I-Ultra Compact IQ Modulator Bias Controller Isilawuli Esizenzakalelayo Sokuchema

Incazelo emfushane:

I-Rofea' modulator bias controller yakhelwe ngokukhethekile amamoduli e-Mach-Zehnder ukuze aqinisekise isimo sokusebenza esizinzile ezindaweni ezihlukahlukene zokusebenza.Ngokusekelwe endleleni yayo yokucubungula isignali yedijithali ngokugcwele, isilawuli singanikeza ukusebenza okuzinzile kakhulu.

Isilawuli sifaka imvamisa ephansi, isignali ye-amplitude ephansi ye-dither kanye ne-bias voltage kumoduli.Ilokhu ifunda okukhiphayo kumoduli futhi inquma isimo se-voltage echema kanye nephutha elihlobene.I-voltage entsha yokuchema izosetshenziswa amagama angemuva ngokwesilinganiso sangaphambilini.Ngale ndlela, i-modulator iqinisekiswa ukuthi isebenza ngaphansi kwe-voltage efanele yokuchema.

1. I-MER ibhekisela ku-Modulator Extinction Ratio.Isilinganiso sokuqothulwa esifinyelelwe ngokuvamile siyisilinganiso sokushabalala semoduli esicaciswe kudatha yemoduli.
2. Sicela uqaphele ukuthi amandla okukhanya okufaka awahambisani namandla okubona endaweni ekhethiwe yokuchema.Isho umkhawulo wamandla okubona imodulator engawathumela kusilawuli lapho i-voltage echema isuka ku-−Vπ iye ku-+Vπ .

1 I-Polar incike esignali yesistimu ye-RF.Uma ingekho isignali ye-RF ohlelweni, i-polar kufanele ibe iphozithivu.Uma isignali ye-RF ine-amplitude enkulu kuneleveli ethile, i-polar izoshintsha isuke ekubeni iphozithivu iye kwenegethivu.Ngalesi sikhathi, i-Null point kanye ne-Peak point zizoshintshana.Iphoyinti le-Q+ nephoyinti le-Q zizoshintshana futhi.Iswishi ye-Polar yenza umsebenzisi akwazi ukushintsha indawo epholile.

ngqo ngaphandle kokushintsha izindawo zokusebenza.

2Inketho eyodwa kuphela ezokhethwa phakathi kokusebenzisa i-photodiode yesilawuli noma ukusebenzisa i-modulator photodiode.Kunconywa ukusebenzisa i-photodiode yesilawuli ekuhlolweni kweLab ngezizathu ezimbili.Okokuqala, i-photodiode yesilawuli inezimfanelo eziqinisekisiwe.Okwesibili, kulula ukulungisa ukukhanya kokufakwayo.Uma usebenzisa i-photodiode yangaphakathi yemoduli, sicela wenze isiqiniseko sokuthi ukuphuma kwe-photodiode kuhambisana ngokuqinile namandla okufaka.
