Ultra Compact IQ Modulator Bias Controller Automatic Bias Controller

Whakaahuatanga Poto:

Ko Rofea' modulator bias controller he mea hanga motuhake mo nga Mach- Zehnder modulators ki te whakarite i te mana whakahaere i roto i nga momo taiao whakahaere.I runga i tana tikanga tukatuka tohu whakarorohiko, ka taea e te kaiwhakahaere te whakarato i nga mahi tino pumau.

Ka werohia e te kaiwhakahaere he tohu reiti iti, iti te kaha tiwerawera me te ngaohiko rītaha ki roto i te modulator.Ka mau tonu te panui i te putanga mai i te modulator me te whakatau i te ahua o te ngaohiko piro me te hapa e pa ana.Ka hoatu he ngaohiko rītaha hōu i muri mai i runga i te inenga o mua.I tenei ara, ka whakarite te modulator ki te mahi i raro i te ngaohiko rītaha tika.

1. E tohu ana te MER ki te Modulator Extinction Ratio.Ko te ōwehenga mate kua tutuki ko te ōwehenga ngaro o te kaiwhakaraupapa kua tohua i roto i te papaaarangi korero.
2. Kia mahara ko te mana whatu whakaurunga kaore e rite ki te mana whatu i te waahi whiriarua kua tohua.E tohu ana ki te mana whatu morahi ka taea e te kaihurihuri te kaweake ki te kaitahuri ina awhe ngaohiko rītaha mai i −Vπ ki +Vπ .

1 Ko te Polar e whakawhirinaki ana ki te tohu RF punaha.Mena kaore he tohu RF i roto i te punaha, me pai te polar.Ka nui ake te kaha o te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino.I tenei wa, ka huri te tohu Null me te Peak point tetahi ki tetahi. Ko te tohu Q+ me te tohu-Q ka huri ano tetahi ki tetahi. Ko te huringa polar ka taea e te kaiwhakamahi te huri i te polar

tika me te kore e huri i nga tohu mahi.

2Kia kotahi anake te kowhiringa i waenga i te whakamahi photodiode kaiwhakahaere me te whakamahi photodiode modulator ranei.E taunaki ana kia whakamahia te photodiode kaiwhakahaere mo nga whakamatautau Lab mo nga take e rua.Tuatahi, kua whakapumauhia e te photodiode kaiwhakahaere nga kounga.Tuarua, he maamaa ake te whakatika i te kaha o te rama whakauru.Mehemea kei te whakamahi i te photodiode o roto o te modulator, me mohio kei te tino rite te putanga o te photodiode ki te mana whakauru.
