I-Ultra Compact DP-IQ Modulator Bias Controller Umlawuli we-Bias ozenzekelayo

Inkcazelo emfutshane:

I-Rofea 'modulator bias controller yenzelwe ngokukodwa iimodyuli ze-Mach-Zehnder ukuze kuqinisekiswe imeko yokusebenza ezinzileyo kwiindawo ezahlukeneyo zokusebenza. Ngokusekwe kwindlela yayo yokusetyenzwa kwedijithali ngokupheleleyo, umlawuli unokubonelela ngentsebenzo ezinzileyo.

Umlawuli ufaka i-frequency ephantsi, i-amplitude ephantsi ye-dither signal kunye ne-bias voltage kwimodyuli. Ihlala ifunda imveliso evela kwimodyuli kwaye imisela imeko yombane we-bias kunye nempazamo ehambelana nayo. Ivoltheji entsha ye-bias iya kusetyenziswa emva kwamagama ngokomlinganiselo wangaphambili. Ngale ndlela, imodyuli iyaqinisekiswa ukuba isebenza phantsi kombane ofanelekileyo wokuthamba.

1 Ipolar ixhomekeke kwisignali ye-RF yesixokelelwano. Xa kungekho mqondiso weRF kwisixokelelwano, i-polar kufuneka ibe ntle. Xa isignali yeRF ine-amplitude enkulu kunomgangatho othile, i-polar iya kutshintsha ukusuka ku-positive ukuya ku-negative. Ngeli xesha, iNull point kunye nePeak point ziya kutshintshana. Inqaku le-Q + kunye ne-Q-inqaku liya kutshintsha kunye nomnye. Ukutshintsha kwePolar kwenza umsebenzisi atshintshe

polar ngqo ngaphandle kokutshintsha iindawo zokusebenza.

1 Inye kuphela ukhetho oluya kunyulwa phakathi kokusebenzisa isilawuli sefotodiode okanye ukusebenzisa imodyuli yefotodiode. Kuyacetyiswa ukuba usebenzise isilawuli sefotodiode kwimifuniselo yeLab ngezizathu ezibini. Okokuqala, isilawuli se-photodiode siqinisekise iimpawu. Okwesibini, kulula ukuhlengahlengisa ukukhanya kwegalelo. Ukuba usebenzisa ifotodiode yemodyuli yangaphakathi, nceda uqiniseke ukuba imveliso yangoku yefotodiode ilingana ngokungqongqo namandla egalelo.
