E ntlafalitsoesemiconductor optical amplifier
Sesebelisoa se ntlafalitsoeng sa semiconductor optical amplifier ke mofuta o ntlafalitsoeng oa semiconductor optical amplifier.SOA optical amplifier). Ke amplifier e sebelisang li-semiconductors ho fana ka mokhoa oa ho fumana. Sebopeho sa eona se tšoana le sa laser diode ea Fabry-Pero, empa hangata sefahleho sa ho qetela se koahetsoe ka filimi e khahlanong le ho bonahatsa. Moralo oa morao-rao o kenyelletsa lifilimi tse khahlanong le ho bonahatsa hammoho le li-waveguides tse sekametseng le libaka tsa lifensetere, tse ka fokotsang ponahalo ea sefahleho sa ho qetela ho ea ka tlase ho 0.001%. Li-amplifiers tsa optical tse ntlafatsang ts'ebetso e phahameng li na le thuso ka ho khetheha ha ho phahamisa matšoao (optical), kaha ho na le tšokelo e tebileng ea tahlehelo ea matšoao nakong ea phetisetso ea nako e telele. Kaha lets'oao la optical le matlafalitsoe ka kotloloho, mokhoa oa setso oa ho o fetola lets'oao la motlakase pele o fetoha o sa hlokahaleng. Ka hona, tšebeliso eaSOAe ntlafatsa haholo ts'ebetso ea phetisetso. Theknoloji ena e atisa ho sebelisoa bakeng sa karohano ea matla le matšeliso a tahlehelo ho marang-rang a WDM.
Maemo a kopo
Litsamaisong tsa puisano tsa fiber optical, li-amplifiers tsa semiconductor optical (SOA) li ka sebelisoa libakeng tse ngata tsa kopo ho ntlafatsa sebaka sa ts'ebetso le phetisetso ea sistimi ea puisano. Lintlha tse latelang ke tse ling tse tloaelehileng tsa ho sebelisa SOA amplifier ho optical fiber communication systems:
Preamplifier: SOAamplifier ea mahloe ka sebelisoa e le preamplifier pheletsong ea ho amohela optical lits'ebetsong tsa puisano tsa sebaka se selelele tse nang le likhoele tsa optical tse fetang lik'hilomithara tse 100, ho matlafatsa kapa ho matlafatsa matla a tlhahiso ea lets'oao lits'ebetsong tsa puisano tse telele tsa optical fiber, ka hona ho lefella sebaka se sa lekaneng sa phetisetso se bakoang ke tlhahiso e fokolang ea matšoao a manyane. Ho feta moo, SOA e ka boela ea sebelisoa ho kenya ts'ebetsong thekenoloji ea optical network signal regeneration ka optical fiber communication systems.
Tsosoloso ea mats'oao a mats'oao: Ka marang-rang a optical, ha sebaka sa phetisetso se ntse se eketseha, matšoao a optical a tla senyeha ka lebaka la ho fokotseha, ho qhalakanngoa, lerata, jitter ea nako le crosstalk, joalo-joalo, joalo-joalo, ka phetiso ea nako e telele, hoa hlokahala ho lefella tlhahisoleseling e senyehileng ea optical ho netefatsa ho nepahala ha transmitted. Tsosoloso ea mats'oao a mahlo-mafubelu e bolela ho holisa bocha, ho bopa bocha le ho lokisa nako. Ho holisa ho eketsehileng ho ka finyelloa ka li-amplifiers tsa optical tse kang semiconductor optical amplifiers, EDFA le Raman amplifiers (RFA).
Lits'ebetsong tsa optical fiber sensing, li-amplifiers tsa semiconductor optical (SOA amplifier) e ka sebelisoa ho holisa matšoao a optical, ka hona ho matlafatsa kutlo le ho nepahala ha li-sensor. Lintlha tse latelang ke tse ling tse tloaelehileng tsa ho sebelisa SOA lits'ebetsong tsa optical fiber sensing:
Tekanyo ea khatello ea fiber ea optical: Lokisa fiber ea optical holim'a ntho eo khatello ea eona e lokelang ho lekanngoa. Ha ntho e le tlas'a khatello, phetoho ea khatello e tla etsa hore ho be le phetoho e nyenyane bolelele ba fiber optical, kahoo e fetola bolelele ba nako kapa nako ea pontšo ea optical ho PD sensor. SOA amplifier e ka fihlela ts'ebetso e phahameng ea kutlo ka ho holisa le ho sebetsana le lets'oao la optical.
Tekanyo ea khatello ea optical fiber: Ka ho kopanya likhoele tsa optical le lisebelisoa tse thibelang khatello, ha ntho e le tlas'a khatello, e tla baka liphetoho ho lahleheloa ke optical ka har'a fiber optical. SOA e ka sebelisoa ho matlafatsa lets'oao lena le fokolang la optical ho fihlela tekanyo ea khatello e matla haholo.
Semiconductor optical amplifier SOA ke sesebelisoa sa bohlokoa masimong a puisano ea optical fiber le optical fiber sensing. Ka ho holisa le ho sebetsana le matšoao a optical, e ntlafatsa ts'ebetso ea sistimi le kutlo ea kutlo. Lisebelisoa tsena li bohlokoa bakeng sa ho fihlella puisano e potlakileng, e tsitsitseng le e ts'epahalang ea fiber ea optical, hammoho le mokhoa o nepahetseng oa ho lemoha fiber.
