Uchungechunge lwe-Optical amplifier: Isingeniso se-Semiconductor Optical Amplifier

I-Optical amplifieruchungechunge: Isingeniso Semiconductor Optical Amplifier

I-Semiconductor Optical amplifier(I-SOA) iyi-amplifier ebonakalayo esekelwe ku-semiconductor gain media. Ngokuyisisekelo ifana neshubhu le-laser ehlanganisiwe ye-fiber semiconductor, nesibuko sokugcina sithathelwa indawo ifilimu ephikisayo; Ama-waveguides atshekile angasetshenziswa ukuze kuqhutshekwe nokunciphisa ukubukeka kwesiphetho. Ukukhanya kwesignali kuvame ukudluliselwa nge-semiconductor yemodi eyodwa ye-waveguide, ene-lateral dimension ye-1-2 μ m nobude obucishe bube ngu-0.5-2mm. Imodi ye-waveguide igqagqana kakhulu nesifunda (sokukhulisa) esisebenzayo, esimpontshwa amandla amanje. Umjovo wamanje udala ukuminyana okuthile kwenkampani yenethiwekhi kubhendi yokuqhuba, okuvumela ukuguqulwa kokubona ukusuka kubhendi yokuqhuba ukuya kubhendi ye-valence. Ukuzuza okuphezulu kwenzeka emandleni e-photon ngaphezu kancane kwamandla e-bandgap.

Umgomo wokusebenza we-semiconductor optical amplifier
Ama-amplifiers optical Semiconductor (I-SOA) ikhulisa amasignali okukhanya kwesigameko ngokukhipha okukhuthazwayo, futhi indlela yawo iyafana neyama-semiconductor lasers.I-SOA Optical amplifieri-laser ye-semiconductor ngaphandle kwempendulo, futhi umnyombo wayo ukuthola inzuzo yokubona ngokuhlehlisa inani lezinhlayiya lapho i-semiconductor optical amplifier ikhishwa ngokukhanya noma ngogesi.
Izinhlobo zeI-SOA Semiconductor Optical amplifier
Ngokusho kwendima edlalwa yi-SOA ezinhlelweni zamakhasimende, zingahlukaniswa ngezigaba ezine: i-serial, i-booster, i-SOA yokushintsha, ne-preamplifier.
1. Ukufakwa okuqondile: inzuzo ephezulu, i-PSat emaphakathi; I-NF ephansi kanye ne-PDG ephansi, ngokuvamile ehlotshaniswa ne-polarization ezimele SOA·
2. Isithuthukisi: I-PSat Ephakeme, inzuzo ephansi, ngokuvamile incike ekuhlukaniseni;
3. Shintsha: isilinganiso esiphezulu sokuqothulwa kanye nesikhathi sokukhuphuka/sokuwa ngokushesha;
4. I-amplifier yangaphambili: ilungele amabanga amade okudlulisela, i-NF ephansi, kanye nenzuzo ephezulu.
Izinzuzo ze-SOA Semiconductor optical amplifier
Inzuzo ye-optical ehlinzekwa yi-SOA ngaphakathi komkhawulokudonsa izimele ngokuqhathaniswa ne-wavelength yesiginali ye-optical yesigameko.
Jova i-current njengesignali yepompo ekhulisiwe, esikhundleni sokumpompa okubonakalayo.
Ngenxa yobukhulu bayo obuhlangene, i-SOA ingahlanganiswa namadivayisi amaningi we-waveguide photonic ku-substrate eyodwa ye-planar.
4. Basebenzisa ubuchwepheshe obufanayo namalaser e-diode.
I-SOA ingasebenza kumabhendi we-spectral wokuxhumana we-1300 nm no-1550 nm, nge-bandwidth ebanzi (kufika ku-100 nm).
6. Zingacushwa futhi zihlanganiswe ukuze zisebenze njengama-preamplifiers ekugcineni kwe-optical receiver.
I-SOA ingasetshenziswa njengesango le-logic elula kumanethiwekhi we-WDM optical.

Imikhawulo ye-SOA Semiconductor optical amplifier
I-SOA inganikeza amandla okukhanya okukhiphayo afika emashumini ama-milliwatts (mW), anele ngokujwayelekile ukusebenza kwesiteshi esisodwa kuzixhumanisi zokuxhumana ze-fiber optic. Kodwa-ke, amasistimu e-WDM angase adinge amandla afinyelela kwangu-mW ambalwa ngesiteshi ngasinye.
2. Ngenxa yokuhlanganiswa kwama-fiber optical okufakwayo ngaphakathi nangaphandle kwama-chips ahlanganisiwe e-SOA ngokuvamile abangela ukulahlekelwa kwesignali, i-SOA kufanele inikeze inzuzo eyengeziwe ye-optical ukuze kuncishiswe umthelela walokhu kulahlekelwa ezicini zokufaka / zokukhiphayo zesifunda esisebenzayo.
I-SOA izwela kakhulu ku-polarization yezimpawu zokufaka optical.
4. Zenza amazinga aphezulu omsindo kumidiya esebenzayo kunama-fiber amplifiers.
Uma iziteshi zokukhanya eziningi zikhuliswa njengoba kudingeka ezinhlelweni ze-WDM, i-SOA izodala i-crosstalk enzima.
