Nau'in da aka saba amfani da shina'urar ƙara ƙarfin ganiana amfani da shi a fannin sadarwa ta gani (optical communication)

Idan aka watsa siginar gani a cikin zaruruwan gani, yayin da nisan ke ƙaruwa, siginar gani za ta yi rauni a hankali har ma ta haifar da katsewar sadarwa… Har sai bayyanar amplifiers na gani, suna kama da “tashar mai”, suna sake cika kuzarin siginar gani ta yadda za su iya ɗaukar bayanai zuwa inda za su je cikin sauƙi. Wannan batu zai gabatar muku da wani amplifier na gani da aka saba amfani da shi a cikin sadarwa ta gani -amplifier fiber mai amfani da erbium(Amplifier na gani na EDFA).

Ana haɗa wani abu mai ƙara girman zare mai erbium, kamar yadda sunan ya nuna: Erbium (Er), wani abu mai ƙarancin ƙarfi na ƙasa, cikin zaren quartz. Lokacin da siginar gani ta shiga ta cikin zaren mai erbium, ions ɗin erbium na trivalent (Er³⁺) za su sha ƙarfin hasken famfo kuma su canza zuwa matakin makamashi mafi girma. Adadin ƙwayoyin da ke cikin yanayin da aka motsa suna fuskantar juyawa.

A halin yanzu, masu bincike suna haɓaka amplifiers na fiber mai girman dual-band (DBFA) da amplifiers na ultra-wideband (UWOA), da nufin faɗaɗa gain bandwidth zuwa ga dukkan wavelength division multiplexing (WDM) mitar band. Kwanan nan, ƙungiyar bincike ta haɗin gwiwa daga cibiyoyin bincike na Turai ta ƙirƙiro amplifier na traveling wave parametric amplifer bisa ga photonic chips. Ta hanyar ƙaramin tsari, yana cimma ultra-wideband sigina amplification, tare da bandwidth na 140 nm (sau uku fiye da na gargajiya EDFA), kuma an rage girman zuwa matakin santimita, yana ba da tallafi mai sauri ga cibiyoyin bayanai da lissafin AI. Waɗannan "super amplifiers" za su tallafawa watsawa na tsawon rai sama da ɗari a kowace fiber, suna shimfida harsashin sadarwa na holographic da masana'antu masu hankali da sauran aikace-aikace a zamanin 6G.
