Fasaha aikace-aikace naelectrooptic modulator
Electro-optic modulator (EOM modulator） ɓangarorin sarrafa sigina ne wanda ke amfani da tasirin electro-optic don daidaita hasken haske. Ƙa'idar aiki ta gabaɗaya ana samun ta ta hanyar tasirin Pockels (tasirin Pockels, wato tasirin Pockels), wanda ke cin gajiyar lamarin cewa ma'anar refractive na kayan gani mara nauyi yana canzawa ƙarƙashin aikin filayen lantarki.
Asalin tsarin na'urar modulator yawanci ya haɗa da crystal (Pockels crystal) tare da tasirin electro-optical, kuma abu na yau da kullun shine lithium niobate (LiNbO₃). Wutar lantarki da ake buƙata don haifar da canjin lokaci ana kiransa wutar lantarki Half-wave. Don lu'ulu'u na Pockels, ɗaruruwa ko ma dubban volts yawanci ana buƙata, don haka buƙatar haɓakar ƙarfin lantarki. Tsarin lantarki da ya dace zai iya canza irin wannan babban ƙarfin lantarki a cikin 'yan nanoseconds, barin EOM don amfani da shi azaman mai saurin gani mai sauri; Saboda yanayin capacitive na Pockels lu'ulu'u, waɗannan direbobi suna buƙatar samar da adadi mai yawa na halin yanzu (a cikin yanayin saurin sauyawa ko daidaitawa, ya kamata a rage girman ƙarfin don rage asarar makamashi). A wasu lokuta, kamar lokacin da kawai ake buƙatar ƙaramin amplitude ko daidaita yanayin lokaci, ƙaramin ƙarfin lantarki kawai ake buƙata don daidaitawa. Sauran kayan kristal marasa kan layi da aka yi amfani da su a cikin masu daidaitawa na lantarki (electro-optical modulators)EOM modulator) sun haɗa da potassium titanate (KTP), beta-barium borate (BBO, dace da matsakaicin matsakaicin ƙarfi da / ko mafi girma juzu'i), lithium tantalate (LiTaO3), da ammonium phosphate (NH4H2PO4, ADP, tare da ƙayyadaddun kayan aikin lantarki).
Electro-optic modulators (EO modulator） nuna yuwuwar aikace-aikace mai mahimmanci a fannonin fasaha da yawa:
1. Sadarwar fiber na gani: A cikin hanyoyin sadarwar sadarwa na zamani, masu amfani da na'urorin lantarki (electro-optical modulators)EO modulator） ana amfani da su don daidaita siginar gani, suna tabbatar da ingantaccen kuma ingantaccen watsa bayanai akan nesa mai nisa. Ta daidai sarrafa lokaci ko girman haske, ana iya samun isar da watsa bayanai cikin sauri da girma.
2. Matsakaicin ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai: Electro-optical modulator yana daidaita tushen haske a cikin spectrometer don haɓaka daidaiton aunawa. Ta hanyar saurin daidaita mita ko lokaci na siginar gani, ana iya tallafawa bincike da gano abubuwan hadaddun sinadarai, kuma za'a iya inganta ƙuduri da azancin ma'aunin gani.
3. Babban aikin sarrafa bayanai na gani: electro-optical modulator a cikin na'ura mai kwakwalwa da kuma tsarin sarrafa bayanai, ta hanyar daidaitawa na lokaci-lokaci na sigina na gani don inganta saurin sarrafa bayanai da sassauci. Tare da halayen amsawa da sauri na EOM, za a iya aiwatar da sarrafa bayanai da watsawa mai sauri da ƙarancin latency.
4. Fasahar Laser: Mai amfani da wutar lantarki na lantarki zai iya sarrafa lokaci da girma na katako na laser, yana ba da tallafi don ingantaccen hoto, sarrafa laser da sauran aikace-aikace. Ta hanyar daidaita ma'auni na katako na Laser daidai, ana iya samun aikin sarrafa Laser mai inganci.
