I-Ultra Compact 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. I-MER ibhekisa kwi-Modulator Extinction Ratio.Umlinganiselo wokutshabalala ophunyeziweyo uqhelekile ngumlinganiselo wokuphela kwemodyuli echazwe kwidatha yemodyuli.
2. Nceda uqaphele ukuba i-input optical power ayihambelani namandla okukhanya kwindawo ekhethiweyo ye-bias point.Ibhekisa kumandla okukhanya aphezulu anokuthi imodyuli iwathumele kwisilawuli xa amandla ombane acalanye asuka ku- −Vπ ukuya ku +Vπ.

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, i-Null point kunye ne-Peak point iya kutshintsha kunye nomnye.Inqaku le-Q + kunye ne-Q-point iya kutshintshela kunye.

ngqo ngaphandle kokutshintsha iindawo zokusebenza.

2Inye 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 ukunyenyisa igalelo ukukhanya intensity.Ukuba usebenzisa imodyuli yangaphakathi photodiode, nceda uqinisekise ukuba imveliso yangoku ye photodiode ngokungqongqo ngokomlinganiselo amandla igalelo.
