Electro-optic modulatoro le masini autu lea e fa'aogaina ai le fa'ailo leisa faifaipea e fa'aoga ai fa'amaumauga, alaleo leitio ma fa'ailoga uati.O fausaga eseese o le modulator e eseese galuega.E ala i le modulator opitika, e le gata e mafai ona suia le malosi o le galu malamalama, ae o le vaega ma le tulaga polarization o le galu malamalama e mafai ona suia.Ole fa'aogaina ole electro-optic modulators ole Mach-Zehndermalosi modulatorsmavaega modulators.
O leLiNbO3 malosi modulatoro lo'o fa'aaogaina lautele i faiga fa'afeso'ota'i fa'akomepiuta maualuga, fa'alogoina leisa ma faiga ROF ona o le lelei o le fa'aogaina o le eletise.O le R-AM faʻavae e faʻavae i luga o le MZ push-pull structure ma le X-cut design, o loʻo i ai uiga faʻaletino ma vailaʻau, e mafai ona faʻaaogaina uma i suʻesuʻega falesuesue ma faiga faʻapisinisi.

Manaoga mo le maualuga o le faʻaumatia
1. System modulator e tatau ona i ai le maualuga o le faʻaumatia.O uiga o le system modulator e filifili ai le maualuga o le fa'aumatiaga fua faatatau e mafai ona ausia.
2. E tatau ona tausia lelei le Polarization o le moli faʻapipiʻiina.Modulators e maaleale i polarization.O le polarization talafeagai e mafai ona faʻaleleia le fua faʻaumatia ile 10dB.I su'esu'ega a le fale su'esu'e, e masani lava e mana'omia se pule fa'apolokalame.
3. Pulea fa'aituau sa'o.I la matou fa'ata'ita'iga fa'atatau DC fa'aumatia, 50.4dB fua fa'atatau ua ausia.A'o fa'amaumauga a le fa'aogaina o le modulator na'o lisi 40dB.O le mafuaʻaga o lenei faʻaleleia o nisi o modulators e tafe tele vave.Rofea R-BC-SOSE pule fa'aituau fa'afou le voltage fa'aituau i le 1 sekone e fa'amautinoa ai le tali vave.
O lo'o taula'i le ROF i ta'amilosaga feso'ota'i eletise-optic ma vaega mo le sefulu tausaga.Matou te gaosia mea faʻapipiʻi faʻapipiʻi-optical modulators maualuga ma tuʻuina atu fofo fou ma auaunaga mo tagata suʻesuʻe faasaienisi ma inisinia alamanuia.O le fa'aogaina o le Rofea e maualalo le eletise ma maualalo le fa'aofiina gau sa fa'aaoga muamua i le tufatufaina o ki quantum, fa'aeletise-over-fiber system, masini fa'alogo leisa, ma feso'ota'iga mata'imata o lo'o sosoo mai.
Matou te tuʻuina atu foʻi le tele o modulators faʻapitoa mo faʻasalalauga, e pei o le 1 * 4 array phase modulators, ultra-low Vpi, ma le ultra-high extinction ratio modulators, faʻaaoga muamua i iunivesite ma inisitituti.E le gata i lea, matou te gaosia foi le RF amplifier (modulator driver) ma le BIAS controller, photonics detector etc.
I le lumanaʻi, o le a faʻaauau pea ona faʻaleleia le faʻasologa o oloa o loʻo i ai nei, e fausia ai se 'au faʻapitoa faʻapolofesa, faʻaauau pea ona tuʻuina atu i tagata faʻaoga le tulaga maualuga, faʻatuatuaina, oloa maualuga ma auaunaga faʻapitoa.
