Cikakken fahimtar masu gyaran lantarki na electro-optic
Mai amfani da na'urar auna haske ta lantarki (Electro-optic modulator)EOM) wani na'urar canza siginar lantarki ce wadda ke amfani da siginar lantarki don sarrafa siginar gani, galibi ana amfani da ita a tsarin canza siginar gani a fannin fasahar sadarwa.
Ga cikakken bayani game da na'urar sarrafa na'urar lantarki ta electro-optic:
1. Babban ƙa'idarna'urar sarrafa na'urar lantarki (electro-optical modulator)ya dogara ne akan tasirin electro-optic, wato, ma'aunin haske na wasu kayan zai canza ƙarƙashin aikin filin lantarki da aka yi amfani da shi. Yayin da raƙuman haske ke ratsa waɗannan lu'ulu'u, halayen yaɗuwa suna canzawa tare da filin lantarki. Ta amfani da wannan ƙa'ida, yanayin yanayin, girma ko polarization nana ganiAna iya sarrafa siginar ta hanyar canza filin lantarki da aka yi amfani da shi.
2. Tsarin da abun da ke ciki. Ma'aunin lantarki gabaɗaya ya ƙunshi hanyoyin gani, amplifiers, filters da masu canza haske. Bugu da ƙari, ya haɗa da muhimman abubuwan da ke ciki kamar direbobi masu sauri, zaruruwan gani da lu'ulu'u na piezoelectric. Tsarin ma'aunin lantarki na iya bambanta dangane da yanayin daidaitawa da buƙatun aikace-aikacensa, amma yawanci ya haɗa da sassa biyu: ma'aunin lantarki na lantarki da ma'aunin lantarki na lantarki.
3. Yanayin daidaitawa Mai amfani da na'urar lantarki (Electro-optical modulator) yana da manyan hanyoyin daidaitawa guda biyu:daidaitawar lokacida kuma daidaita ƙarfi. Daidaita lokaci: Matakin mai ɗaukar kaya yana canzawa yayin da siginar da aka daidaita ta canza. A cikin Pockels electro-optic modulator, hasken mitar mai ɗaukar kaya yana ratsa ta cikin kristal ɗin piezoelectric, kuma lokacin da aka yi amfani da ƙarfin lantarki mai daidaitawa, ana samar da filin lantarki a cikin kristal ɗin piezoelectric, wanda ke haifar da canjin ma'aunin haskensa, don haka yana canza yanayin hasken.Daidaita ƙarfi: Ƙarfin (ƙarfin haske) na mai ɗaukar haske yana canzawa yayin da siginar da aka daidaita ta canza. Yawanci ana samun daidaitaccen ƙarfin ta amfani da na'urar daidaita ƙarfin Mach-Zehnder, wacce take daidai da ma'aunin interferometer na Mach-Zehnder. Bayan an daidaita hasken biyu ta hannun juyawa na lokaci tare da ƙarfi daban-daban, a ƙarshe ana tsoma su don samun siginar gani mai daidaitawa da ƙarfi.
4. Yankunan aikace-aikacen Masu daidaita wutar lantarki suna da aikace-aikace iri-iri a fannoni daban-daban, gami da amma ba'a iyakance ga: sadarwa ta gani ba: A cikin tsarin sadarwa mai sauri, ana amfani da masu daidaita wutar lantarki don canza siginar lantarki zuwa siginar gani don cimma rikodin bayanai da watsawa. Ta hanyar daidaita ƙarfi ko matakin siginar gani, ana iya cimma ayyukan sauya haske, sarrafa saurin daidaitawa da daidaita siginar. Spectroscopy: Ana iya amfani da masu daidaita wutar lantarki azaman abubuwan da ke cikin masu nazarin bakan gani don nazarin bakan gani da aunawa. Ma'aunin fasaha: masu daidaita wutar lantarki suma suna taka muhimmiyar rawa a cikin tsarin radar, binciken lafiya da sauran fannoni. Misali, a cikin tsarin radar, ana iya amfani da shi don daidaita sigina da kuma rage gudu; A cikin ganewar asibiti, ana iya amfani da shi don hoton gani da magani. Sabbin na'urorin daukar hoto: Ana iya amfani da masu daidaita wutar lantarki don ƙera sabbin na'urorin daukar hoto, kamar masu canza wutar lantarki, masu raba wutar lantarki, da sauransu.
5. Amfani da rashin amfani Mai daidaita wutar lantarki (Electro-optic modulator) yana da fa'idodi da yawa, kamar aminci mai yawa, ƙarancin amfani da wutar lantarki, sauƙin shigarwa, ƙaramin girma da sauransu. A lokaci guda, yana da kyawawan halaye na lantarki da ikon hana tsangwama, wanda za'a iya amfani da shi don watsawa ta hanyar intanet da kuma buƙatun sarrafa sigina iri-iri. Duk da haka, mai daidaita wutar lantarki yana da wasu gazawa, kamar jinkirin watsa sigina, mai sauƙin shiga cikin raƙuman lantarki na waje. Saboda haka, lokacin amfani da mai daidaita wutar lantarki, yana da mahimmanci a zaɓi samfurin da ya dace bisa ga ainihin buƙatun aikace-aikacen don cimma kyakkyawan tasirin daidaitawa da aiki. A taƙaice, mai daidaita wutar lantarki muhimmin mai canza wutar lantarki ne, wanda ke da fa'ida mai yawa a fannoni da yawa kamar sadarwa ta gani, spectroscopy da auna fasaha.
Tare da ci gaba da ci gaban kimiyya da fasaha da kuma karuwar bukatar na'urorin gani masu inganci, za a kara bunkasa da kuma amfani da na'urorin lantarki masu amfani da hasken rana.
