongo: Byombi byongera fibre fibre hamwe na erbium fibre amplifier byinjira mubyiciro byongera fibre. Nyamara, iyambere ikoresha ingaruka zidafite umurongo wa fibre ya quartz, mugihe iyanyuma ikoresha erbium-dope ya quartz fibre kugirango ikore mubitangazamakuru bikora. Fibre isanzwe ya quartz optique izatanga ingaruka zikomeye zidafite umurongo mugikorwa cyurumuri rukomeye rwa pompe yuburebure bukwiye, nka Raman ikwirakwizwa (SRS), itera Brillouin ikwirakwiza (SBS), hamwe ningaruka zivanze n’imivumba ine. Iyo ibimenyetso byanyujijwe kuri fibre optique hamwe nu mucyo wa pompe, urumuri rwibimenyetso rushobora kwiyongera. Niyo mpamvu, bakora fibre Raman amplifier (FRA), Brillouin amplifier (FBA), hamwe na amplificateur ya parametric, byose bigabanywa fibre amplifier.

Incamake: Icyerekezo rusange cyiterambere cyibikoresho byose byongera inyungu ni inyungu nyinshi, imbaraga zisohoka cyane, hamwe n urusaku ruke.
