Amplifier ea mahloletoto: Selelekela ho Semiconductor Optical Amplifier
Semiconductor optical amplifier(SOA) ke amplifier ea optical e thehiloeng ho semiconductor gain media. Ha e le hantle e tšoana le fiber e kopantsoeng le semiconductor laser tube, le seipone sa ho qetela se nkeloe sebaka ke filimi e khahlanong le ho bonahatsa; Li-waveguides tse tilted li ka sebelisoa ho fokotsa ts'ebetso ea ho qetela. Leseli la pontšo hangata le fetisoa ka semiconductor single-mode waveguide, e nang le lateral dimension ea 1-2 μ m le bolelele ba hoo e ka bang 0.5-2mm. Mokhoa oa waveguide o fetana haholo le sebaka se sebetsang (amplification), se pompetsoeng ke hona joale. Ente hona joale e hlahisa sekhahla se itseng sa mopalami ka har'a sehlopha sa conduction, se lumellang phetoho ea optical ho tloha sehlopheng sa conduction ho ea sehlopheng sa valence. Phaello e phahameng ka ho fetisisa e etsahala ho matla a photon hanyenyane ka holim'a matla a bandgap.
Molao-motheo o sebetsang oa semiconductor optical amplifier
Semiconductor optical amplifiers(SOA) holisa mats'oao a mabone a ketsahalo ka tlhahiso e hlasimollang, 'me mochine oa bona o tšoana le oa lasers ea semiconductor.SOA optical amplifiere mpa e le laser ea semiconductor ntle le maikutlo, 'me motheo oa eona ke ho fumana phaello ea mahlo ka ho khutlisetsa morao palo ea likaroloana ha semiconductor optical amplifier e pompa ka mokhoa oa optically kapa oa motlakase.
Mefuta eaSOA Semiconductor Optical amplifier
Ho ea ka karolo e phethoang ke SOA litsamaisong tsa bareki, li ka aroloa ka mekhahlelo e mene: serial, booster, switching SOA, le preamplifier.
1. Ho kenya ka ho toba: phaello e phahameng, Psat e itekanetseng; NF e tlase le PDG e tlase, hangata e amahanngoa le polarization e ikemetseng SOA·
2. Enhancer: Psat e phahameng, phaello e tlaase, hangata e itšetlehile ka polarization;
3. Switch: tekanyo e phahameng ea ho timela le nako ea ho phahama / ho oa ka potlako;
4. Pre amplifier: e loketse sebaka se selelele sa phetisetso, NF e tlase, le phaello e phahameng.
Melemo ea SOA Semiconductor optical amplifier
Phaello ea optical e fanoang ke SOA ka har'a bandwidth e batla e ikemetse ka bolelele ba leqhubu la ketsahalo ea optical signal.
Ente hona joale e le pontšo ea pompo e matlafalitsoeng, ho e-na le ho pompa ka mahlo.
Ka lebaka la boholo ba eona bo kopanetsoeng, SOA e ka kopanngoa le lisebelisoa tse ngata tsa photonic tsa waveguide ho substrate e le 'ngoe ea planar.
4. Ba sebelisa theknoloji e tšoanang le ea diode lasers.
SOA e ka sebetsa lihlopheng tsa spectral tsa puisano tsa 1300 nm le 1550 nm, ka bophara bo pharaletseng (ho fihlela ho 100 nm).
6. Li ka hlophisoa le ho kopanngoa ho sebetsa e le li-preamplifiers qetellong ea optical receiver.
SOA e ka sebelisoa e le heke e bonolo ea logic ho li-network tsa optical tsa WDM.
Meeli ea SOA Semiconductor optical amplifier
SOA e ka fana ka matla a optical a fihlang ho mashome a milliwatts (mW), ao hangata a lekaneng bakeng sa ts'ebetso ea mocha o le mong ho likhokahano tsa puisano tsa fiber optic. Leha ho le joalo, litsamaiso tsa WDM li ka hloka ho fihla ho li-mW tse 'maloa tsa matla ka mocha.
2. Ka lebaka la ho kopanngoa ha li-fibers tsa optical tse kenang le ho tsoa ho li-chips tse kopantsoeng tsa SOA tse atisang ho baka tahlehelo ea matšoao, SOA e tlameha ho fana ka phaello e eketsehileng ea optical ho fokotsa phello ea tahlehelo ena likarolong tsa ho kenya / lihlahisoa tsa sebaka se sebetsang.
SOA e ameha haholo ho polarization ea matšoao a optical input.
4. Li hlahisa maemo a phahameng a lerata mecheng ea litaba e sebetsang ho feta li-amplifiers tsa fiber.
Haeba liteishene tse ngata tsa optical li matlafatsoa ha ho hlokahala lits'ebetsong tsa WDM, SOA e tla baka crosstalk e matla.
