Isikhulisi sokubonauchungechunge: Isingeniso se-Semiconductor Optical Amplifier
I-amplifier ye-semiconductor optical(SOA) iyi-optical amplifier esekelwe kumidiya yokuthola amandla e-semiconductor. Empeleni ifana ne-fiber coupled semiconductor laser tube, lapho isibuko sokugcina sithathelwe indawo yifilimu ephikisana nokukhanya; Ama-waveguide athambekile angasetshenziswa ukunciphisa kakhulu ukukhanya kokuphela. Ukukhanya kwesignali kuvame ukudluliselwa nge-waveguide yemodi eyodwa ye-semiconductor, enobukhulu obuseceleni obungu-1-2 μ m kanye nobude obungaba ngu-0.5-2mm. Imodi ye-waveguide ihlangana kakhulu nesifunda esisebenzayo (sokukhulisa), esidonswa amandla kagesi. Ukujova amandla kagesi kukhiqiza ubuningi obuthile bokuthwala ebhendini lokuhambisa, okuvumela ukuguquka kokukhanya kusuka ebhendini lokuhambisa amandla kuya ebhendini le-valence. Ukwanda okukhulu kwenzeka emandleni e-photon ngaphezu kancane kwamandla e-bandgap.
Isimiso sokusebenza se-amplifier ye-optical semiconductor
Ama-amplifier optical e-semiconductor (I-SOA) zikhulisa izimpawu zokukhanya kwezehlakalo ngokukhishwa okuvuselelwe, futhi indlela yazo yokusebenza ifana neye-semiconductor lasers.I-amplifier ye-SOA opticaliyi-laser ye-semiconductor nje engenampendulo, futhi umongo wayo ukuthola inzuzo ye-optical ngokuguqula inani lezinhlayiya lapho i-amplifier ye-optical ye-semiconductor iphampulwa nge-optical noma ngogesi.
Izinhlobo zeI-amplifier ye-optical ye-SOA Semiconductor
Ngokwendima edlalwa yi-SOA ezinhlelweni zamakhasimende, zingahlukaniswa ngezigaba ezine: i-serial, i-booster, i-switching SOA, kanye ne-preamplifier.
1. Ukufakwa okuqondile: inzuzo ephezulu, i-Psat ephakathi nendawo; i-NF ephansi kanye ne-PDG ephansi, ngokuvamile ehlotshaniswa ne-SOA ezimele yokwehlukanisa
2. Isithuthukisi: I-Psat Ephakeme, inzuzo ephansi, ngokuvamile incike ekuhlukaniseni;
3. Ushintsho: isilinganiso esiphezulu sokuphela kanye nesikhathi sokukhuphuka/sokuwa okusheshayo;
4. I-amplifier yangaphambi kwesikhathi: ifanelekela amabanga amade okudlulisa, i-NF ephansi, kanye nokuzuza okuphezulu.
Izinzuzo ze-amplifier ye-SOA Semiconductor optical
Inzuzo yokukhanya enikezwa yi-SOA ngaphakathi komkhawulokudonsa ayincikile kakhulu kubude besikhathi besignali yokukhanya yesigameko.
Faka ugesi njengesignali yephampu ekhulisiwe, kunokuba uphompe nge-optical.
Ngenxa yobukhulu bayo obuncane, i-SOA ingahlanganiswa namadivayisi amaningi e-photonic eqondisa amagagasi ku-substrate eyodwa ehleliwe.
4. Basebenzisa ubuchwepheshe obufanayo nama-diode lasers.
I-SOA ingasebenza kuma-band e-spectral okuxhumana angu-1300 nm kanye no-1550 nm, nge-bandwidth ebanzi (kufika ku-100 nm).
6. Zingalungiswa futhi zihlanganiswe ukuze zisebenze njenge-preamplifier ekugcineni kwe-optical receiver.
I-SOA ingasetshenziswa njengesango elilula le-logic kumanethiwekhi e-optical e-WDM.
Imikhawulo ye-amplifier ye-optical ye-SOA Semiconductor
I-SOA inganikeza amandla okukhipha optical angafika kumashumi ama-milliwatts (mW), ngokuvamile anele ukusebenza kwesiteshi esisodwa kuzixhumanisi zokuxhumana ze-fiber optic. Kodwa-ke, izinhlelo ze-WDM zingadinga amandla afinyelela kuma-mW amaningana ngesiteshi ngasinye.
2. Ngenxa yokuhlanganiswa kwemicu ye-optical yokufaka ngaphakathi nangaphandle kwama-chip ahlanganisiwe e-SOA okuvame ukubangela ukulahleka kwesiginali, i-SOA kumele inikeze inzuzo eyengeziwe ye-optical ukuze kuncishiswe umthelela walokhu kulahlekelwa ezicini zokufaka/zokukhipha zesifunda esisebenzayo.
I-SOA ibucayi kakhulu ekuhlukanisweni kwezimpawu zokukhanya ezifakiwe.
4. Zikhiqiza amazinga aphezulu omsindo ezindaweni ezisebenzayo kunezikhulisa-msindo zefayibha.
Uma iziteshi eziningi ze-optical zikhuliswa njengoba kudingeka kuzinhlelo zokusebenza ze-WDM, i-SOA izobangela ukukhuluma okujulile.
