Ka'idar aiki na gama garimai daidaita ƙarfi

Ka'idar masu daidaita ƙarfin aiki ta bambanta dangane da nau'in. Ga ƙa'idodin aiki na masu daidaita ƙarfin aiki na gama gari:

1. Madaidaitan Intensity na Mach Zehnder (Mai Gyaran MZM)
Babban ƙa'ida: Dangane da tasirin tsangwama na haske. Ka'idarDaidaita ƙarfin lantarki (electro-optical dynamization)shine amfani da tasirin electro-optic na lu'ulu'u da kuma cimma daidaiton ƙarfi bisa ga ƙa'idar tsangwama ta hasken polarized. Tasirin electro-optic na lu'ulu'u yana nufin abin da ke faruwa inda ma'aunin refractive na lu'ulu'u ke canzawa ƙarƙashin aikin filin lantarki na waje, yana haifar da bambancin lokaci tsakanin haske da ke ratsa lu'ulu'u a cikin al'amuran polarization daban-daban, ta haka ne ke canza yanayin polarization na haske.
Tsarin aiki:
Hasken shigarwa yana raba hanyoyi biyu ta hanyar mai raba haske kuma yana ratsa ta hannun jagoran raƙuman ruwa guda biyu bi da bi.
Sanya ƙarfin lantarki na waje a kan ɗaya ko duka hannayen biyu sannan a yi amfani da tasirin electro-optic (kamar tasirin electro-optic na layi na lithium niobate crystal) don canza ma'aunin refractive na jagorar waveguide, ta haka ne za a canza yanayin raƙuman haske a cikin hannaye.
An sake haɗa haskoki biyu na haske a ƙarshen fitarwa, kuma saboda bambance-bambancen matakai daban-daban, tsangwama mai gina jiki ko illa na iya faruwa, wanda ke haifar da canje-canje a cikin ƙarfin hasken fitarwa tare da ƙarfin lantarki.
Idan bambancin mataki tsakanin hannayen biyu shine 0, ƙarfin hasken fitarwa yana kan iyakarsa (a yanayin "kunnawa"); Idan bambancin mataki shine π, ƙarfin hasken fitarwa yana raguwa (a yanayin "kashewa"), yana cimma daidaiton ƙarfi.

2. Mai Daidaita Intensity Modulator na Electro Absorption (EAM)
Babban ƙa'ida: Amfani da tasirin electroabsorption na kayan rijiyar kwantum.
Tsarin aiki:
Yin amfani da filin lantarki na waje akan kayan semiconductor na rijiyar quantum yana canza ma'aunin sha na kayan.
Idan haske ya ratsa ta cikin wani abu, ƙarfinsa yana canzawa saboda canje-canje a cikin ma'aunin sha, ta haka ne ake cimma daidaiton ƙarfin haske.
Yawanci yana buƙatar juyawar ra'ayi, kuma siginar wutar lantarki ta shigarwa tana da alaƙa mai ƙarfi da ƙarfin hasken fitarwa, wanda hakan ya sa ya dace da sadarwa mai sauri ta gani.

3.mai daidaita ƙarfin acousto-optic
Babban ƙa'ida: Dangane da tasirin acousto-optic.
Tsarin aiki:
Haɗa raƙuman ultrasonic a cikin lu'ulu'u don samar da grating tare da canje-canje na lokaci-lokaci na refractive index.
Idan haske ya ratsa ta cikin grating, diffraction yana faruwa, kuma ƙarfin hasken da aka diffracted yana da alaƙa da ƙarfin raƙuman ultrasonic. Ta hanyar sarrafa ƙarfi ko mitar raƙuman ultrasonic, ana iya daidaita ƙarfin hasken fitarwa.

4. Mai daidaita ƙarfin lu'ulu'u na ruwa
Babban ƙa'ida: Amfani da halayyar lu'ulu'u mai ruwa-ruwa yana canza watsawar sa a ƙarƙashin filin lantarki.
Tsarin aiki:
Alkiblar daidaitawar ƙwayoyin lu'ulu'u masu ruwa-ruwa suna canzawa ƙarƙashin aikin filin lantarki, yana shafar watsa haske.
Ta hanyar amfani da ƙarfin lantarki daban-daban don sarrafa watsawar lu'ulu'u na ruwa, ana daidaita ƙarfin hasken fitarwa, wanda aka saba amfani da shi a fannonin nunawa da daukar hoto.
Nau'o'in masu daidaita ƙarfin aiki daban-daban suna da nasu halaye dangane da ƙa'idodi, aiki, da yanayin aikace-aikacen, kuma ya kamata a zaɓi nau'in da ya dace bisa ga takamaiman buƙatu.
