Ukusetshenziswa kobuchwepheshe bei-electro-optic modulator
I-modulator ye-Electro-optic（I-modulator ye-EOM） iyinto yokulawula isignali esebenzisa umphumela we-electro-optic ukulawula ukukhanya. Isimiso sayo sokusebenza ngokuvamile sifezwa ngomphumela we-Pockels (umphumela we-Pockels, okungukuthi umphumela we-Pockels), osizakala ngesimo sokuthi inkomba yokukhanya kwezinto ezibonakalayo ezingezona eziqondile iyashintsha ngaphansi kwesenzo samasimu kagesi.
Isakhiwo esiyisisekelo se-electro-optic modulator sivame ukufaka ikristalu (ikristalu lePockels) elinomphumela we-electro-optical, kanti into evamile yi-lithium niobate (LiNbO₃). I-voltage edingekayo ukuze kushintshwe isigaba ibizwa ngokuthi i-Half-wave voltage. Kumakristalu ePockels, amakhulu noma ngisho nezinkulungwane zama-volt ngokuvamile ayadingeka, yingakho kudingeka ama-amplifiers ane-voltage ephezulu. Isekethe ye-elekthronikhi efanele ingashintsha i-voltage ephezulu kangaka ngemizuzwana embalwa, okuvumela i-EOM ukuthi isetshenziswe njengeswishi esheshayo ye-optical; Ngenxa yemvelo ye-capacitive yamakristalu ePockels, laba bashayeli badinga ukuhlinzeka ngenani elikhulu lamandla kagesi (esimweni sokushintsha okusheshayo noma i-modulation, i-capacitance kufanele incishiswe ukuze kuncishiswe ukulahleka kwamandla). Kwezinye izimo, njengalapho kudingeka i-amplitude encane noma i-phase modulation, kudingeka i-voltage encane kuphela ukuze kuguqulwe. Ezinye izinto zekristalu ezingezona eziqondile ezisetshenziswa kuma-modulators e-electro-optical (I-modulator ye-EOM) zifaka i-potassium titanate (KTP), i-beta-barium borate (BBO, efanelekile ngamandla aphezulu ajwayelekile kanye/noma amaza okushintsha aphezulu), i-lithium tantalate (LiTaO3), kanye ne-ammonium phosphate (NH4H2PO4, ADP, enezakhiwo ezithile ze-electro-optical).
Ama-modulators e-Electro-optic (i-electro-optic modulator)I-modulator ye-EO） bonisa amandla abalulekile okusebenzisa emikhakheni eminingi yobuchwepheshe obuphezulu:
1. Ukuxhumana ngefayibha yokubona: Kumanethiwekhi ezokuxhumana anamuhla, ama-modulators e-electro-optical（I-modulator ye-EO） asetshenziselwa ukushintshanisa izimpawu zokukhanya, ukuqinisekisa ukudluliswa kwedatha okusebenzayo nokuthembekile emabangeni amade. Ngokulawula ngokunembile isigaba noma ubukhulu bokukhanya, ukudluliswa kolwazi ngesivinini esikhulu kanye nomthamo omkhulu kungafinyelelwa.
2. I-spectroscopy enembile: I-modulator ye-electro-optical iguqula umthombo wokukhanya ku-spectrometer ukuze ithuthukise ukunemba kokulinganisa. Ngokushintsha ngokushesha imvamisa noma isigaba sesiginali yokukhanya, ukuhlaziywa nokuhlonza izingxenye zamakhemikhali eziyinkimbinkimbi kungasekelwa, futhi isinqumo kanye nokuzwela kokulinganisa kwe-spectral kungathuthukiswa.
3. Ukucubungula idatha ye-optical esebenza kahle kakhulu: i-modulator ye-electro-optical ohlelweni lwe-optical computing kanye ne-data processing, ngokuguqulwa kwesignali ye-optical ngesikhathi sangempela ukuthuthukisa isivinini sokucubungula idatha kanye nokuguquguquka. Ngesici sokuphendula okusheshayo se-EOM, ukucubungula kanye nokudlulisa idatha ye-optical ngesivinini esiphezulu kanye nokubambezeleka okuphansi kungabonakala.
4. Ubuchwepheshe be-laser: I-electro-optic modulator ingalawula isigaba kanye nobukhulu bomsebe we-laser, inikeze ukwesekwa kokuthwebula izithombe okunembile, ukucutshungulwa kwe-laser kanye nezinye izinhlelo zokusebenza. Ngokushintsha ngokunembile amapharamitha omsebe we-laser, ukucutshungulwa kwe-laser kwekhwalithi ephezulu kungafinyelelwa.
