Xhuma umzila we-optical: Xhuma isiphelo segalelo le-SOA semiconductor optical amplifier kumthombo wesignali optical ofuna ukukhuliswa, kwaye udibanise isiphelo somphumo kwindlela elandelayo okanye isixhobo sokukhanya. Xa udibanisa, nikela ingqalelo ekusebenzeni kokudibanisa kwe-fiber optical kwaye uzame ukunciphisa ilahleko ye-optical. Izixhobo ezifana ne-fiber optic couplers kunye ne-optical isolator zingasetyenziselwa ukwandisa uqhagamshelwano lwendlela yokubona.
Misela i-bias current: Lawula inzuzo ye-SOA amplifier ngokulungisa i-bias current current. Ngokuqhelekileyo, i-bias yangoku inkulu, inzuzo ephezulu, kodwa kwangaxeshanye, inokukhokelela ekwandeni kwengxolo kunye notshintsho kumandla aphumayo. Ixabiso langoku lokuthambekela elifanelekileyo kufuneka lifunyanwe ngokusekelwe kwiimfuno zokwenyani kunye neeparamitha zokusebenza zeIamplifier ye-SOA.
Ukubeka iliso kunye nokulungelelaniswa: Ngexesha lenkqubo yokusetyenziswa, kuyimfuneko ukubeka iliso kwi-output optical power, inzuzo, ingxolo kunye nezinye iiparitha ze-SOA ngexesha langempela. Ngokusekelwe kwiziphumo zokubeka iliso, i-bias current kunye nezinye iiparameters kufuneka zilungiswe ukuze kuqinisekiswe ukusebenza okuzinzile kunye nomgangatho wesignali we-SOA semiconductor optical amplifier.
Ukusetyenziswa kwiimeko ezahlukeneyo zokusetyenziswa
Inkqubo yonxibelelwano yamehlo
I-amplifier yamandla: Ngaphambi kokuba isignali ye-optical idluliselwe, i-SOA semiconductor optical amplifier ibekwe ekupheleni kokudlulisa ukunyusa amandla omqondiso we-optical kunye nokwandisa umgama wokuhanjiswa kwenkqubo. Ngokomzekelo, kumgama omde wonxibelelwano lwefiber optical, ukwandisa izibonakaliso ze-optical ngokusebenzisa i-SOA semiconductor optical amplifier kunokunciphisa inani lezikhululo zokubuyisela.
I-amplifier yomgca: Kwimigca yokuhambisa i-optical transmission, i-SOA ibekwe ngamaxesha athile ukuhlawula ilahleko ebangelwa yi-fiber attenuation kunye nezixhumi, ukuqinisekisa umgangatho weempawu ze-optical ngexesha lokuhanjiswa kwexesha elide.
I-Preamplifier: Ekupheleni kokufumana, i-SOA ibekwe phambi kwe-receiver optical njenge-preamplifier yokuphucula ukuvakalelwa kommkeli kunye nokuphucula ukukwazi kwayo ukufumanisa iimpawu ze-optical ezibuthathaka.
2. Inkqubo yokubona ngamehlo
Kwi-fiber Bragg grating (FBG) i-demodulator, i-SOA iphakamisa isignali ye-optical kwi-FBG, ilawula isalathiso somqondiso we-optical ngokusebenzisa i-circulator, kwaye ivakalelwa utshintsho kwi-wavelength okanye ixesha lomqondiso we-optical obangelwa ubushushu okanye ukuhluka koxinzelelo. Ekubonweni kokukhanya kunye ne-range (LiDAR), i-narrowband ye-SOA ye-optical amplifier, xa isetyenziswe ngokubambisana ne-DFB lasers, inokubonelela ngamandla aphezulu okuvelisa ukubonwa komgama omde.
3. Ukuguqulwa kweWavelength
Ukuguqulwa kwe-Wavelength kufezekiswa ngokusebenzisa imiphumo engabonakaliyo efana ne-cross-gain modulation (XGM), i-modulation ye-cross-phase modulation (XPM), kunye ne-four-wave mixing (FWM) ye-SOA optical amplifier. Ngokomzekelo, kwi-XGM, i-wave wave ebuthathaka eqhubekayo yokubona ukukhanya kunye ne-beam yokukhanya yempompo eyomeleleyo ifakwe ngaxeshanye kwi-SOA optical amplifier. Ipompo iguqulwe kwaye isetyenziswe ekukhanyeni ukukhanya nge-XGM ukufezekisa ukuguqulwa kwe-wavelength.
4. I-Optical pulse generator
Kwinqanaba eliphezulu le-OTDM icandelo le-wavelength ye-multiplexing yonxibelelwano lwamakhonkco onxibelelwano, i-mode-locked i-fiber ring lasers equlethe i-SOA optical amplifier isetyenziselwa ukuvelisa izinga eliphezulu lokuphindaphinda i-wavelength-tunable pulses. Ngokulungelelanisa iiparitha ezifana ne-bias current ye-SOA amplifier kunye ne-modulation frequency ye-laser, ukuphuma kwee-pulses optical of wavelengths ezahlukeneyo kunye nokuphindaphinda ukuphindaphinda kunokufezekiswa.
5. Ukubuyiswa kwewotshi ye-Optical
Kwinkqubo ye-OTDM, iwashi ibuyiswa kwiimpawu ze-optical ze-speed-speed ngokusebenzisa i-loops evaliweyo yesigaba kunye nokutshintsha okubonakalayo okuphunyeziweyo ngokusekelwe kwi-SOA amplifier. Isiginali yedatha ye-OTDM idityaniswe kwisibuko se-SOA ring. I-optical control pulse sequence eyenziwe yi-laser mode adjustable-locked laser iqhuba isibuko sendandatho. Isibonakaliso sokuphuma kwesibuko sendandatho sibonwa yi-photodiode. Ubuninzi be-oscillator elawulwa yi-voltage (VCO) itshixiwe kwi-frequency esisiseko yesignali yedatha yegalelo ngokusebenzisa i-loop-locked loop, ngaloo ndlela iphumelele ukubuyiswa kwewashi.
