Ultra Compact IQ Modulator Bias Controller Automatic Bias Controller

Tlhaloso e Khutšoanyane:

Rofea 'modulator bias controller e etselitsoe ka ho khetheha li-modulator tsa Mach-Zehnder ho netefatsa boemo bo tsitsitseng ba ts'ebetso libakeng tse fapaneng tsa ts'ebetso.Ho ipapisitsoe le mokhoa oa eona oa ts'ebetso ea mats'oao a digitized ka botlalo, molaoli a ka fana ka ts'ebetso e tsitsitseng haholo.

Molaoli o kenya lets'oao le tlase, lets'oao le tlase la amplitude dither hammoho le voltage ea bias ho modulator.E lula e bala tlhahiso ho tsoa ho modulator mme e khetha boemo ba voltage ea bias le phoso e amanang le eona.Ho tla sebelisoa lentsoe le lecha la bias voltage ho latela tekanyo e fetileng.Ka tsela ena, modulator e netefatsoa hore e sebetsa tlas'a voltage e nepahetseng ea bias.
