Cod-weyneeye indhahataxane: Hordhac Semiconductor Optical Amplifier
Semiconductor Optical amplifier(SOA) waa cod-weyneeye indhaha ku salaysan warbaahinta faa'iidada semiconductor. Asal ahaan waxay la mid tahay tuubada laser semiconductor fiber-ka ah, iyadoo muraayadda dhamaadka lagu beddelay filim ka hortag ah; Hagaha mawjadaha leexleexan ayaa loo isticmaali karaa si loo sii yareeyo milicsiga dhamaadka. Iftiinka ishaadu inta badan waxa lagu kala qaadaa mawjadaha hal-hab ee semiconductor, oo leh cabbir geeseed 1-2 μm dhererkiisuna yahay ku dhawaad 0.5-2mm. Habka waveguide wuxuu si weyn ugu dul-dabaalayaa gobolka firfircoon (amplification), kaas oo lagu shubo hadda. Durida hadda waxay abuurtaa cufnaanta side qaarkood ee band-wadaha, taas oo u oggolaanaysa kala-guurka indhaha ee band- conduction ilaa band valence. Faa'iidada ugu badan waxay ku dhacdaa tamarta photon in yar oo ka sarreysa tamarta bandgap.
Mabda'a shaqada ee cod-weyneeye indho-indhayneed
Semiconductor Optical amplifiers (SOA) Waxay ku kordhiyaan calaamadaha iftiinka dhacdada iyada oo loo marayo qiiqa la kiciyey, farsamadooduna waxay la mid tahay kan laysarka semiconductor.Cod-weyneeye indhaha SOAwaa laser semiconductor oo kaliya iyada oo aan jawaab celin lahayn, udub dhexaadkeeduna waa in la helo faa'iido muuqaal ah iyada oo la beddelayo tirada qaybaha marka cod-weyneeye-gacan-yar-yareedka si muuqaal ah ama koronto ah lagu shubo.
NoocyadaSOA Semiconductor optical amplifier
Marka loo eego doorka ay SOA ka ciyaartay nidaamka macaamiisha, waxa loo qaybin karaa afar qaybood: taxane, xoojiye, beddelaadda SOA, iyo horudhac.
1. Gelitaanka tooska ah: faa'iido sare, Psat dhexdhexaad ah; NF hoose iyo PDG hoose, oo inta badan la xidhiidha polarization madax banaan SOA ·
2. Kobciye: Sare Psat, faa'iido hoose, badanaa waxay ku xiran tahay polarization;
3. Bedesho: saamiga dabar goynta sare iyo wakhtiga kor u kaca/dhicista degdega ah;
4. Pre amplifier: ku habboon fogaanta gudbinta dheer, NF hoose, iyo faa'iidada sare.
Faa'iidooyinka SOA Semiconductor optical amplifier
Faa'iidada indhaha ee ay SOA ku bixiso xadhkaha xadhkaha goosha ayaa ah mid ka madax banaan mawjadaha dhererka isha ee dhacdada.
Duri hadda sida calaamada bamka la xoojiyay, halkii aad ka ahaan lahayd bamgaraynta indhaha.
Cabbirkeeda is haysta awgeed, SOA waxaa lagu dhex dari karaa waveguide qalabyo sawir-qaade oo badan oo ku yaalla hal substrate oo keliya.
4. Waxay adeegsadaan tignoolajiyada la midka ah sida leysarka diode-ka.
SOA waxay ku shaqayn kartaa xadhkaha isgaadhsiinta ee 1300 nm iyo 1550 nm, oo leh xajmi ballaadhan (ilaa 100 nm).
6. Waa la habayn karaa oo waa la isku dari karaa si ay ugu adeegaan sidii hore-u-hawlgalayaasha dhammaadka qaataha indhaha.
SOA waxa loo isticmaali karaa sidii albaab macquul ah oo fudud ee shabakadaha indhaha ee WDM.
Xaddidaadda SOA Semiconductor optical amplifier
SOA waxay ku siin kartaa wax soo saarka awoodda indhaha ilaa tobanaan milliwatts (mW), taas oo caadi ahaan ku filan hawlgalka hal kanaal ee isku xirka isgaarsiinta fiber optic. Si kastaba ha ahaatee, nidaamyada WDM waxa laga yaabaa inay u baahdaan ilaa dhowr mW oo awood ah kanaalkaba.
2. Sababtoo ah isku dhafka fiilooyinka indhaha ee gudaha iyo ka baxa chips-ka isku-dhafan ee SOA oo badanaa keena luminta calaamadaha, SOA waa inay bixiso faa'iido muuqaal ah oo dheeri ah si loo yareeyo saameynta khasaarahan ee dhinacyada wax-soo-saarka / soo-saarka ee gobolka firfircoon.
SOA waxay aad ugu nugul tahay kala-soocida calaamadaha indhaha.
4. Waxay abuuraan heerar sare oo qaylo ah warbaahinta firfircoon marka loo eego cod-weyneyaasha fiber-ka.
Haddii kanaalada indhaha ee badan la kordhiyo sida loogu baahan yahay codsiyada WDM, SOA waxay keeni doontaa hadal isdhaafsi daran.
