Fa'aola matafaasologa: Folasaga i Semiconductor Optical Amplifier
Semiconductor optical amplifier(SOA) ose fa'apipi'i fa'apipi'i fa'avae i luga ole fa'asalalauga maua semiconductor. E matua pei lava o se fa'alava fa'apipi'i fa'apa'u leisa semiconductor, fa'atasi ai ma le fa'ata pito e sui i se ata fa'afoma'i fa'aanti; E mafai ona fa'aogaina ta'iala fa'afefeteina e fa'aitiitia atili ai le fa'afoliga fa'ai'uga. Fa'ailoga moli e masani lava ona tu'uina atu e ala i se semiconductor tasi-mode waveguide, fa'atasi ai ma le lautele o le 1-2 μm ma le umi e tusa ma le 0.5-2mm. O le ala ta'avale e matua'i fa'alava ma le vaega galue (fa'aliga), lea e pamu i le taimi nei. O le tui o le taimi nei e maua ai se vaʻa faʻapitoa i totonu o le faʻaupuga faʻaulu, e mafai ai ona faʻaogaina suiga mai le paʻu faʻaulu i le valence band. Ole maualuga maualuga e maua ile malosi ole photon i luga a'e laititi ole malosi ole bandgap.
Fa'atonuga galue o le fa'apipi'i fa'apitoa semiconductor
Semiconductor amplifiers opitika(SOA) faʻateleina faʻamatalaga malamalama faʻafuaseʻi e ala i le faʻamalosia o le faʻaosoina, ma o latou masini e tutusa ma le laser semiconductor.SOA fa'amalosi mataua na'o se leisa semiconductor e aunoa ma ni manatu faaalia, ma o lona autu o le mauaina o mea mata'utia e ala i le fesuia'iina o le numera o mea ninii pe a otometi pe pamu eletise le semiconductor opitika.
Ituaiga oSOA Semiconductor fa'amalosi mata
E tusa ai ma le matafaioi a le SOA i faiga faʻatau, e mafai ona vaevaeina i ni vaega se fa: serial, booster, sui SOA, ma preamplifier.
1. Fa'aofi sa'o: maua maualuga, Psat feololo; Lower NF ma lalo ifo PDG, masani ona fesootai ma polarization tutoatasi SOA·
2. Faʻaleleia: Psat maualuga, maualalo maualalo, e masani ona faʻalagolago ile polarization;
3. Suiga: maualuga le faʻaumatiaina o faʻatusatusaga ma vave faʻatupuina / pa'ū taimi;
4. Fa'apipi'i muamua: talafeagai mo le mamao o felauaiga, NF maualalo, ma maua maualuga.
Tulaga lelei ole SOA Semiconductor optical amplifier
O le faʻaogaina o mea faʻapitoa e tuʻuina atu e le SOA i totonu o le bandwidth e tutoʻatasi lava i le umi o le galu o le faʻailoga faʻafuaseʻi.
Tu'i le taimi nei e pei o se fa'ailo pamu fa'ateleina, nai lo le pamu fa'apitoa.
Ona o lona lapo'a fa'atusatusa, e mafai ona tu'ufa'atasia le SOA ma le tele o masini fa'ata'ita'i fa'ata'ita'i i luga o se mea e tasi.
4. Latou te faʻaogaina le tekinolosi tutusa e pei o lasers diode.
E mafai e le SOA ona faʻaogaina i fesoʻotaʻiga faʻasalalauga faʻapitoa o le 1300 nm ma le 1550 nm, faʻatasi ai ma le lautele lautele (e oʻo atu i le 100 nm).
6. E mafai ona faʻapipiʻiina ma tuʻufaʻatasia e avea ma mea e muaʻi faʻapipiʻiina i le pito o le mea e maua ai mata.
SOA e mafai ona faʻaaogaina e fai ma faitotoa faʻaoga faigofie i fesoʻotaʻiga opitika WDM.
Tapula'a ole SOA Semiconductor optical amplifier
E mafai e le SOA ona tu'uina atu le mana opitika e o'o atu i le sefulu milliwatts (mW), lea e masani lava ona lava mo le fa'agaioia o alalaupapa tasi i so'otaga feso'ota'iga fiber optic. Ae ui i lea, o faiga WDM e ono mana'omia e oo atu i le tele mW o le mana i le alalaupapa.
2. Ona o le tu'ufa'atasiga o filo fa'apipi'i i totonu ma fafo atu o meataalo tu'ufa'atasia SOA e masani ona mafua ai le gau o fa'ailo, e tatau i le SOA ona tu'uina atu fa'aopoopoga o mea fa'apitoa e fa'aitiitia ai le a'afiaga o lenei gau i vaega o lo'o i totonu/tuuina atu o le vaega galue.
SOA e matua maaleale i le polarization o faʻailoga faʻapipiʻi.
4. Latou te fa'atupuina tulaga maualuga atu o le pisapisao i ala fa'asalalau fa'agaoioi nai lo fa'alava amplifiers.
Afai e tele auala fa'apitoa e fa'ateleina pe'ā mana'omia ile WDM talosaga, SOA o le a mafua ai le tele o feso'ota'iga.
