Amfani da fasaha nana'urar sarrafa na'urar lantarki (electro-optical modulator)

Na'urar daidaita hasken lantarki (Electro-optic modulator)Mai daidaita EOM） wani sinadari ne na sarrafa sigina wanda ke amfani da tasirin electro-optic don daidaita hasken haske. Ana samun ka'idar aikinsa gabaɗaya ta hanyar tasirin Pockels (tasirin Pockels, wato tasirin Pockels), wanda ke amfani da abin da ke faruwa cewa ma'aunin haske na kayan gani marasa layi yana canzawa ƙarƙashin aikin filayen lantarki.

Tsarin asali na na'urar lantarki mai amfani da wutar lantarki yawanci ya haɗa da lu'ulu'u (Pockels crystal) tare da tasirin electro-optical, kuma kayan da aka saba amfani da su shine lithium niobate (LiNbO₃). Ana kiran wutar lantarki da ake buƙata don haifar da canjin lokaci ƙarfin lantarki na Half-wave. Ga lu'ulu'u na Pockels, ana buƙatar ɗaruruwa ko ma dubban volts, don haka buƙatar amplifiers masu ƙarfi.

A wasu lokuta, kamar lokacin da ake buƙatar ƙaramin girma ko daidaitawar lokaci kawai, ƙaramin ƙarfin lantarki ne kawai ake buƙata don daidaitawa. Sauran kayan lu'ulu'u marasa layi waɗanda ake amfani da su a cikin na'urorin lantarki masu amfani da wutar lantarki (Mai daidaita EOM) sun haɗa da potassium titanate (KTP), beta-barium borate (BBO, wanda ya dace da matsakaicin ƙarfi da/ko mafi girman mitoci na sauyawa), lithium tantalate (LiTaO3), da ammonium phosphate (NH4H2PO4, ADP, tare da takamaiman kaddarorin electro-optical).

Masu daidaita na'urorin lantarki (Electro-optical modulators)EO modulator） yana nuna mahimmancin damar amfani a fannoni daban-daban na fasaha:

1. Sadarwar fiber na gani: A cikin hanyoyin sadarwa na zamani, masu daidaita wutar lantarki (electro-optical modulators)EO modulatorAna amfani da su don daidaita siginar gani, tabbatar da ingantaccen watsa bayanai a cikin nisa mai nisa. Ta hanyar sarrafa matakin haske ko girman haske daidai, ana iya cimma watsa bayanai mai sauri da babban iko.

2. Daidaito na gani: Na'urar auna haske ta lantarki (electro-optical modulator) tana daidaita tushen haske a cikin na'urar auna haske don inganta daidaiton aunawa.
