Li-amplifiers tsa Optical tšimong ea puisano ea fiber ea optical
An amplifier ea mahloke sesebedisoa se hodisang matshwao a pono. Sebakeng sa puisano ea fiber ea optical, haholo-holo e bapala likarolo tse latelang: 1. Ho ntlafatsa le ho matlafatsa matla a optical. Ka ho beha amplifier ea optical karolong e ka pele ea transmitter ea optical, matla a optical a kenang fiber a ka eketseha. 2. Matlafatso ea relay ea inthaneteng, ho nkela li-Repeaters tse seng li ntse li le teng mekhoeng ea puisano ea fiber optical; 3. Kemiso ea pele: Pele ho photodetector qetellong ea ho amohela, lets'oao le fokolang la leseli le ntlafatsoa esale pele ho matlafatsa kutloisiso ea ho amohela.
Hona joale, li-amplifiers tsa Optical tse amoheloang ke puisano ea fiber ea Optical haholo-holo li kenyelletsa mefuta e latelang: 1. Semiconductor optical amplifier (SOA Optical amplifier)/Semiconductor laser amplifier (SLA Optical amplifier); 2. Li-amplifiers tse sa tloaelehang tsa lefats'e, joalo ka li-amplifiers tsa faeba tsa bait-doped.EDFA Optical amplifier), joalo-joalo.
1.Semiconductor optical amplifiers: Tlas'a maemo a fapaneng a kopo le ka ponahalo e fapaneng ea sefahleho sa ho qetela, lasers ea semiconductor e ka hlahisa mefuta e sa tšoaneng ea li-amplifiers tsa semiconductor optical. Haeba motlakase oa laser ea semiconductor o le tlase ho feta monyako oa oona, ke hore, ha ho na laser e hlahisoang, ka nako ena, pontšo ea optical e kenngoa pheletsong e le 'ngoe. Hafeela maqhubu a pontšo ena ea optical e le haufi le setsi sa spectral sa laser, e tla matlafatsoa le ho hlahisoa ho tloha pheletsong e 'ngoe. Mofuta ona oasemiconductor optical amplifiere bitsoa mofuta oa Fabry-Perrop amplifier optical (FP-SLA). Haeba laser e leeme ka holim'a monyako, letšoao le fokolang la mokhoa o le mong oa optical ho tloha pheletsong e 'ngoe, ha feela maqhubu a lets'oao lena la optical le le ka har'a sekhahla sa laser ena ea multimode, lets'oao la optical le tla holisoa le ho notleloa ka mokhoa o itseng. Mofuta ona oa amplifier oa optical o bitsoa amplifier ea mofuta oa injaction-locked (IL-SLA). Haeba lipheletsong tse peli tsa laser semiconductor li koahetsoe ka seipone kapa li fetoha mouoane ka lera la anti-reflection, e leng se etsang hore mouoane oa eona o be nyane haholo mme o se khone ho theha sekoti sa resonant sa Fabry-Perrow, ha lets'oao la optical le feta lera le sebetsang la waveguide, le tla holisoa ha le ntse le tsamaea. Ka hona, mofuta ona oa amplifier optical o bitsoa wave wave optical amplifier (TW-SLA), 'me sebopeho sa eona se bontšoa setšoantšong se latelang. Hobane bandwidth ea mofuta oa maqhubu a maqhubu a maqhubu a amplifier ke liodara tse tharo tse kholo ho feta tsa mofuta oa Fabry-Perot amplifier, mme bandwidth ea eona ea 3dB e ka fihla ho 10THz, e ka holisa mats'oao a maqhubu a fapaneng mme ke sehokelo sa mahlo se tšepisang haholo.
2. Fiber-doped fiber amplifier: E na le likarolo tse tharo: Ea pele ke fiber e nang le boea bo bolelele ho tloha ho limithara tse 'maloa ho ea ho mashome a limithara. Litšila tsena ke li-ion tsa lefats'e tse sa tloaelehang, tse etsang lisebelisoa tsa laser activation; Ea bobeli ke mohloli oa pompo ea laser, e fanang ka matla a bolelele ba maqhubu a loketseng ho hlasimolla li-ion tsa lefats'e tse sa tloaelehang e le ho fihlela khanya ea khanya. Ea boraro ke coupler, e nolofalletsang leseli la pompo le mabone a lets'oao hore a kopane ka har'a sesebelisoa se kenyang fiber optical. Molao-motheo o sebetsang oa amplifier ea fiber o tšoana haholo le oa laser e tiileng. E baka boemo bo fetotsoeng kabo ea linomoro ka har'a lisebelisoa tse kentsoeng ka laser mme e hlahisa mahlaseli a hlasimollang. Ho theha boemo bo tsitsitseng ba ho arola palo ea palo ea likaroloana, matla a fetang a mabeli a matla a lokela ho ameha phetohong ea optical, ka tloaelo litsamaiso tse tharo le tse 'nè, ka phepelo e tsoelang pele ea matla a tsoang mohloling oa pompo. E le ho fana ka matla ka katleho, bolelele ba pompo ea pompo e lokela ho ba bokhutšoanyane ho feta ba laser photon, ke hore, matla a pompo ea photon e lokela ho ba kholo ho feta ea laser photon. Ho feta moo, sekoti sa resonant se etsa maikutlo a nepahetseng, 'me kahoo ho ka thehoa amplifier ea laser.
3. Li-amplifiers tsa fiber tse se nang moeli: Ka bobeli li-amplifiers tse se nang moeli le li-erbium fiber amplifiers li oela tlas'a sehlopha sa li-fiber amplifiers. Leha ho le joalo, ea pele e sebelisa phello e sa tloaelehang ea likhoele tsa quartz, athe ea morao-rao e sebelisa likhoele tsa quartz tsa erbium-doped ho sebetsa mecheng ea litaba e sebetsang. Lithapo tse tloaelehileng tsa quartz optical fibers li tla hlahisa liphello tse matla tse se nang moeli tlas'a ketso ea khanya e matla ea pompo ea maqhubu a loketseng a maqhubu, joalo ka stimulated Raman scattering (SRS), stimulated Brillouin scattering (SBS), le liphello tse 'nè tsa ho kopanya maqhubu. Ha letšoao le fetisoa hammoho le fiber ea optical hammoho le leseli la pompo, leseli la pontšo le ka matlafatsoa. Ka hona, ba theha li-amplifiers tsa fiber Raman (FRA), Brillouin amplifiers (FBA), le li-amplifiers tsa parametric, tseo kaofela e leng li-fiber amplifiers tse ajoang.
Kakaretso: Tataiso e tloaelehileng ea nts'etsopele ea li-amplifiers tsohle tsa optical ke phaello e phahameng, matla a phahameng a tsoang, le palo e tlase ea lerata.
