Meneneamplifier na gani na semiconductor
Amplifier na gani na semiconductor wani nau'in amplifier na gani ne wanda ke amfani da matsakaicin samun semiconductor. Yana kama da diode na laser, wanda madubin da ke ƙasan ƙarshensa ake maye gurbinsa da wani shafi mai haske. Ana watsa hasken siginar ta hanyar jagorar wave na semiconductor guda ɗaya. Girman da ke tsakanin jagorar wave shine micrometers 1-2 kuma tsawonsa yana kan tsari na 0.5-2mm. Yanayin jagorar wave yana da babban haɗuwa da yankin aiki (ƙarfafawa), wanda wutar lantarki ke turawa. Wutar da aka yi wa allura tana samar da wani yawan abubuwan ɗaukar kaya a cikin hanyar conduction, wanda ke ba da damar sauyawar hasken band conduction zuwa band valence. Ribar kololuwa tana faruwa ne lokacin da kuzarin photon ya ɗan fi ƙarfin bandgap. Ana amfani da amplifier na gani na SOA a tsarin sadarwa a cikin nau'in pigtails, tare da tsawon rai mai aiki kusan 1300nm ko 1500nm, yana samar da kusan 30dB na riba.
TheSOA semiconductor na gani amplifierna'urar haɗin PN ce mai tsarin rijiyar quantum mai ƙarfi. Hankali na gaba na waje yana juya adadin ƙwayoyin dielectric. Bayan hasken motsawa na waje ya shiga, ana samar da hasken da ke motsawa, wanda ke cimma haɓakar siginar gani. Duk hanyoyin canja wurin makamashi guda uku da ke sama suna wanzuwa a cikinSOA amplifier na ganiƘara siginar gani ta dogara ne akan fitar da hayaki mai ƙarfi. Tsarin sha da fitar da hayaki mai ƙarfi suna wanzuwa a lokaci guda. Ana iya amfani da shaƙar hasken famfo don hanzarta dawo da masu ɗaukar kaya, kuma a lokaci guda, famfon lantarki na iya aika electrons zuwa matakin makamashi mai girma (band ɗin gudanarwa). Lokacin da aka ƙara hasken kwatsam, zai samar da hayaniyar hasashe mai ƙarfi. SOA amplifier na gani ya dogara ne akan guntuwar semiconductor.
Kwamfutocin Semiconductor sun ƙunshi na'urori masu haɗaka, kamar GaAs/AlGaAs, InP/AlGaAs, InP/InGaAsP da InP/InAlGaAs, da sauransu. Waɗannan kuma kayan aikin ne don yin lasers na semiconductor. Tsarin jagorar raƙuman ruwa na SOA iri ɗaya ne ko kuma yayi kama da na lasers. Bambancin yana cikin cewa lasers suna buƙatar samar da rami mai amsawa a kusa da matsakaicin gain don samar da kuma kula da juyawar siginar gani. Za a ƙara girman siginar gani sau da yawa a cikin ramin kafin a fitar da shi. AAmplifier SOA(abin da muke tattaunawa a nan ya takaita ne ga amplifiers masu tafiya da ake amfani da su a yawancin aikace-aikace), haske yana buƙatar wucewa ta hanyar samun ƙarfin lantarki sau ɗaya kawai, kuma nunin baya ba shi da yawa. Tsarin amplifier na SOA ya ƙunshi yankuna uku: Yankin P, Yankin I (layin aiki ko node), da Yankin N. Layin aiki yawanci yana ƙunshe da kwantum Wells, wanda zai iya inganta ingancin juyawar photoelectric da rage ƙarfin lantarki.

An yi amfani da shi don canja wurin tashoshi
Yawanci ba wai kawai ana amfani da SOAs don ƙara girma ba: ana iya amfani da su a fagen sadarwa ta fiber optic, aikace-aikace bisa ga hanyoyin da ba na layi ba kamar samun jikewa ko polarization na cross-phase, waɗanda ke amfani da bambancin yawan masu ɗaukar kaya a cikin amplifier na gani na SOA don samun ma'aunin haske daban-daban. Ana iya amfani da waɗannan tasirin ga canja wurin tashoshi (juyawar raƙuman ruwa), canza tsarin daidaitawa, dawo da agogo, sake farfaɗo da sigina da gane tsari, da sauransu a cikin tsarin ninka girman raƙuman ruwa.
Tare da ci gaban fasahar da'irar optoelectronic da aka haɗa da kuma rage farashin masana'antu, filayen aikace-aikacen SOA semiconductor optical amplifier a matsayin amplifiers na asali, na'urorin gani masu aiki da kuma sassan tsarin za su ci gaba da faɗaɗa.
