Amanyathelo okusebenzisa asisiseko
Khetha efanelekileyoIsikhulisi se-SOA optical: Ngokusekelwe kwiimeko ezithile zesicelo kunye neemfuno, khetha i-SOA optical amplifier eneeparameter ezifanelekileyo ezifana nobude bexesha obusebenzayo, i-gain, amandla okukhupha agcweleyo, kunye nomfanekiso wengxolo. Umzekelo, kwiinkqubo zonxibelelwano lwe-optical, ukuba ukwandiswa kwesignali kuza kwenziwa kwibhendi ye-1550nm, i-SOA optical amplifier ene-operating wavelength ekufutshane nolu luhlu kufuneka ikhethwe.
Qhagamshela indlela yokukhanya: Qhagamshela isiphelo sokufaka se-SOA semiconductor optical amplifier kumthombo wesignali yokukhanya ofuna ukwandiswa, kwaye uqhagamshele isiphelo sokukhanya kwindlela elandelayo yokukhanya okanye isixhobo sokukhanya. Xa uqhagamshela, qwalasela ukusebenza kakuhle kokudibanisa kwefayibha yokukhanya kwaye uzame ukunciphisa ukulahleka kokukhanya. Izixhobo ezifana nee-fiber optic couplers kunye nee-optical isolators zingasetyenziselwa ukuphucula uqhagamshelo lwendlela yokukhanya.
Seta i-bias current: Lawula i-gain ye-amplifier ye-SOA ngokulungelelanisa i-bias current yayo. Ngokubanzi, i-bias current inkulu, i-gain iphezulu, kodwa kwangaxeshanye, inokukhokelela ekwandeni kwengxolo kunye notshintsho kumandla okukhupha agcweleyo. Ixabiso elifanelekileyo le-bias current kufuneka lifunyanwe ngokusekelwe kwiimfuno zokwenyani kunye neeparamitha zokusebenza zeIsikhulisi se-SOA.
Ukubeka iliso kunye nohlengahlengiso: Ngexesha lenkqubo yokusetyenziswa, kuyimfuneko ukubeka iliso kumandla okukhanya okuphumayo, inzuzo, ingxolo kunye nezinye iiparameter ze-SOA ngexesha langempela. Ngokusekelwe kwiziphumo zokubeka iliso, i-bias current kunye nezinye iiparameter kufuneka zilungiswe ukuqinisekisa ukusebenza okuzinzileyo kunye nomgangatho wesignali ye-SOA semiconductor optical amplifier.
Ukusetyenziswa kwiimeko ezahlukeneyo zokusetyenziswa
Inkqubo yonxibelelwano lwe-Optical
I-Power amplifier: Ngaphambi kokuba i-optical signal idluliselwe, i-SOA semiconductor optical amplifier ibekwa kwisiphelo sokudlulisa ukuze kwandiswe amandla e-optical signal kwaye kwandiswe umgama wokudlulisa wenkqubo. Umzekelo, kunxibelelwano lwe-optical fiber olude, ukukhulisa i-optical signals nge-SOA semiconductor optical amplifier kunokunciphisa inani lezikhululo zokudlulisela.
I-Line amplifier: Kwimigca yokudlulisa ukukhanya, i-SOA ibekwa ngamaxesha athile ukuze ihlawulele ilahleko ebangelwa kukuncipha kwefayibha kunye nezihlanganisi, ukuqinisekisa umgangatho wemiqondiso yokudlulisa ukukhanya ngexesha lokudlulisa umgama omde.
I-Preamplifier: Kwisiphelo sokwamkela, i-SOA ibekwa phambi kwe-optical receiver njenge-preamplifier ukuphucula uvakalelo lommkeli kunye nokuphucula amandla akhe okubona imiqondiso ye-optical ebuthathaka.
2. Inkqubo yokuva ukukhanya
Kwi-demodulator ye-fiber Bragg grating (FBG), i-SOA inyusa isignali ye-optical ukuya kwi-FBG, ilawula indlela yesignali ye-optical nge-circulator, kwaye iva utshintsho kubude be-wavelength okanye ixesha lesignali ye-optical ebangelwa kukutshintsha kobushushu okanye ukuxinana. Kwi-light detection and ranging (LiDAR), i-narrowband SOA optical amplifier, xa isetyenziswa kunye ne-DFB lasers, inokubonelela ngamandla aphezulu okukhupha umgama omde.
3. Ukuguqulwa kobude bamaza
Ukuguqulwa kwe-Wavelength kufezekiswa ngokusebenzisa iziphumo ezingezizo ezilandelelanayo ezifana ne-cross-gain modulation (XGM), i-cross-phase modulation (XPM), kunye ne-four-wave mixing (FWM) ye-SOA optical amplifier. Umzekelo, kwi-XGM, i-weak continuous wave detection light beam kunye ne-strong pump light beam zifakwa ngaxeshanye kwi-SOA optical amplifier. I-pump iyalungiswa kwaye isetyenziswe kwisibane sokufumanisa nge-XGM ukufezekisa ukuguqulwa kwe-wavelength.
4. Ijenereyitha ye-optical pulse
Kwiikhonkco zonxibelelwano ze-OTDM wavelength division multiplexing communication, ii-laser ze-fiber ring ezine-mode-locked ezine-SOA optical amplifier zisetyenziselwa ukuvelisa ii-pulses ezinokuhlengahlengiswa ngesantya esiphezulu se-wavelength. Ngokulungisa iiparameter ezifana ne-bias current ye-SOA amplifier kunye ne-modulation frequency ye-laser, imveliso yee-optical pulses zama-wavelength ahlukeneyo kunye nee-repetition frequency zinokufezekiswa.
5. Ukubuyiselwa kwewotshi ebonakalayo
Kwinkqubo ye-OTDM, iwotshi ifunyanwa kwimiqondiso ye-optical ekhawulezayo ngokusebenzisa ii-loops ezitshixiweyo zesigaba kunye neeswitshi ze-optical ezisetyenziswa ngokusekelwe kwi-amplifier ye-SOA. Isignali yedatha ye-OTDM idityaniswe nesibuko sendandatho ye-SOA. Ulandelelwano lwe-optical control pulse oluveliswa yi-laser ehlengahlengiswayo yemode luqhuba isibuko sendandatho. Isignali yokuphuma kwesibuko sendandatho ibonwa yi-photodiode. I-frequency ye-oscillator elawulwa yi-voltage (VCO) itshixiwe kwi-frequency esisiseko yesignali yedatha yokufaka nge-phase-locked loop, ngaloo ndlela ifezekisa ukubuyiswa kwewotshi ye-optical.
