Kodi semiconductor Optical amplifier imakwaniritsa bwanji kukulitsa?

Zikuyenda bwanjisemiconductor kuwala amplifierkukwaniritsa amplification?

Pambuyo pakubwera kwa nthawi ya kulumikizana kwakukulu kwa fiber fiber, ukadaulo wa optical amplification wakula mwachangu.Optical amplifierskukulitsa ma siginecha owoneka bwino potengera kukhudzidwa kwa ma radiation kapena kubalalitsa kokondoweza. Malinga ndi mfundo yogwirira ntchito, ma amplifiers owoneka amatha kugawidwa mu semiconductor optical amplifiers (SOA) ndioptical fiber amplifiers. Mwa iwo,semiconductor kuwala amplifiersamagwiritsidwa ntchito kwambiri mukulankhulana kwa kuwala chifukwa cha ubwino wa wide gain band, kuphatikiza kwabwino komanso kutalika kwa kutalika kwa mafunde. Amapangidwa ndi zigawo zogwira ntchito komanso zopanda pake, ndipo dera logwira ntchito ndilo gawo lopindula. Pamene chizindikiro cha kuwala chikudutsa m'dera logwira ntchito, chimapangitsa kuti ma electron awonongeke ndi kubwerera ku nthaka pansi monga ma photon, omwe ali ndi kutalika kofanana ndi chizindikiro cha kuwala, motero amakulitsa chizindikiro cha kuwala. Semiconductor Optical amplifier imasintha chonyamulira cha semiconductor kukhala chosinthira kumbuyo ndikuyendetsa pakali pano, imakulitsa kukula kwa mbewu yomwe idalowetsedwa, ndikusunga mawonekedwe oyambira a kuwala kwa mbewu monga polarization, m'lifupi mwake komanso pafupipafupi. Ndi kuwonjezeka kwa ntchito yamakono, mphamvu yotulutsa kuwala imawonjezekanso mu ubale wina wogwira ntchito.

Koma kukula uku sikuli kopanda malire, chifukwa ma semiconductor optical amplifiers ali ndi chodabwitsa chochulukitsa. Chochitikacho chikuwonetsa kuti pamene mphamvu yowonjezera yowonjezera imakhala yosasinthasintha, phindu limawonjezeka ndi kuwonjezeka kwa jekeseni wonyamula jekeseni, koma pamene jekeseni wonyamula jekeseni ndi waukulu kwambiri, phindu lidzakhutitsidwa kapena kuchepa. Pamene ndende ya chonyamulira jekeseni imakhala yosasinthasintha, mphamvu yotulutsa imawonjezeka ndi kuwonjezeka kwa mphamvu yolowera, koma mphamvu ya kuwala ikakhala yaikulu kwambiri, kuchuluka kwa magwiritsidwe ntchito chifukwa cha cheza chosangalatsa ndi chachikulu kwambiri, zomwe zimapangitsa kuti machulukitsidwe kapena kuchepa. Chifukwa cha kukhutitsidwa kwa phindu ndikulumikizana pakati pa ma electron ndi ma photon muzinthu zogwira ntchito. Kaya ma photon amapangidwa mu gain medium kapena photons zakunja, mlingo umene cheza chokondoweza chimadya zonyamulira zimagwirizana ndi mlingo umene zonyamulira zimadzaza ndi mphamvu yofanana ndi nthawi. Kuphatikiza pa ma radiation olimbikitsidwa, kuchuluka kwa chonyamulira komwe kumagwiritsidwa ntchito ndi zinthu zina kumasinthanso, zomwe zimakhudzanso kukhudzika kwachuma.

Popeza ntchito yofunika kwambiri ya semiconductor optical amplifiers ndiyo kukweza kwa mzere, makamaka kuti akwaniritse kukulitsa, angagwiritsidwe ntchito ngati amplifiers amphamvu, amplifiers line ndi preamplifiers mu machitidwe oyankhulana. Pamapeto otumizira, semiconductor kuwala amplifier amagwiritsidwa ntchito ngati amplifier mphamvu kupititsa patsogolo mphamvu yotulutsa kumapeto kwa dongosolo, zomwe zitha kukulitsa kwambiri mtunda wolumikizana ndi thunthu la dongosolo. Mu mzere wotumizira, semiconductor optical amplifier ingagwiritsidwe ntchito ngati amplifier yolumikizira mzere, kuti mtunda wobwereza wobwereza uwonjezekenso ndi kudumpha ndi malire. Pamapeto olandila, semiconductor optical amplifier ingagwiritsidwe ntchito ngati preamplifier, yomwe imatha kusintha kwambiri chidwi cha wolandila. Makhalidwe ochulukitsa a semiconductor optical amplifiers apangitsa kuti phindu pa pang'ono ligwirizane ndi katsatidwe kakang'ono kapitako. Zotsatira za chitsanzo pakati pa mayendedwe ang'onoang'ono amathanso kutchedwa cross-gain modulation effect. Njirayi imagwiritsa ntchito kuchuluka kwa mawerengero a kusintha kwa phindu pakati pa mayendedwe angapo ndikuyambitsa mafunde apakati opitilira muyeso kuti asunge mtengowo, motero kukakamiza kupindula konse kwa amplifier. Ndiye kusintha kwa kusintha kwa phindu pakati pa mayendedwe kumachepetsedwa.

Ma semiconductor optical amplifiers ali ndi mawonekedwe osavuta, ophatikizana osavuta, ndipo amatha kukulitsa ma sign a kuwala kwa mafunde osiyanasiyana, ndipo amagwiritsidwa ntchito kwambiri pakuphatikiza mitundu yosiyanasiyana ya ma laser. Pakadali pano, ukadaulo wophatikizira wa laser wozikidwa pa semiconductor optical amplifiers ukupitilirabe kukhwima, koma zoyeserera ziyenera kupangidwa muzinthu zitatu zotsatirazi. Chimodzi ndicho kuchepetsa kutayika kwa kugwirizana ndi kuwala kwa fiber. Vuto lalikulu la semiconductor optical amplifier ndikuti kutayika kolumikizana ndi ulusi kumakhala kwakukulu. Pofuna kupititsa patsogolo kugwirizanitsa, lens ikhoza kuwonjezeredwa ku makina ogwirizanitsa kuti achepetse kutayika kwa kuwonetserako, kupititsa patsogolo kufanana kwa mtengowo, ndi kukwaniritsa kugwirizanitsa kwakukulu. Chachiwiri ndikuchepetsa kukhudzidwa kwa polarization kwa semiconductor optical amplifiers. Chikhalidwe cha polarization makamaka chimatanthawuza kukhudzidwa kwa polarization kwa kuwala kwa chochitikacho. Ngati semiconductor optical amplifier sichikonzedwa mwapadera, bandwidth yothandiza ya phindu idzachepetsedwa. Kapangidwe ka chitsime cha Quantum kumatha kupititsa patsogolo kukhazikika kwa ma semiconductor optical amplifiers. Ndizotheka kuphunzira mawonekedwe osavuta komanso apamwamba kwambiri kuti muchepetse kukhudzidwa kwa polarization kwa semiconductor optical amplifiers. Chachitatu ndi kukhathamiritsa kwa Integrated ndondomeko. Pakalipano, kuphatikiza kwa semiconductor optical amplifiers ndi ma lasers ndizovuta kwambiri komanso zovuta pakukonza luso, zomwe zimapangitsa kuti pakhale kutayika kwakukulu kwa kufalitsa ma siginecha ndi kutayika kwa chipangizocho, ndipo mtengo wake ndi wokwera kwambiri. Chifukwa chake, tiyenera kuyesa kukhathamiritsa kapangidwe ka zida zophatikizika ndikuwongolera kulondola kwa zida.

Muukadaulo wolumikizirana ndi kuwala, ukadaulo waukadaulo wokulitsa ndi imodzi mwaukadaulo wothandizira, ndipo ukadaulo wa semiconductor optical amplifier ukukula mwachangu. Pakalipano, machitidwe a semiconductor optical amplifiers akhala akuyenda bwino kwambiri, makamaka pakupanga matekinoloje amakono amakono monga wavelength division multiplexing kapena optical switching modes. Ndi chitukuko cha mafakitale azidziwitso, ukadaulo wokulitsa mawonekedwe oyenerera magulu osiyanasiyana ndi ntchito zosiyanasiyana udzayambitsidwa, ndipo chitukuko ndi kafukufuku waukadaulo watsopano mosakayikira zipangitsa ukadaulo wa semiconductor optical amplifier kuti upitilize kukula ndikuyenda bwino.
