Ultra Compact IQ Modulator Bias Controller Automatic Bias Controller

Kufotokozera Kwachidule:

Rofea 'modulator bias controller idapangidwa mwapadera kuti ma modulators a Mach-Zehnder awonetsetse kuti magwiridwe antchito azikhala okhazikika m'malo osiyanasiyana.Kutengera njira yake yosinthira ma siginecha ya digito, wowongolera amatha kupereka magwiridwe antchito okhazikika.

Wowongolera amabaya ma frequency otsika, otsika matalikidwe dither chizindikiro pamodzi ndi kukondera voteji mu modulator.Imawerengera zomwe zimatuluka kuchokera ku modulator ndikuzindikira momwe voteji yakondera ndi zolakwika zina.Voltage yatsopano yokondera idzagwiritsidwa ntchito pambuyo pake malinga ndi muyeso wam'mbuyomu.Mwanjira iyi, modulator imatsimikiziridwa kuti ikugwira ntchito pansi pa voteji yoyenera.
