1. MER e faasino ile Modulator Extinction Ratio.O le fua fa'atatau ua ausia e masani lava o le fua fa'atatau o le modulator ua fa'amaoti mai i le fa'amaumauga o le modulator.
2. Fa'amolemole ia maitauina e le fetaui le mana fa'apipi'i ma le mana fa'aituau i le tulaga fa'aitu ua filifilia.O lo'o fa'asino i le maualuga o le malosi fa'apitoa e mafai e le modulator ona fa'atau atu i le pule pe a fa'aituau le voluma mai le −Vπ i le +Vπ .

1 Polar e fa'alagolago ile fa'ailoga RF system.Afai e leai se faʻailoga RF i le faiga, e tatau ona lelei le polar.A faʻaalia le faʻailoga RF e sili atu nai lo se tulaga, o le polar o le a suia mai le lelei i le leaga.I le taimi nei, o le Null point ma le Peak point o le a fesuiai le tasi i le isi. Q + point ma Q-point o le a fesuiai le tasi ma le isi. Polar switch e mafai ai e le tagata ona suia le polar
tuusao e aunoa ma le suia o vaega o galuega.
2Na'o le tasi le filifiliga e tatau ona filifilia i le va o le fa'aogaina o le photodiode pule po'o le fa'aogaina o le photodiode modulator.E fautuaina le fa'aogaina o le photodiode e pulea mo su'esu'ega a le Lab mo mafuaaga e lua.Muamua, o le pule o le photodiode ua faʻamautinoa uiga lelei.Lona lua, e sili atu ona faigofie le fetuutuunai o le malamalama i totonu intensity.If faʻaaogaina le photodiode totonu o le modulator, faamolemole ia mautinoa o le gaosiga o loʻo i ai nei o le photodiode e matua faʻatusatusa i le mana faʻaoga.
