I-Optical AmplifierUchungechunge: Isingeniso ku-Semiconductor Optical Amplifier

I-Semicondector Optical Amplifier(SOA) yi-amplifier yokubona esekelwe kwimidiya ye-semiconductor. Empeleni kufana ne-fiber counepled lemiconductor laser tube, ngesibuko sokuphela esifakwe esikhundleni sefilimu ekhombisa i-anti; Ama-wavegcuides athambile angasetshenziswa ukuthuthukisa ukuphela kokuvezwa. Ukukhanya kwesiginali kuvame ukudluliselwa nge-semicenductor eyodwa ye-waveguide, ngokubuyiselwa kwamuva kwe-1-2 μ m kanye nobude be-0.5-mm. Imodi ye-WaveGuide kakhulu iqhubeka kakhulu nesifunda esisebenzayo (se-Amplification), esidonswa yimanje. Ukujova kwamanje kwakha isilinganiselo esithile senkampani esele ebhendini yokuhumusha, okuvumela izinguquko ze-optical kusuka ebhendi lokuvumelanisa ku-valence band. Ukuthola okuphezulu kwenzeka kuma-Photon Energy kancane ngenhla kwe-bandgap energy.

Umgomo Wokusebenza Kwe-Semiconductor Optical Amplifier
Ama-semicondector appifiers (Inyoka) Khulisa amasiginali okukhanya kwesigameko ngokuphuma okuvuselelayo, futhi inqubo yawo iyafana naleyo ye-semiconductor lasers.I-SOA Optical AmplifierI-laser ye-semiconductor ngaphandle kwempendulo, futhi umnyombo wayo ukuthola inzuzo ye-optical ngokubuyisa inani lezinhlayiya lapho i-semiconductor amplifier igcwele ngokoqobo noma ngogesi.
Izinhlobo zeI-SOA semiconductor amplifier
Ngokwendima edlalwa yi-SOA ezinhlelweni zamakhasimende, zingahlukaniswa ngezigaba ezine: i-serial, i-booster, i-switch soa, kanye ne-preamlifier.
1. Ukufakwa okuqondile: inzuzo ephezulu, i-psat elinganiselayo; I-NF ephansi ne-PDG ephansi, evame ukuhlotshaniswa ne-polarization ezimele i-Soa · · · · · ·
2
3. Shintsha: isilinganiso esiphakeme sokuqothulwa kanye nokuvuka okusheshayo / isikhathi sokuwa;
I-4. I-Amplifier yangaphambili: Ilungele amabanga amade okuhambisa, i-NF ephansi, kanye nenzuzo ephezulu.
Izinzuzo ze-SOA semiconductor amplifier
Ukutholwa kwe-Optical okunikezwe yi-SOA ngaphakathi kwe-bandwidth kuzimele ngokungafani nesibonakaliso sesigameko sokwenziwa kwezigameko.
Faka njengamanje njengesiginali yepompo ekhulisiwe, kunokuba impande yokubona.
Ngenxa yosayizi wayo ocwecwe, i-SOA ingahlanganiswa namadivayisi amaningi we-waveguide photonic ku-substrate eyodwa yeplanethi.
4. Basebenzisa ubuchwepheshe obufanayo ne-diode lasers.
I-SOA ingasebenza kumabhendi wokubala wokuxhumana angu-1300 nm no-1550 nm, nge-bandwidth ebanzi (kuze kube yi-100 NM).
I-6. Zingalungiswa futhi zihlanganiswe ukuze zisebenze njengezilungiselelo ezikhona endaweni etholwayo.
I-SOA ingasetshenziswa njengesango elilula le-logic kumanethiwekhi we-WDM Optical.

Ukulinganiselwa kwe-SOA semiconductor amplifier
I-SOA inganikeza amandla okuphuma kwamandla okuphuma kumashumi ama-milliwatts (MW), ajwayele ukwanele ekusebenzeni kwesiteshi esisodwa kwizixhumanisi zokuxhumana ze-fiber optic. Kodwa-ke, amasistimu we-WDM angadinga kuze kube yilapho ama-MW amaningi wamandla ngesiteshi ngasinye.
2. Ngenxa yokuhlanganiswa kwemicu yokufaka okufakwayo ngaphakathi nangaphandle kwama-chips ahlanganisiwe we-SOA kuvame ukudala ukulahleka kwesiginali, i-SUA kumele inikeze ukuzuza okwengeziwe kokuncipha ukuze unciphise umthelela walokhu kulahleka kwezindawo zokufaka / zokukhipha zesifunda esisebenzayo.
I-SOA izwela kakhulu ekuhlolweni kwezimpawu zokufaka ezifakiwe.
I-4. Bakhiqiza amazinga aphezulu omsindo kumidiya esebenzayo kunezikhulisi ze-fiber.
Uma iziteshi eziningi ze-Optical zikhuliswa njengoba zidingeka kuzinhlelo zokusebenza ze-WDM, i-SOA izodala i-crosstalk enkulu.
