Optical amplifiernhepfenyuro: Nhanganyaya kune Semiconductor Optical Amplifier
Semiconductor optical amplifier(SOA) ndeye optical amplifier yakavakirwa pane semiconductor kuwana midhiya. Zvakanyanya kufanana nefiber yakasanganiswa semiconductor laser chubhu, ine girazi rekupedzisira rakatsiviwa ne anti reflective film; Tilted waveguides inogona kushandiswa kuwedzera kudzikisa iyo yekupedzisira reflectivity. Chiedza chechiratidzo chinowanzoendeswa kuburikidza ne semiconductor single-mode waveguide, ine lateral dimension ye 1-2 μ m uye urefu hunosvika 0.5-2mm. Iyo waveguide mode inopindirana zvakanyanya neiyo inoshanda (amplification) dunhu, iyo inopombwa neyazvino. Jekiseni ikozvino inoburitsa imwe density yekutakura mubhendi yekuitisa, ichibvumira shanduko yemaziso kubva kubhendi yekuitisa kuenda kubhendi yevalence. Kuwana kwakanyanya kunoitika paphoton simba zvishoma pamusoro peiyo bandgap simba.
Kushanda musimboti we semiconductor optical amplifier
Semiconductor Optical amplifiers (SOA) kusimudzira masaini emwenje echiitiko kuburikidza nekusimudzirwa kuburitsa, uye maitiro avo akafanana neayo semiconductor lasers.SOA Optical amplifieringori semiconductor laser isina mhinduro, uye musimboti wayo ndeyekuwana kuwana kwekuona nekudzoreredza huwandu hwezvimedu kana semiconductor optical amplifier iri optical kana magetsi kupomba.
Mhando dzeSOA Semiconductor Optical amplifier
Zvinoenderana nebasa rakaitwa neSOA mune zvevatengi masisitimu, vanogona kukamurwa kuita zvikamu zvina: serial, booster, switching SOA, uye preamplifier.
1. Kupinza kwakananga: kuwana kwepamusoro, Psat ine mwero; Yakaderera NF uye yakaderera PDG, inowanzobatanidzwa nepolarization yakazvimirira SOA·
2. Enhancer: Higher Psat, yakaderera kuwana, kazhinji zvinoenderana polarization;
3. Shandura: yakakwira yekutsakatika ratio uye nekukurumidza kusimuka / kudonha nguva;
4. Pre amplifier: inokodzera kureba kwekufambisa madaro, yakaderera NF, uye yakakwirira kuwana.
Zvakanakira zveSOA Semiconductor Optical amplifier
Kuwana kwemaziso kunopiwa neSOA mukati me bandwidth inenge yakasununguka kune wavelength yechiitiko chechiratidzo chemaziso.
Jekiseni ikozvino sechiratidzo chepombi chakasimudzirwa, pane kupomba kwemaziso.
Nekuda kwehukuru hwayo compact, SOA inogona kusanganiswa neakawanda waveguide photonic zvishandiso pane imwechete planar substrate.
4. Vanoshandisa teknolojia imwechete se diode lasers.
SOA inogona kushanda mumabhendi ekutaurirana e1300 nm uye 1550 nm, ane bandwidth yakafara (kusvika ku100 nm).
6. Inogona kugadziriswa uye yakabatanidzwa kuti ishande sepreamplifiers pamagumo ekugamuchira optical.
SOA inogona kushandiswa seyakareruka logic gedhi muWDM optical network.
Kukanganisa kweSOA Semiconductor Optical amplifier
SOA inogona kupa inobuda magetsi emagetsi anosvika makumi emamilliwatts (mW), ayo anowanzo kukwana kune imwechete chiteshi mashandiro mufiber optic communication links. Nekudaro, masisitimu eWDM angangoda kusvika akati wandei mW emagetsi pachiteshi.
2. Pamusana pekubatana kwekupinza optical fibers mukati uye kunze kweSOA yakasanganiswa chips kazhinji inokonzera kurasikirwa kwechiratidzo, SOA inofanira kupa mamwe maonero ekuona kuti kuderedze kukanganisa kwekurasikirwa uku pane zvinyorwa / zvinyorwa zvenharaunda inoshanda.
SOA inonzwa zvakanyanya kune polarization yekuisa masaini masaini.
4. Dzinoburitsa mazinga akakwirira eruzha mune inoshingaira midhiya kupfuura fiber amplifiers.
Kana akawanda optical chiteshi akakwidziridzwa sezvinodiwa muWDM application, SOA inokonzeresa yakanyanya crosstalk.
