Electro-optical aafiaga e faasino i le aafiaga e suia le faasino igoa o se meafaitino pe a faaaoga se eletise eletise. E lua ituaiga autu o le electro-optical aafiaga, o le tasi o le aafiaga electro-optical muamua, e lauiloa foi o le aafiaga Pokels, lea e faasino i le suiga laina o mea faasino faasino ma le fanua eletise faaaogaina. O le isi o le tulaga lua electro-optical aafiaga, e lauiloa foi o le aafiaga Kerr, lea o le suiga i le faasino igoa refractive o mea e tutusa ma le sikuea o le fanua eletise. Ole tele ole fa'aogaina ole eletise e fa'avae ile aafiaga Pokels. I le faʻaaogaina o le electro-optic modulator, e mafai ona tatou faʻaogaina le vaega o le faʻalavelave faʻafuaseʻi, ma i luga o le faʻavae o le faʻaogaina o le vaega, e ala i se liua patino, e mafai foi ona tatou faʻaogaina le malosi poʻo le polarization o le malamalama.
E i ai le tele o fausaga masani eseese, e pei ona faaalia i le Ata 2. (a), (b) ma (c) o fausaga modulator tasi uma ma fausaga faigofie, ae o le lautele o le laina o le faagaioiina opitika selu e faatapulaaina e le electro-optical. bandwidth. Afai e mana'omia se selu fa'atopetope fa'atasi ma le tele o fa'auiga, e lua pe sili atu fo'i fa'atonu e mana'omia ile fa'ata, e pei ona fa'aalia ile Ata 2(d)(e). O le ituaiga mulimuli o fausaga e maua ai se selu opitika e ta'ua o le electro-optical resonator, o le electro-optical modulator e tuu i totonu o le resonator, po o le resonator lava ia e mafai ona maua ai se aafiaga eletise, e pei ona faaalia i le Ata 3.
ATA. 2 E tele masini fa'ata'ita'i mo le fa'atupuina o selu fa'avevela opitika fa'avae i lugaeletise-optic modulators

03 Electro-optic modulation optical frequency selu uiga
Fa'amanuiaga muamua: tunability
Talu ai o le puna malamalama o se leisa alaleo lautele tunable, ma o le electro-optical modulator o loʻo i ai foʻi se faʻaoga faʻapipiʻi faʻapipiʻi faʻaogaina, o le electro-optical modulation opitika faʻavave selu e mafai foi ona faʻaogaina. E le gata i le fa'alogoina o taimi, talu ai ona e fa'alogoina le fa'agasologa o galu o le modulator, e mafai fo'i ona fa'alogoina le fa'asologa o taimi o le selu fa'atosina e maua. Ose fa'amanuiaga lea e le maua e selu fa'alava fa'akomepiuta e gaosia e leisa fa'a-loka ma micro-resonators.
Itu lelei lona lua: fai soo
Ole fua ole toe fai e le gata ina fetuutuunai, ae mafai foi ona ausia e aunoa ma le suia o meafaigaluega faataitai. Ole lautele ole laina ole selu ole fa'aogaina ole electro-optic modulation e tutusa lelei ma le bandwidth modulation, o le lautele fa'atau-optic modulator bandwidth o le 40GHz, ma o le electro-optic modulation optical frequency selu toe fai taimi e mafai ona sili atu i le optic frequency selu bandwidth gaosia. i isi auala uma vagana ai le micro resonator (lea e mafai ona oʻo i le 100GHz).
Fa'amanuiaga 3: fa'ailoga mata'utia
Pe a faatusatusa i le selu opitika gaosia e isi auala, o le foliga opitika tisiki foliga o le electro-optic modulated selu opitika e fuafuaina e le tele o tikeri o le saolotoga, e pei o le leitio faailoilo, fa'aituau voltage, fa'alavelave polarization, ma isi, lea e mafai ona fa'aaogaina e pulea ai le malosi o selu eseese e ausia ai le fa'amoemoega o le fa'avasegaina.
04 Fa'aaogāina ole selu fa'avevela ole fa'aogaina ole electro-optic modulator
I le faʻaaogaina o le faʻaogaina o le electro-optic modulator optical frequency selu, e mafai ona vaevaeina i selu selu tasi ma lua. Ole va ole laina ole fusi selu e tasi e vaapiapi tele, o lea e mafai ai ona maua le sao atoatoa maualuga. I le taimi lava e tasi, pe a fa'atusatusa i le selu fa'asolosolo fa'apitoa e gaosia e ala-loka leisa, o le masini o le electro-optic modulator optical frequency selu e la'ititi ma sili atu ona fa'alogoina. O le spectrometer selu lua e gaosia e ala i le faʻalavelaveina o selu tasi e lua felagolagomaʻi ma alalaupapa faifai pea eseese, ma o le eseʻesega i le fai soo o le va o laina o le alaleo selu faʻalavelave fou. E mafai ona fa'aogaina tekinolosi selu fa'akomepiuta i fa'ata opitika, fa'asolo, fuaina o le mafiafia, fa'avasegaina o meafaigāluega, fa'atulagaina o fusi alaleo fa'asolosolo, fa'ata'ita'iga o le leitio, feso'ota'iga mamao, fa'alilo mata ma isi.
ATA. 4 Fa'ata'ita'iga o le fa'aogaina o le selu fa'avavevave: Fa'ata'ita'iga le fuaina o fa'amatalaga pulufana maualuga.
