Nzira yekushandisaamplifier ye optical ye semiconductor(SOA) ndeinotevera:
SOA semiconductor optical amplifier inoshandiswa zvakanyanya mumativi ese ehupenyu. Imwe yeindasitiri dzakakosha ndeyekutaurirana, iyo inokosheswa mukuita routing uye switching.amplifier yeSOA semiconductor opticalinoshandiswawo kuwedzera kana kuwedzera kuburitswa kwechiratidzo chekutaurirana kwefiber ye optical kure uye iamplifier yakakosha kwazvo ye optical.
Matanho ekutanga ekushandisa
Sarudza yakakodzeraSOA optical amplifier: Zvichienderana nemamiriro ezvinhu chaiwo ekushandisa uye zvinodiwa, sarudza SOA optical amplifier ine ma parameter akakodzera akadai se working wavelength, gain, saturated output power, uye noise figure. Semuenzaniso, muma optical communication systems, kana signal amplification ichizoitwa mu 1550nm band, SOA optical amplifier ine operating wavelength iri pedyo ne range iyi inofanira kusarudzwa.
Batanidza nzira ye optical: Batanidza magumo ekupinda eSOA semiconductor optical amplifier kune optical signal source inoda kuwedzerwa, uye batanidza magumo ekubudisa kune optical path inotevera kana optical device. Paunenge uchibatanidza, teerera kushanda kwe optical fiber uye edza kuderedza kurasikirwa kwe optical. Midziyo yakaita se fiber optic couplers uye optical isolators inogona kushandiswa kugadzirisa optical path connections.
Gadza bias current: Dzora gain yeSOA amplifier nekugadzirisa bias current yayo. Kazhinji, bias current yakakura, gain inowedzera, asi panguva imwe chete, zvinogona kutungamira mukuwedzera kweruzha uye shanduko musimba rekubuda rakazara. Kukosha kwakakodzera kwe bias current kunofanirwa kuwanikwa zvichibva pane zvinodiwa chaizvo uye ma parameter ekushanda kweSOA amplifier.
Kutarisa nekugadzirisa: Munguva yekushandisa, zvakakosha kutarisa simba remagetsi rinobuda, kuwedzera, ruzha nezvimwe zvikamu zveSOA munguva chaiyo. Zvichienderana nemigumisiro yekutarisa, bias current nezvimwe zvikamu zvinofanirwa kugadziriswa kuti zvive nechokwadi chekuti SOA semiconductor optical amplifier inoshanda zvakanaka uye ine hunhu hwechiratidzo.
Kushandiswa kwezvishandiso muzviitiko zvakasiyana-siyana
Sisitimu yekutaurirana yemaziso
Simba remagetsi: Chiratidzo chemagetsi chisati chatumirwa, SOA semiconductor optical amplifier inoiswa kumagumo ekutumira kuti iwedzere simba rechiratidzo chemagetsi uye kuwedzera daro rekutumira kwehurongwa. Semuenzaniso, mukutaurirana kwefiber yemagetsi kure kure, kuwedzera masaini emagetsi kuburikidza neSOA semiconductor optical amplifier kunogona kuderedza huwandu hwenzvimbo dzekutumira.
Amplifier yemutsara: Mumitsetse yekutumira masaini, SOA inoiswa panguva dzakati kuti itsive kurasikirwa kunokonzerwa nekuderedzwa kwefiber uye zvinobatanidza, zvichiita kuti zviratidzo zvemasaini zvionekwe zvakanaka panguva yekutumira masaini kure.
Preamplifier: Pamugumo wekugamuchira, SOA inoiswa pamberi peoptical receiver se preamplifier kuti iwedzere kunzwa kwemugamuchiri uye ivandudze kugona kwayo kuona zviratidzo zveoptical zvisina simba.
2. Sisitimu yekuona maziso
Mu demodulator ye fiber Bragg grating (FBG), SOA inowedzera chiratidzo che optical kuenda kuFBG, inodzora kutungamira kwechiratidzo che optical kuburikidza ne circulator, uye inonzwa shanduko mu wavelength kana nguva yechiratidzo che optical inokonzerwa nekusiyana kwekushisa kana kustrain. Mukuona chiedza uye kusiyanisa (LiDAR), narrowband SOA optical amplifier, kana ikashandiswa pamwe chete ne DFB lasers, inogona kupa simba guru rekuona kure.
3. Kushandurwa kwehurefu hwemafungu
Kushandurwa kweWavelength kunowanikwa nekushandisa zvinhu zvisiri zvemutsara zvakaita secross-gain modulation (XGM), cross-phase modulation (XPM), uye four-wave mixing (FWM) yeSOA optical amplifier. Semuenzaniso, muXGM, mwenje wekuona wave continuous wave detection beam uye mwenje wepombi wakasimba zvinopinzwa panguva imwe chete muSOA optical amplifier. Pombi inogadziriswa uye inoiswa kumwenje wekuona kuburikidza neXGM kuti iwane kushandurwa kwewavelength.
4. Jenareta yekurova kwemoyo (optical pulse generator)
Muzvinobatanidza zvekukurukurirana zveOTDM wavelength division multiplexing zvinomhanya zvakanyanya, ma lasers e fiber ring ane mode-locked ane SOA optical amplifier anoshandiswa kugadzira ma pulses anogadziriswa ne wavelength-rate repetition rate. Nekugadzirisa ma parameter akadai se bias current yeSOA amplifier uye modulation frequency yelaser, kubuda kwe optical pulses yema wavelengths akasiyana uye ma repetition frequency kunogona kuwanikwa.
5. Kudzoreredza wachi yemaziso
Muhurongwa hweOTDM, wachi inotorwa kubva kuzviratidzo zve optical zvinomhanya zvakanyanya kuburikidza ne phase-locked loops uye optical switches dzinoshandiswa zvichibva paSOA amplifier. OTDM data signal inosanganiswa neSOA ring mirror. Optical control pulse sequence inogadzirwa ne adjustable mode-locked laser inotyaira ring mirror. Output signal ye ring mirror inoonekwa ne photodiode. Frequency ye voltage-controlled oscillator (VCO) inovharwa pa fundamental frequency ye input data signal kuburikidza ne phase-locked loop, nokudaro zvichiita kuti optical clock recovery ibudirire.
