Indlela yokusebenzisa i-amplifier ye-semiconductor optical

Indlela yokusebenzisai-amplifier ye-semiconductor optical(i-SOA) imi kanje:

I-amplifier ye-optical ye-SOA semiconductor isetshenziswa kabanzi kuzo zonke izindlela zokuphila. Enye yezimboni ezibaluleke kakhulu ukuxhumana ngezingcingo, okubaluleke kakhulu ekuqondiseni nasekushintsheni.I-amplifier ye-optical ye-semiconductor ye-SOAisetshenziselwa futhi ukuthuthukisa noma ukukhulisa umphumela wesiginali wokuxhumana kwefayibha ye-optical ebangeni elide futhi iyi-amplifier ye-optical ebaluleke kakhulu.

Izinyathelo eziyisisekelo zokusebenzisa

Khetha okufaneleI-amplifier ye-SOA optical: Ngokusekelwe ezimweni ezithile zohlelo lokusebenza kanye nezidingo, khetha i-SOA optical amplifier enemingcele efanelekile efana nobude besikhathi obusebenzayo, inzuzo, amandla okukhipha agcwele, kanye nobukhulu bomsindo. Isibonelo, ezinhlelweni zokuxhumana ze-optical, uma ukukhuliswa kwesiginali kuzokwenziwa ebhendini le-1550nm, i-SOA optical amplifier enobude besikhathi obusebenzayo obuseduze nalolu hlu idinga ukukhethwa.

Xhuma indlela yokukhanya: Xhuma ingxenye yokufaka ye-SOA semiconductor optical amplifier emthonjeni wesignali yokukhanya odinga ukukhuliswa, bese uxhuma ingxenye yokuphuma endleleni elandelayo yokukhanya noma idivayisi yokukhanya. Uma uxhuma, naka ukusebenza kahle kokuxhuma kwe-fiber yokukhanya bese uzama ukunciphisa ukulahleka kokukhanya. Amadivayisi afana nama-couplers e-fiber optic kanye nama-isolators okukhanya angasetshenziswa ukwenza ngcono ukuxhumana kwendlela yokukhanya.

Setha ugesi we-bias: Lawula ugesi we-amplifier ye-SOA ngokulungisa ugesi wayo we-bias. Ngokuvamile, uma ugesi we-bias umkhulu, ugesi we-bias uyanda, kodwa ngesikhathi esifanayo, kungaholela ekwandeni komsindo kanye nezinguquko emandleni okukhipha agcwele. Inani lamanje le-bias elifanele lidinga ukutholakala ngokusekelwe ezidingweni zangempela kanye nemingcele yokusebenza ye-Isikhulisi se-SOA.

Ukuqapha nokulungisa: Ngesikhathi senqubo yokusebenzisa, kuyadingeka ukuqapha amandla okukhanya okukhiphayo, inzuzo, umsindo kanye nezinye izinhlaka ze-SOA ngesikhathi sangempela. Ngokusekelwe emiphumeleni yokuqapha, i-bias current kanye nezinye izinhlaka kufanele zilungiswe ukuqinisekisa ukusebenza okuzinzile kanye nekhwalithi yesignali ye-SOA semiconductor optical amplifier.

Ukusetshenziswa ezimweni ezahlukene zohlelo lokusebenza

Uhlelo lokuxhumana olubonakalayo

I-Power amplifier: Ngaphambi kokuba isignali ye-optical idluliselwe, i-SOA semiconductor optical amplifier ibekwa ekugcineni kokudlulisa ukuze kwandiswe amandla esignali ye-optical futhi kwandiswe ibanga lokudlulisa lesistimu. Isibonelo, ekuxhumaneni kwe-optical fiber ekude, ukukhulisa amasignali e-optical nge-SOA semiconductor optical amplifier kunganciphisa inani leziteshi zokudlulisela.

I-Line amplifier: Emigqeni yokudlulisa ukukhanya, i-SOA ibekwa ngezikhathi ezithile ukuze ikhokhele ukulahlekelwa okubangelwa ukuncishiswa kwefayibha kanye nezixhumi, okuqinisekisa ikhwalithi yezimpawu zokukhanya ngesikhathi sokudlulisa ibanga elide.

I-Preamplifier: Ekupheleni kokwamukela, i-SOA ibekwa phambi kwe-optical receiver njenge-preamplifier ukuze kuthuthukiswe ukuzwela kwe-receiver futhi kuthuthukiswe ikhono layo lokuthola izimpawu zokukhanya ezibuthakathaka.

2. Uhlelo lokuzwa okubonakalayo

Ku-demodulator ye-fiber Bragg grating (FBG), i-SOA ikhulisa isignali ye-optical ku-FBG, ilawula indlela yesignali ye-optical nge-circulator, futhi izwa izinguquko ku-wavelength noma isikhathi sesignali ye-optical esibangelwa ukushintsha kwezinga lokushisa noma ukucindezeleka. Ekutholeni nasekulinganiseni ukukhanya (i-LiDAR), i-narrowband SOA optical amplifier, uma isetshenziswa kanye nama-laser e-DFB, inganikeza amandla aphezulu okukhipha ukuze kutholakale ibanga elide.

3. Ukuguqulwa kobude begagasi

Ukuguqulwa kwe-Wavelength kufezwa ngokusebenzisa imiphumela engeyona eye-linear efana ne-cross-gain modulation (XGM), i-cross-phase modulation (XPM), kanye ne-four-wave mixing (FWM) ye-SOA optical amplifier. Isibonelo, ku-XGM, i-weak continuous wave detection light beam kanye ne-strong pump light beam kufakwa ngesikhathi esisodwa ku-SOA optical amplifier. I-pump iyalungiswa futhi isetshenziswe ekukhanyeni kokuthola nge-XGM ukuze kufezwe ukuguqulwa kwe-wavelength.

4. Ijeneretha yokushaya kwenhliziyo ebonakalayo

Ezixhumanweni zokuxhumana ze-OTDM wavelength division multiplexing ezisheshayo, ama-laser e-fiber ring avaliwe ngemodi aqukethe i-SOA optical amplifier asetshenziselwa ukukhiqiza ama-pulse aguquguqukayo we-wavelength ngesivinini esiphezulu. Ngokulungisa amapharamitha afana ne-bias current ye-SOA amplifier kanye ne-modulation frequency ye-laser, umphumela wama-optical pulses wama-wavelength ahlukene kanye nama-repeat frequency ungafinyelelwa.

5. Ukuvuselelwa kwewashi le-Optical

Kuhlelo lwe-OTDM, iwashi litholakala kumasignali optical asheshayo ngokusebenzisa ama-loops akhiyiwe ngesigaba kanye nama-switch optical asetshenziswa ngokusekelwe ku-amplifier ye-SOA. Isignali yedatha ye-OTDM ixhunywe nesibuko sendandatho ye-SOA. Uchungechunge lokulawula i-optical olukhiqizwa yi-laser ekhiyiwe ngemodi elungisekayo lushayela isibuko sendandatho. Isignali yokuphuma kwesibuko sendandatho itholwa yi-photodiode. Imvamisa ye-oscillator elawulwa yi-voltage (VCO) ikhiyiwe ngemvamisa eyisisekelo yesignali yedatha yokufaka nge-loop ekhiyiwe ngesigaba, ngaleyo ndlela kufezwe ukubuyiselwa kwewashi le-optical.
