Nzira yekushandisa yesemiconductor optical amplifier(SOA) ndeiyi inotevera:
SOA semiconductor optical amplifier inoshandiswa zvakanyanya mumatanho ese ehupenyu. Imwe yemaindasitiri akanyanya kukosha ndeyekufonera, iyo inokosheswa mukufambisa uye kuchinja.SOA semiconductor Optical amplifierinoshandiswawo kukwidziridza kana kukwidziridza kuburitsa kwechiratidzo chekureba-kure optical fiber kutaurirana uye yakakosha zvakanyanya optical amplifier.
Matanho ekutanga ekushandisa
Sarudza zvakakodzeraSOA Optical amplifier: Kubva pane chaiwo mamiriro ekushandisa uye zvinodiwa, sarudza SOA Optical amplifier ine yakakodzera paramita sekushanda wavelength, kuwana, saturated kubuda simba, uye ruzha nhamba. Semuyenzaniso, mune optical communication masisitimu, kana chiratidzo chekusimudzira chichizoitwa mubhendi re1550nm, SOA optical amplifier ine inoshanda wavelength padyo nerenji iyi inoda kusarudzwa.
Batanidza nzira yekuona: Batanidza iyo yekupedzisira yekupinza yeSOA semiconductor optical amplifier kune optical chiratidzo sosi inoda kukwidziridzwa, uye batanidza iyo inobuda yekupedzisira kune inotevera nzira yekuona kana optical mudziyo. Paunenge uchibatanidza, teerera kuhutano hwekubatanidza kwefiber optical uye edza kuderedza kurasikirwa kwemaziso. Zvishandiso zvakaita sefiber optic couplers uye optical isolators zvinogona kushandiswa kukwenenzvera nzira dzekubatanidza.
Seta iyo bias ikozvino: Dzora kuwana kweSOA amplifier nekugadzirisa iyo bias ikozvino. Kazhinji kutaura, iyo yakakura yekusarura ikozvino, iyo inowedzera pfuma, asi panguva imwe chete, inogona kutungamira mukuwedzera kweruzha uye shanduko mune yakazara saturated goho simba. Iko kurerekera kwakakodzera kwazvino kukosha kunoda kuwanikwa zvichibva pane izvo chaizvo zvinodiwa uye maitiro ekuita maparamita eSOA amplifier.
Kuongorora uye kugadzirisa: Munguva yekushandiswa kwemaitiro, zvinodikanwa kuti utarise inobuda optical simba, kuwana, ruzha uye mamwe ma parameter eSOA munguva chaiyo. Zvichienderana nemhedzisiro yekutarisa, iyo bias ikozvino uye mamwe ma paramita anofanirwa kugadziridzwa kuti ave nechokwadi chekuita kwakagadzikana uye chiratidzo chemhando yeSOA semiconductor optical amplifier.
Kushandiswa mumamiriro akasiyana ekushandisa
Optical communication system
Simba amplifier: Pamberi pechiratidzo chemaziso chisati chaendeswa, iyo SOA semiconductor optical amplifier inoiswa pamagumo ekutumira kuti iwedzere simba rechiratidzo chemaziso uye kuwedzera kureba kwekufambisa kwegadziriro. Semuyenzaniso, mune refu-kure optical fiber kutaurirana, kukwidziridza masaini masaini kuburikidza neSOA semiconductor optical amplifier inogona kuderedza nhamba yezviteshi zverelay.
Line amplifier: Mumitsara yekufambisa maziso, SOA inoiswa pane dzimwe nguva kubhadhara kurasikirwa kunokonzerwa nefiber attenuation uye zvibatanidza, kuve nechokwadi chehutano hwezviratidzo zvemaziso panguva yekufambisa kure kure.
Preamplifier: Pakupera kwekugamuchira, iyo SOA inoiswa pamberi peiyo optical receiver se preamplifier kuti iwedzere kunzwisiswa kweanogamuchira uye kuvandudza kugona kwayo kwekuona kune isina simba masaini masaini.
2. Optical sensing system
Mune fiber Bragg grating (FBG) demodulator, SOA inokwidziridza chiratidzo chemaziso kuFBG, inodzora gwara rechiratidzo chemaziso kuburikidza neinotenderera, uye inonzwa shanduko muwavelength kana nguva yechiratidzo chemaziso chinokonzerwa nekupisa kana kushushikana kwakasiyana. Mukuona kwechiedza uye kubva (LiDAR), narrowband SOA optical amplifier, kana yakashandiswa pamwe chete neDFB lasers, inogona kupa yakakwira kubuda simba rekuona kure-kure.
3. Wavelength kutendeuka
Wavelength shanduko inowanikwa nekushandisa zvisina mutsara mhedzisiro senge cross-gain modulation (XGM), cross-phase modulation (XPM), uye ina-wave mixing (FWM) yeSOA optical amplifier. Semuyenzaniso, muXGM, isina simba inoenderera mberi yekuona mwenje wemwenje uye yakasimba pombi mwenje wemwenje inoiswa panguva imwe chete muSOA optical amplifier. Iyo pombi inogadziriswa uye inoshandiswa kune mwenje wekuona kuburikidza neXGM kuti iwane wavelength kutendeuka.
4. Optical pulse jenareta
Mune yakakwirira-yekukurumidza OTDM wavelength division multiplexing communication links, mode-yakiyiwa fiber mhete lasers ine SOA optical amplifier inoshandiswa kugadzira yakakwirira yekudzokorora mwero wavelength-tunable pulses. Nekugadzirisa maparamendi akadai seyazvino bias yeSOA amplifier uye modulation frequency ye laser, kubuda kwemaoptical pulses emhando dzakasiyana dzewavelengths uye kudzokorora mafambiro anogona kuwanikwa.
5. Optical wachi kupora
Muiyo OTDM system, wachi inodzoserwa kubva kune yakakwirira-kumhanya masaini masaini kuburikidza nechikamu-yakakiyiwa zvishwe uye optical switch inoiswa yakavakirwa paSOA amplifier. Iyo OTDM data siginecha yakabatanidzwa kune iyo SOA mhete girazi. Iyo optical control pulse sequence inogadzirwa neinogadziriswa modhi-yakiyiwa laser inotyaira girazi remhete. Chiratidzo chekubuda chegirazi remhete chinoonekwa nephotodiode. Iyo frequency yevoltage-inodzorwa oscillator (VCO) yakavharwa paiyo yakakosha frequency yeiyo yekuisa data chiratidzo kuburikidza nechikamu-yakakiyiwa loop, nekudaro kuwana yekuona wachi kupora.
