Optical amplifiernhevedzano: Nhanganyaya kuSemiconductor Optical Amplifier
Semiconductor optical amplifier(SOA) i optical amplifier yakavakirwa pa semiconductor gain media. Zvakafanana ne fiber coupled semiconductor laser tube, ine end mirror yakatsiviwa ne anti reflective film; Tilted waveguides inogona kushandiswa kuderedza end reflectivity. Chiedza chesignal chinowanzo tumirwa kuburikidza ne semiconductor single-mode waveguide, ine lateral dimension ye 1-2 μ m uye kureba kweinenge 0.5-2mm. Waveguide mode inowirirana zvakanyanya nenzvimbo inoshanda (amplification), iyo inopombwa ne current. Injecting current inogadzira carrier density yakati mu conduction band, zvichibvumira optical transitions kubva ku conduction band kuenda ku valence band. Maximum gain inoitika pa photon energy pamusoro pe bandgap energy.
Nheyo yekushanda kwe semiconductor optical amplifier
Ma amplifiers e optical e semiconductor (SOA) inowedzera zviratidzo zvechiedza kuburikidza nekuburitswa kwesimba, uye mashandiro azvo akafanana neema semiconductor lasers.SOA optical amplifierinongova semiconductor laser isina mhinduro, uye chinangwa chayo ndechekuwana optical gain nekudzosera shure huwandu hwezvikamu kana semiconductor optical amplifier ichipombwa ne optically kana electrically.
Mhando dzeSOA Semiconductor optical amplifier
Zvichienderana nebasa rinoitwa neSOA mumasisitimu evatengi, anogona kukamurwa kuita zvikamu zvina: serial, booster, switching SOA, uye preamplifier.
1. Kupinza zvakananga: kuwedzera kwakanyanya, Psat iri pakati nepakati; NF yakaderera uye PDG yakaderera, inowanzobatanidzwa ne polarisation yakazvimiririra SOA·
2. Enhancer: Psat Yakakwira, kuwedzera kwakaderera, kazhinji kunoenderana nekupatsanurwa;
3. Chinja: chiyero chepamusoro chekutsakatika kwemhuka uye nguva yekukwira/kudonha nekukurumidza;
4. Pre amplifier: yakakodzera mafambiro marefu ekutumirwa, NF yakaderera, uye kuwedzera kwekuwedzera.
Mabhenefiti eSOA Semiconductor optical amplifier
Kuwana kwechiedza kunopiwa neSOA mukati mebandwidth hakuenderane nehukuru hwewavelength yechiratidzo chechiedza chechiitiko.
Isa simba remagetsi sechiratidzo chepombi yakawedzerwa, pane kupomba kwemagetsi.
Nekuda kwehukuru hwayo hudiki, SOA inogona kubatanidzwa nemidziyo yakawanda ye photonic ye waveguide pane imwe substrate yakarongwa.
4. Vanoshandisa tekinoroji imwecheteyo ne diode lasers.
SOA inogona kushanda mumabhendi ekukurukurirana e1300 nm uye 1550 nm, ine bandwidth yakafara (kusvika ku100 nm).
6. Zvinogona kugadziriswa uye kubatanidzwa kuti zvishande sema preamplifier kumagumo e optical receiver.
SOA inogona kushandiswa senzira iri nyore yekuongorora mashandisirwo emagetsi muWDM optical networks.
Miganhu yeSOA Semiconductor optical amplifier
SOA inogona kupa simba remagetsi rinobuda rinosvika makumi emamiriyoni (mW), izvo zvinowanzo kukwana kushanda kwechiteshi chimwe chete mu fiber optic communication links. Zvisinei, masisitimu eWDM angada simba rinosvika mW dzakawanda pachiteshi chimwe nechimwe.
2. Nekuda kwekubatana kwemafiber e optical anopinda nekubuda mumachipisi akabatanidzwa eSOA anowanzo kukonzera kurasikirwa kwechiratidzo, SOA inofanira kupa kuwedzera kwekuwedzera kwe optical kuderedza kukanganisa kwekurasikirwa uku pane zvinopinda/zvinobuda munzvimbo inoshanda.
SOA inonzwa zvakanyanya kana zviratidzo zve optical zvichikwira.
4. Dzinogadzira ruzha rwakanyanya mumagetsi anoshanda kupfuura fiber amplifiers.
Kana nzira dzakawanda dze optical dzikawedzerwa sezvinodiwa muWDM applications, SOA inokonzera kutaurirana kwakasimba.
