Rof Bias Point Controller kōwae mana rītaha aunoa o lithium niobate MZ modulator

Whakaahuatanga Poto:

ROF-Ko te raupapa ABC-MZ ka whakamahia te waahanga mana whakahaere aunoa mo te mana whakahaere aunoa o te lithium niobate MZ modulator, ka taea e te modulator te mahi i te waahi iti rawa, te waahi teitei, te waahi orthogonal ranei (rohe raina). Kei te whakauru ano te kōwae ki te 1/99 coupler, ka taea te whakahaere i te whakawhiti i te waahi mahi ma te tauranga rangatū o waho, me te tautoko i te aratau whakatikatika a-ringa, e pai ana mo nga momo rereke rereke rereke me nga tono, a he tino pai mo te taiwhanga whare wananga ki te hanga i nga whakamatautau papamahi.

Tuhipoka:

Ko te 1* e tohu ana ki te whakaurunga awhe mana ki te kōwae i te wa e tino nui ana te putanga modulator. Mo te iti o te mana whakahaere o te modulator me te nui o te matemate, me tika te whakanui ake i te mana whakauru; Ma nga whakaritenga whakauru mana motuhake, ka taea e koe te whakatika i nga tohu taapiri a-roto me nga tohu whiwhinga, tirohia koa nga hoko ina tuku ota.

2* A, no te whakatakoto i tetahi ota, tohua koa te roangaru mahi, e tika ana kia arotauhia kia rite ki te roangaru mahi.

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.
