Wowonjezera semiconductor Optical amplifier

Kuwongoleredwasemiconductor kuwala amplifier

Chowonjezera chowonjezera cha semiconductor Optical amplifier ndi mtundu wosinthidwa wa semiconductor optical amplifier (SOA Optical amplifier). Ndi amplifier yomwe imagwiritsa ntchito semiconductors kuti ipereke mwayi wopeza. Mapangidwe ake ndi ofanana ndi a Fabry-Pero laser diode, koma kawirikawiri nkhope yomaliza imakutidwa ndi filimu yotsutsa-reflection. Mapangidwe aposachedwa akuphatikizapo mafilimu otsutsa-reflection komanso ma waveguides ndi zigawo zazenera, zomwe zingachepetse mawonekedwe a nkhope yomaliza kukhala pansi pa 0.001%. Ma amplifiers opangidwa bwino kwambiri amakhala othandiza makamaka pokulitsa ma siginecha (owoneka), chifukwa pali chiwopsezo chachikulu cha kutayika kwa ma siginecha panthawi yotumiza mtunda wautali. Popeza chizindikiro cha kuwala chimakulitsidwa mwachindunji, njira yachikhalidwe yosinthira kukhala chizindikiro chamagetsi isanakhale yowonjezereka. Chifukwa chake, kugwiritsa ntchitoSOAkwambiri bwino kufala kwa dzuwa. Ukadaulo uwu nthawi zambiri umagwiritsidwa ntchito pogawa mphamvu ndikulipira chiwongola dzanja mumanetiweki a WDM.

Zochitika zantchito

Mu makina opangira ma fiber optical, ma semiconductor optical amplifiers (SOA) angagwiritsidwe ntchito m'malo angapo ogwiritsira ntchito kuti apititse patsogolo ntchito ndi kutumizira mtunda wa njira yolumikizirana. Zotsatirazi ndi zina zomwe zimagwiritsidwa ntchito pogwiritsira ntchito SOA amplifier mu optical fiber communication systems:

Woyamba: SOAamplifier kuwalaangagwiritsidwe ntchito ngati preamplifier pa mapeto olandira kuwala mu kachitidwe kulankhulana mtunda wautali ndi ulusi kuwala kuposa makilomita 100, kukulitsa kapena kukulitsa mphamvu ya chizindikiro linanena bungwe mu mtunda wautali makina kuwala CHIKWANGWANI kulankhulana machitidwe, potero kubweza mtunda wosakwanira kufala chifukwa cha kutulutsa kofooka kwa zizindikiro zazing'ono. Kuphatikiza apo, SOA ingagwiritsidwenso ntchito kuyika ukadaulo wa optical network regeneration tekinoloje mumayendedwe olumikizirana ma fiber.

Kusinthika kwazizindikiro zonse: M'mawonekedwe a kuwala, pamene mtunda wotumizira ukuwonjezeka, zizindikiro za kuwala zidzawonongeka chifukwa cha kuchepa, kufalikira, phokoso, nthawi ya jitter ndi crosstalk, ndi zina zotero. Kusinthika kwa ma siginecha onse kumatanthawuza kukulitsanso, kukonzanso ndikukonzanso nthawi. Kukulitsa kwina kutha kutheka ndi amplifiers owoneka ngati semiconductor optical amplifiers, EDFA ndi Raman amplifiers (RFA).

Mu optical fiber sensing systems, semiconductor optical amplifiers (SOA amplifier) angagwiritsidwe ntchito kukulitsa zizindikiro za kuwala, potero kupititsa patsogolo kukhudzidwa ndi kulondola kwa masensa. Zotsatirazi ndi zina zomwe zimagwiritsidwa ntchito pogwiritsira ntchito SOA m'makina a optical fiber sensing:

Muyezo wa minyewa ya kuwala: Konzani chingwe cha kuwala pa chinthu chomwe mtundu wake uyenera kuyezedwa. Pamene chinthucho chikugwedezeka, kusintha kwa zovuta kumayambitsa kusintha pang'ono kwa kutalika kwa fiber optical, motero kusintha kutalika kwa mawonekedwe kapena nthawi ya chizindikiro cha kuwala kwa PD sensor. SOA amplifier imatha kukwaniritsa magwiridwe antchito apamwamba pokulitsa ndikusintha chizindikiro cha kuwala.

Kuyeza kwa mphamvu ya kuwala kwa fiber: Pophatikiza ulusi wa kuwala ndi zinthu zogwira mtima, pamene chinthu chikagwedezeka, zimayambitsa kusintha kwa kuwonongeka kwa kuwala mkati mwa kuwala kwa fiber. SOA ingagwiritsidwe ntchito kukulitsa chizindikiro chofooka ichi kuti chikwaniritse muyeso wovuta kwambiri.

The semiconductor optical amplifier SOA ndi chipangizo chofunika kwambiri pamagulu a optical fiber communication ndi optical fiber sensing. Mwa kukulitsa ndi kukonza ma siginecha owoneka bwino, kumawonjezera magwiridwe antchito adongosolo komanso kumva bwino. Mapulogalamuwa ndi ofunikira kuti tikwaniritse kulumikizana kwamphamvu kwambiri, kokhazikika komanso kodalirika komanso kumveka bwino komanso koyenera kwa fiber fiber.
