Yintoni nasemiconductor optical amplifier
I-semiconductor optical amplifier luhlobo lweamplifier ye-optical esebenzisa i-semiconductor gain medium. Ifana ne-laser diode, apho isibuko esisezantsi sitshintshwe nge-semi-reflective coating. Ukukhanya komqondiso kuhanjiswa nge-semiconductor ye-single-mode waveguide. Ubungakanani obunqamlezileyo be-waveguide yi-1-2 micrometers kwaye ubude bayo buyi-0.5-2mm. Imowudi ye-waveguide ine-overlap ephawulekayo kunye nommandla osebenzayo (ukukhulisa), ophonswa ngokukhoyo. I-injected current ivelisa i-concentration ethile ye-carrier kwi-conduction band, evumela ukuguqulwa kwe-optical ye-conduction band ukuya kwi-valence band. Ukuzuza okuphezulu kwenzeka xa amandla efoton ekhulu kancinci kunamandla e-bandgap. I-SOA yeamplifier ye-optical isetyenziswa ngokuqhelekileyo kwiinkqubo zonxibelelwano ngendlela ye-pigtails, kunye ne-wavelength yokusebenza ejikeleze i-1300nm okanye i-1500nm, inikezela malunga ne-30dB yenzuzo.
II-SOA semiconductor optical amplifiersisixhobo sePN esidityanisiweyo esinobunzima besakhiwo sequla. I-bias yangaphandle yangaphandle ibuyisela inani lee-dielectric particles. Emva kokuba ukukhanya kwe-excitation yangaphandle kungene, i-radiation evuselelweyo yenziwa, ukuphumeza ukunyuswa kwezibonakaliso ze-optical. Zonke ezi nkqubo zintathu zogqithiso lwamandla zikhonaIamplifier ye-SOA. Ukwandiswa kwemiqondiso ye-optical kusekelwe kwi-stimulated emission. Ukufunxa okuvuselelweyo kunye neenkqubo ezikhuthazwayo zokukhutshwa zikhona ngaxeshanye. Ukuxutywa okukhuthazwayo kokukhanya kwempompo kungasetyenziselwa ukukhawuleza ukubuyiswa kwabathwali, kwaye ngelo xesha, ipompo yombane inokuthumela i-electron kwizinga eliphezulu lamandla (ibhendi yokuqhuba). Xa imitha yemitha ezenzekelayo yandisiwe, iya kwenza ingxolo yemitha eyandisiweyo ezenzekelayo. Iamplifier yokubona ye-SOA isekwe kwiitshiphusi zesemiconductor.
Iichips ze-Semiconductor zenziwe nge-semiconductors edibeneyo, njenge-GaAs / AlGaAs, i-InP / AlGaAs, i-InP / InGaAsP kunye ne-InP / InAlGaAs, njl. Ezi nazo zixhobo zokwenza i-lasemiconductor lasers. Uyilo lwe-waveguide lwe-SOA luyafana okanye lufana nelaser. Umahluko ulele ekubeni iilaser kufuneka zenze i-resonant cavity ejikeleze indawo yokuzuza ukuvelisa kunye nokugcina i-oscillation yesignali ye-optical. Isignali ye-optical iya kwandiswa amaxesha amaninzi kwi-cavity ngaphambi kokuba ikhutshwe. KwiIamplifier ye-SOA(into esiyixoxayo apha ilinganiselwe kwii-amplifiers ezijikelezayo ezisetyenziswa kwizicelo ezininzi), ukukhanya kufuneka kudlule kuphela kwindlela yokuzuza kube kanye, kwaye ukubonakaliswa ngasemva kuncinci. Isakhiwo se-SOA amplifier sineendawo ezintathu: Indawo ye-P, i-Area I (uluhlu olusebenzayo okanye i-node), kunye ne-Area N. Uluhlu olusebenzayo luhlala luqulunqwe yi-quantum Wells, enokuphucula ukuguqulwa kwe-photoelectric kunye nokunciphisa umda wangoku.
Umzobo we-1 I-laser ye-Fiber ene-SOA edibeneyo yokuvelisa i-pulses optical
Kusetyenziswa ugqithiselo lwetshaneli
Ii-SOA zihlala zingasetyenziswanga kuphela ekukhuliseni: zingaphinda zisetyenziswe kwintsimi yonxibelelwano lwe-fiber optical, izicelo ezisekelwe kwiinkqubo ezingabonakaliyo ezifana nokuzuza kwe-saturation okanye i-polarization ye-cross-phase, esebenzisa ukuhluka kwe-concentration carrier in SOA optical amplifier ukufumana i-indices ehlukeneyo ye-refractive. Ezi ziphumo zingasetyenziselwa ukuhanjiswa kwesiteshi (ukuguqulwa kwe-wavelength), ukuguqulwa kwefomathi yokumodareyitha, ukubuyiswa kwewashi, ukuhlaziywa komqondiso kunye nokuqatshelwa kwepateni, njl. kwiinkqubo zokuphindaphinda ulwahlulo lwamaza.
Ngokuqhubela phambili kweteknoloji yesekethe edibeneyo ye-optoelectronic kunye nokunciphisa iindleko zokuvelisa, imimandla yesicelo se-SOA semiconductor optical amplifier njenge-amplifiers eyisiseko, izixhobo ezisebenzayo kunye ne-subsystem components ziya kuqhubeka nokwandisa.
