Niki semiconductor optique amplifier

Niki asemiconductor optique amplifier

Amashanyarazi ya semiconductor optique ni ubwoko bwa optique ya optique ikoresha igice cya kabiri cyunguka. Irasa na diode ya laser, aho indorerwamo kumpera yo hepfo isimbuzwa igice cyerekana igice. Itara ryibimenyetso ryanyujijwe muri semiconductor imwe-moderi ya waveguide. Ibipimo bya transvers ya waveguide ni micrometero 1-2 kandi uburebure bwayo buri kuri 0.5-2mm. Ubwoko bwa waveguide bufite aho bugarukira hamwe nigikorwa gikora (amplification), kivomwa nubu. Umuyoboro winjizwamo utanga icyerekezo runaka cyabatwara mumurongo wogutwara, bigatuma inzira ihinduka ya bande ya bande kuri bande ya valence. Kwiyongera kwimpanuka bibaho mugihe ingufu za fotone ziruta gato ingufu za bandgap. SOA optique amplifier ikoreshwa muburyo bwa sisitemu yitumanaho muburyo bwingurube, hamwe nuburebure bwumurongo wa 1300nm cyangwa 1500nm, bitanga hafi 30dB yinyungu.

UwitekaSOA semiconductor optique amplifierni PN ihuza igikoresho hamwe na kwant kwingirakamaro neza. Inyuma yimbere ibogamye ihindura umubare wibice bya dielectric. Nyuma yumucyo wo kwishima hanze winjiye, imirasire ikangura irabyara, igera kumyongera yibimenyetso bya optique. Inzira zose uko ari eshatu zavuzwe haruguru zirahariSOA optique amplifier. Kwiyongera kw'ibimenyetso bya optique bishingiye ku myuka ihumanya ikirere. Kwinjira kwimyuka no kubyuka bihumanya bibaho icyarimwe. Kwinjiza kwinshi kumatara ya pompe birashobora gukoreshwa kugirango byihute kugarura abatwara, kandi mugihe kimwe, pompe yamashanyarazi irashobora kohereza electron murwego rwo hejuru (bande ya conduction). Iyo imirasire itunguranye yongerewe imbaraga, izakora urusaku rwinshi rwimishwarara. ‍SOA optique amplifier ishingiye kuri chip ya semiconductor.

Imashini ya Semiconductor igizwe na semiconductor ikomatanya, nka GaAs / AlGaAs, InP / AlGaAs, InP / InGaAsP na InP / InAlGaAs, nibindi nibindi nibikoresho byo gukora lazeri ya semiconductor. Igishushanyo mbonera cya SOA ni kimwe cyangwa gisa na laseri. Itandukaniro riri hagati yuko lazeri ikeneye gukora cavant ya resonant ikikije inyungu yunguka kugirango itange kandi ikomeze ihindagurika ryibimenyetso bya optique. Ibimenyetso bya optique bizongerwaho inshuro nyinshi mumyanya mbere yo gusohoka. MuriSOA amplifier. Imiterere ya amplifier ya SOA igizwe nibice bitatu: Agace P, Agace ka I (igorofa ikora cyangwa node), hamwe na N. Igice gisanzwe gikora kigizwe na kwantum Wells, zishobora kunoza imikorere yifoto no kugabanya umuvuduko winjira.

Igishushanyo 1 Fibre laser hamwe na SOA ihuriweho kugirango itange impiswi nziza

Byakoreshejwe kumuyoboro

SOAs ntabwo isanzwe ikoreshwa muburyo bwo kongera imbaraga gusa: irashobora no gukoreshwa mubijyanye no gutumanaho kwa fibre optique, porogaramu zishingiye kumurongo udafite umurongo nko kwiyongera kwuzuye cyangwa kwambukiranya ibice, ibyo bikaba bikoresha itandukaniro ryibintu bitwara abagenzi muri SOA optique amplifier kugirango babone ibimenyetso bitandukanye. Izi ngaruka zirashobora gukoreshwa muburyo bwo kwimura umuyoboro (guhinduranya umurongo), guhindura imiterere yo guhindura, kugarura isaha, kuvugurura ibimenyetso no kumenyekanisha imiterere, nibindi muri sisitemu yo kugabana imirongo myinshi.

Hamwe niterambere ryiterambere rya optoelectronic tekinoroji yumuzunguruko no kugabanya ibiciro byinganda, imirima ikoreshwa ya SOA semiconductor optique amplifier nkibikoresho byongera imbaraga, ibikoresho bya optique nibikoresho bya sisitemu bizakomeza kwaguka.
