Eo modulatorFa'asologa: Saosaoa maualuga, maualalo voltage, la'ititi lithium niobate ata tifaga masini pulea polarization
O galu malamalama i avanoa avanoa (faʻapea foʻi ma galu electromagnetic o isi alalaupapa) o galu faʻafefe, ma o le itu o le vibration o lona eletise ma le mageta o loʻo i ai ni faʻatonuga eseese i le koluse faʻasaga i le itu o le faʻasalalauga, o le mea lea o le polarization. o le malamalama. O le polarization e taua tele le fa'aogaina i le matā'upu o feso'ota'iga mata'utia, su'esu'ega fa'apisinisi, biomedicine, fa'alogoina mamao o le lalolagi, militeri fa'aonaponei, va'alele ma le vasa.
I le natura, ina ia sili atu le faʻatautaia, o le tele o meaola ua faʻatupuina faiga faʻaaliga e mafai ona iloagofie ai le polarization o le malamalama. Mo se faʻataʻitaʻiga, o pi e lima mata (tolu mata tasi, lua mata tuʻufaʻatasia), o ia mea e aofia ai mata laiti e 6,300, lea e fesoasoani i pi e maua ai se faʻafanua o le polarization o le malamalama i itu uma i le lagi. E mafai e le lagomeli ona fa'aoga le fa'afanua fa'apipi'i e su'e ma ta'ita'i sa'o ana lava ituaiga i fuga na te mauaina. E leai ni totoga faʻaletino a tagata soifua e pei o pi e lagona ai le polarization o le malamalama, ma e manaʻomia le faʻaogaina o meafaigaluega faʻapitoa e lagona ma faʻaogaina le polarization o le malamalama. O se faʻataʻitaʻiga masani o le faʻaogaina o mata tioata polarizing e faʻatonu ai le malamalama mai ata eseese i le agavale ma le taumatau mata i polarizations perpendicular, o le mataupu faavae o ata tifaga 3D i le fale tifaga.
O le atinaʻeina o masini faʻatonutonu polarization mataʻutia maualuga o le ki lea e atiaʻe ai tekinolosi faʻaogaina malamalama polarized. O masini fa'apolokalame masani e aofia ai le fa'atupuina o le setete, scrambler, polarization analyzer, polarization controller, ma isi. I tausaga talu ai nei, o le optical polarization manipulation technology o loʻo faʻavaveina le alualu i luma ma loloto le tuʻufaʻatasia i le tele o vaega o loʻo tulaʻi mai e taua tele.
Aveinafesootaiga opitikae fai ma faʻataʻitaʻiga, faʻamalosia e le manaʻoga mo le tele o faʻasalalauga faʻamatalaga i nofoaga autu o faʻamaumauga, mamao mamao vavalalataopitikatekinolosi feso'ota'iga o lo'o faasolosolo malie ona sosolo atu i feso'ota'iga feso'ota'iga pupu'u e matua maaleale i le tau ma le fa'aaogaina o le malosi, ma o le fa'aogaina o tekinolosi fa'aogaina polarization e mafai ona fa'aitiitia lelei ai le tau ma le fa'aogaina o le eletise o feso'ota'iga feso'ota'iga vavalalata pupuu. Ae ui i lea, i le taimi nei, o le puleaina o le polarization e masani lava ona iloa e vaega faʻapitoa faʻapitoa, lea e matua faʻatapulaaina ai le faʻaleleia o le faʻatinoga ma le faʻaitiitia o tau. Faatasi ai ma le televave o le atinaʻeina o tekonolosi tuʻufaʻatasiga optoelectronic, tuʻufaʻatasiga ma pu o ni faiga taua i le lumanaʻi atinaʻe o masini faʻatonutonu polarization.
Ae ui i lea, o taʻiala faʻafefeteina ua saunia i tioata masani lithium niobate o loʻo i ai le le lelei o le faʻatusatusaina o faʻailoga faʻasolosolo laiti ma vaivai le malosi o le fusifusia. I le tasi itu, o le tele o le masini e tele, ma e faigata ona faʻafetaui manaʻoga atinaʻe o le tuʻufaʻatasia. I le isi itu, o le fesoʻotaʻiga electrooptical e vaivai, ma o le eletise avetaʻavale o le masini e maualuga.
I tausaga talu ai nei,masini atafaʻavae i luga ole lithium niobate mea ata tifaga manifinifi ua faia le alualu i luma faʻasolopito, ausia maualuga maualuga ma maualalo le taʻavale voltage nai lo masani.lithium niobate masini photonic, o lea e fiafia i latou e le alamanuia. I suʻesuʻega talu ai nei, o loʻo faʻaalia le puʻupuʻu faʻapipiʻi faʻapipiʻiina i luga o le lithium niobate thin film photonic integration platform, e aofia ai polarization generator, scrambler, polarization analyzer, polarization controller ma isi galuega autu. O vaega autu o nei tupe meataalo, e pei o le saoasaoa o le gaosiga o le polarization, fua faatatau o le faʻaumatiaina o le polarization, le saoasaoa o le faʻalavelave faʻafuaseʻi, ma le saoasaoa o fua, ua setiina faamaumauga fou o le lalolagi, ma ua faʻaalia le lelei tele o le saoasaoa, taugofie, leai se parasitic modulation gau, ma maualalo. eletise eletise. O fa'ai'uga o su'esu'ega mo le taimi muamua e iloa ai se fa'asologa o fa'atinoga maualugalithium niobateata manifinifi masini e pulea polarization mata, lea e aofia ai iunite faavae e lua: 1. Polarization rotation/splitter, 2. Mach-zindel interferometer (faamatalaga >), e pei ona faaalia i le Ata 1.
