Amashanyarazi meza ya optique: Intangiriro kuri Semiconductor Optical Amplifier

Amashanyarazi mezaurukurikirane: Intangiriro kuri Semiconductor Optical Amplifier

Semiconductor optique amplifier(SOA) ni amplifier optique ishingiye kuri semiconductor yunguka itangazamakuru. Nubusanzwe ni nka fibre ihujwe na semiconductor laser tube, hamwe nindorerwamo yanyuma isimburwa na firime irwanya; Umuhengeri uhengamye urashobora gukoreshwa kugirango ugabanye impera yanyuma. Itara ry'ikimenyetso risanzwe ryanduzwa binyuze muri semiconductor imwe-imwe ya waveguide, hamwe nuburinganire bwa 1-2 μ m n'uburebure bwa 0.5-2mm. Ubwoko bwa waveguide burahuza cyane nakarere (amplification) akarere, kavomwe nubu. Gutera inshinge zitanga ubwinshi bwabatwara mumurongo wogutwara, bigatuma habaho impinduka nziza kuva mumashanyarazi kugeza kumurongo wa valence. Inyungu ntarengwa iboneka kuri ingufu za fotone hejuru gato yingufu za bandgap.

Ihame ryakazi rya semiconductor optique amplifier
Semiconductor optique amplifier (SOA) kongera ibimenyetso byerekana urumuri binyuze mubyuka bihumanya ikirere, kandi uburyo bwabo burasa nubwa lazeri ya semiconductor.SOA optique amplifierni lazeri ya semiconductor gusa idafite ibitekerezo, kandi intandaro yayo ni ukubona inyungu nziza muguhindura umubare wibice iyo amplifier ya semiconductor optique cyangwa amashanyarazi.
Ubwoko bwaSOA Semiconductor optique amplifier
Ukurikije uruhare SOA yagize muri sisitemu yabakiriya, barashobora kugabanywamo ibyiciro bine: serial, booster, guhinduranya SOA, na preamplifier.
1. Kwinjiza mu buryo butaziguye: inyungu nyinshi, Psat iringaniye; Hasi NF na PDG yo hepfo, mubisanzwe bifitanye isano na polarisiyasi yigenga SOA ·
2. Kuzamura: Psat Yisumbuye, inyungu yo hasi, mubisanzwe biterwa na polarisiyasi;
3. Hindura: igipimo kinini cyo kuzimangana no kuzamuka vuba / kugwa;
4. Pre amplifier: ibereye intera ndende, NF yo hasi, ninyungu nyinshi.
Ibyiza bya SOA Semiconductor optique amplifier
Inyungu ya optique itangwa na SOA mumurongo mugari irigenga kuburebure bwumurongo wibimenyetso bya optique.
Injiza amashanyarazi nkikimenyetso cya pompe yongerewe, aho kuvoma neza.
Bitewe nubunini bwacyo, SOA irashobora guhuzwa nibikoresho byinshi bya fotonike ya fotonike kumurongo umwe wa planari.
4. Bakoresha tekinoroji imwe na lazeri ya diode.
SOA irashobora gukora mumirongo yitumanaho ya 1300 nm na 1550 nm, hamwe numuyoboro mugari (kugeza 100 nm).
6. Birashobora gushyirwaho no guhuzwa kugirango bikore nkibisobanuro kuri optique yakira.
SOA irashobora gukoreshwa nkirembo ryoroshye rya logique mumashanyarazi ya WDM.

Imipaka ya SOA Semiconductor optique amplifier
SOA irashobora gutanga ingufu za optique zingana na miliwatt icumi (mW), mubisanzwe birahagije kubikorwa byumuyoboro umwe mumikorere ya fibre optique. Nyamara, sisitemu ya WDM irashobora gusaba ingufu zingana na mW nyinshi kumuyoboro.
2. Bitewe no guhuza fibre optique yinjiza no hanze ya SOA chip ihuriweho akenshi itera gutakaza ibimenyetso, SOA igomba gutanga inyungu zinyongera kugirango igabanye ingaruka ziki gihombo kubintu byinjira / bisohoka mukarere gakorera.
SOA yunvikana cyane na polarisiyasi yinjiza ibimenyetso bya optique.
4. Zibyara urusaku rwinshi mubitangazamakuru bikora kuruta fibre fibre.
Niba imiyoboro myinshi ya optique yongerewe imbaraga nkuko bikenewe muri porogaramu ya WDM, SOA izatera inzira ikomeye.
