Mokhoa oa tšebeliso easemiconductor optical amplifier(SOA) e tjena:
SOA semiconductor optical amplifier e sebelisoa haholo mekhoeng eohle ea bophelo. E 'ngoe ea liindasteri tsa bohlokoa ka ho fetisisa ke tsa mehala, e nkoang e le ea bohlokoa tabeng ea ho tsamaisa le ho fetola.SOA semiconductor optical amplifiere boetse e sebelisetsoa ho ntlafatsa kapa ho holisa tlhahiso ea lets'oao la likhokahano tsa optical fiber tsa sebaka se selelele mme ke amplifier ea bohlokoa haholo.
Mehato ea mantlha ea tšebeliso
Khetha e loketsengSOA optical amplifier: Ho ipapisitsoe le maemo le litlhoko tse ikhethileng tsa ts'ebeliso, khetha SOA optical amplifier e nang le liparamente tse loketseng joalo ka ho sebetsa wavelength, gain, saturated output power, le lerata palo. Mohlala, lits'ebetsong tsa puisano tsa optical, haeba ho holisoa ha lets'oao ho tla etsoa sehlopheng sa 1550nm, SOA optical amplifier e nang le wavelength e sebetsang haufi le sebaka sena e hloka ho khethoa.
Kopanya tsela ea optical: Kopanya qetello ea ho kenya ea SOA semiconductor optical amplifier ho mohloli oa pontšo ea optical e lokelang ho ntlafatsoa, 'me u kopanye qetello ea tlhahiso ho tsela e latelang ea optical kapa sesebelisoa sa optical. Ha u kopanya, ela hloko bokhoni ba ho kopanya ha fiber ea optical mme u leke ho fokotsa tahlehelo ea optical. Lisebelisoa tse kang fiber optic couplers le optical isolator li ka sebelisoa ho ntlafatsa likhokahano tsa optical path.
Beha boemo ba hona joale: Laola phaello ea amplifier ea SOA ka ho fetola boemo ba eona ba hona joale. Ka kakaretso, ha ho na le leeme le lengata, phaello e phahame, empa ka nako e ts'oanang, e ka lebisa ho eketseha ha lerata le liphetoho ho matla a tsoang ho saturated. Boleng bo nepahetseng ba leeme la hajoale bo hloka ho fumanoa ho ipapisitsoe le litlhoko tsa 'nete le litekanyetso tsa ts'ebetso eaSOA amplifier.
Tlhokomelo le tokiso: Nakong ea ts'ebetso ea ts'ebeliso, hoa hlokahala ho beha leihlo matla a optical a hlahisoang, phaello, lerata le likarolo tse ling tsa SOA ka nako ea nnete. Ho ipapisitsoe le liphetho tsa ho beha leihlo, litekanyetso tsa bias tsa hajoale le tse ling li lokela ho lokisoa ho netefatsa ts'ebetso e tsitsitseng le boleng ba matšoao a SOA semiconductor optical amplifier.
Tšebeliso maemong a fapaneng a ts'ebeliso
Sistimi ea puisano ea optical
Matla a amplifier: Pele pontšo ea optical e fetisoa, SOA semiconductor optical amplifier e behoa qetellong ea phetisetso ho eketsa matla a pontšo ea optical le ho atolosa sebaka sa phetisetso ea tsamaiso. Ka mohlala, puisanong ea nako e telele ea fiber optical, ho matlafatsa matšoao a optical ka SOA semiconductor optical amplifier ho ka fokotsa palo ea liteishene tsa relay.
Linea amplifier: Meleng ea optical transmission, SOA e behoa ka linako tse itseng ho lefella tahlehelo e bakoang ke fiber attenuation le li-connectors, ho netefatsa boleng ba matšoao a optical nakong ea phetisetso ea nako e telele.
Preamplifier: Qetellong ea ho amohela, SOA e behoa ka pel'a mochine oa optical e le preamplifier ho matlafatsa kutloisiso ea moamoheli le ho ntlafatsa bokhoni ba eona ba ho lemoha bakeng sa matšoao a fokolang a optical.
2. Optical kutlo tsamaiso
Ka "fiber Bragg grating" (FBG) demodulator, SOA e matlafatsa lets'oao la optical ho FBG, e laola tataiso ea lets'oao la optical ka circulator, 'me e utloa liphetoho tsa wavelength kapa nako ea lets'oao la optical le bakoang ke mocheso kapa mefuta e fapaneng ea khatello. Ho lemoha leseli le ho fapana (LiDAR), narrowband SOA optical amplifier, ha e sebelisoa hammoho le DFB lasers, e ka fana ka matla a phahameng a tlhahiso bakeng sa ho lemoha nako e telele.
3. Phetoho ea Wavelength
Phetoho ea Wavelength e finyelloa ka ho sebelisa liphello tse se nang moeli tse kang cross-gain modulation (XGM), cross-phase modulation (XPM), le four-wave mixing (FWM) ea SOA optical amplifier. Ka mohlala, ho XGM, lebone le fokolang le sa khaotseng la ho lemoha maqhubu le lebone le matla la pompo li kenngoa ka nako e le 'ngoe ho SOA optical amplifier. Pompo e fetotsoe 'me e sebelisoa ho leseli la ho lemoha ka XGM ho finyella phetoho ea wavelength.
4. Optical pulse jenereithara
Lihokelong tse phahameng tsa lebelo la OTDM wavelength division multiplexing, li-lasers tsa fiber ring tse koetsoeng tse nang le SOA optical amplifier li sebelisoa ho hlahisa sekhahla se phahameng sa ho pheta-pheta maqhubu a matla a maqhubu. Ka ho fetola mekhoa e kang bias current ea SOA amplifier le modulation frequency ea laser, tlhahiso ea optical pulses ea wavelengths e fapaneng le maqhubu a ho pheta-pheta a ka finyelloa.
5. Optical oache ho hlaphoheloa
Sistimi ea OTDM, oache e khutlisoa ho tsoa lipontšong tsa optical tse lebelo le holimo ka li-loops tse notletsoeng ka mekhahlelo le li-switches tsa optical tse kentsoeng ts'ebetsong ho latela amplifier ea SOA. Letšoao la data la OTDM le kopantsoe le seipone sa lesale la SOA. Tatelano ea optical control pulse e hlahisoang ke laser e notletsoeng e notletsoeng e khanna seipone sa lesale. Letšoao la tlhahiso ea seipone sa lesale le bonoa ke photodiode. Khafetsa ea oscillator e laoloang ke motlakase (VCO) e notletsoe ka makhetlo a mangata a pontšo ea data ea ho kenya ka leqhubu le notletsoeng, ka tsela eo e finyella ho hlaphoheloa ha nako ea optical.
