Yini ai-semiconductor optical amplifier
I-semiconductor optical amplifier iwuhlobo lweamplifier yokubona esebenzisa i-semiconductor gain medium. Kufana ne-laser diode, lapho isibuko esisekugcineni okuphansi sithathelwa indawo nge-semi-reflective coating. Ukukhanya kwesignali kudluliselwa nge-semiconductor yemodi eyodwa ye-waveguide. Ubukhulu obuguquguqukayo be-waveguide bungama-micrometer angu-1-2 futhi ubude bawo buyi-oda lika-0.5-2mm. Imodi ye-waveguide inokugqagqana okubalulekile nendawo esebenzayo (i-amplification), empontshwa amandla amanje. Umjovo wamanje ukhiqiza ukugxiliswa kwenkampani yenethiwekhi ethile kubhendi yokuqhuba, okuvumela ukuguqulwa kokubona kwebhendi yokuqhuba ukuya kubhendi ye-valence. Ukuzuza okuphezulu kwenzeka lapho amandla e-photon emakhulu kancane kunamandla we-bandgap. I-SOA optical amplifier isetshenziswa ngokujwayelekile ezinhlelweni zokuxhumana ngendlela ye-pigtails, enobude obusebenzayo obuzungeze u-1300nm noma u-1500nm, ihlinzeka cishe nge-30dB yenzuzo.
II-SOA semiconductor optical amplifieriyithuluzi lokuhlanganisa le-PN elinesakhiwo somthombo we-strain quantum. Ukuchema kwangaphandle kwangaphandle kubuyisela emuva inani lezinhlayiya ze-dielectric. Ngemva kokungena kokukhanya okuvusa amadlingozi kwangaphandle, imisebe evuselelwe ikhiqizwa, ifinyelela ukukhuliswa kwamasignali optical. Zonke lezi zinqubo ezintathu ezingenhla zokudlulisa amandla zikhonaI-SOA Optical amplifier. Ukukhulisa amasignali optical kusekelwe ekukhishweni okukhuthazwayo. Izinqubo zokumuncwa okukhuthazwayo kanye nezinqubo zokukhishwa ezikhuthazwayo zikhona ngesikhathi esisodwa. Ukumuncwa okukhuthazwa kokukhanya kwepompo kungasetshenziswa ukusheshisa ukutholwa kwabathwali, futhi ngesikhathi esifanayo, iphampu kagesi ingathumela ama-electron ezingeni eliphezulu lamandla (ibhendi yokuqhuba). Lapho imisebe ezenzakalelayo ikhuliswa, izokwakha umsindo wemisebe ozenzakalelayo okhulisiwe. Iamplifier ye-SOA isekelwe kuma-semiconductor chips.
Ama-semiconductor chips akhiwe ngama-semiconductors ayinhlanganisela, njenge-GaAs/AlGaAs, i-InP/AlGaAs, i-InP/InGaAsP kanye ne-InP/InAlGaAs, njll. Lezi futhi izinto zokwenza ama-semiconductor laser. Idizayini ye-waveguide ye-SOA iyafana noma ifana neyama-lasers. Umehluko ulele ekutheni amalaser adinga ukwakha i-resonant cavity eduze kwendawo yokuthola ukuze akhiqize futhi agcine ukuzungeza kwesignali yokubona. Isignali yokubona izokhuliswa izikhathi eziningi ku-cavity ngaphambi kokukhishwa. KuI-amplifier ye-SOA(esixoxa ngakho lapha kukhawulelwe kuzikhulisamandla zamagagasi ezihambayo ezisetshenziswa ezinhlelweni eziningi), ukukhanya kudinga kuphela ukudlula endaweni yokuthola kanye, futhi ukubhekela emuva kuncane. Isakhiwo se-SOA amplifier siqukethe izindawo ezintathu: Indawo P, Indawo I (ungqimba olusebenzayo noma i-node), kanye ne-Area N. Isendlalelo esisebenzayo ngokuvamile sihlanganiswe ne-quantum Wells, engathuthukisa ukusebenza kahle kokuguqulwa kwe-photoelectric futhi inciphise umkhawulo wamanje.
Umfanekiso we-1 Fiber laser ene-SOA ehlanganisiwe yokukhiqiza ama-pulses optical
Kufakwe ekudluliselweni kwesiteshi
Ama-SOA ngokuvamile awasetshenziswa kuphela ekukhuliseni: angasetshenziswa futhi emkhakheni wokuxhumana kwe-fiber optical, izinhlelo zokusebenza ezisekelwe ezinkambisweni ezingezona ze-linear ezifana nokuzuza kokugcwala noma i-cross-phase polarization, esebenzisa ukuhluka kwe-concentration ye-carrier ku-SOA optical amplifier ukuze kutholwe indices ehlukahlukene ye-refractive. Le miphumela ingasetshenziswa ekudlulisweni kwesiteshi (ukuguqulwa kwe-wavelength), ukuguqulwa kwefomethi ye-modulation, ukutakula kwewashi, ukuvuselelwa kwesignali nokuqashelwa kwephethini, njll. ezinhlelweni zokuphindaphinda kwe-wavelength division multiplexing.
Ngokuthuthuka kobuchwepheshe besifunda obuhlanganisiwe be-optoelectronic kanye nokwehliswa kwezindleko zokukhiqiza, izinkambu zokufaka isicelo ze-SOA semiconductor optical amplifier njengama-amplifiers ayisisekelo, amadivaysi optical asebenzayo kanye nezingxenye ze-subsystem zizoqhubeka zanda.
