Ultra Compact IQ Modulator Bias Controller Tsis Siv Neeg Bias Controller

Lus piav qhia luv luv:

Rofea 'modulator bias maub los tshwj xeeb yog tsim los rau Mach- Zehnder modulators los xyuas kom meej lub xeev ua haujlwm ruaj khov hauv ntau qhov chaw ua haujlwm.Raws li nws txoj kev ua tiav digitized teeb liab, tus maub los tuaj yeem muab kev ua haujlwm ruaj khov.

Tus maub los txhaj qhov tsawg zaus, tsis tshua muaj amplitude dither teeb liab ua ke nrog kev tsis ncaj ncees voltage rau hauv lub modulator.Nws tseem nyeem cov lus tso tawm los ntawm lub modulator thiab txiav txim siab qhov xwm txheej ntawm qhov tsis sib haum xeeb thiab qhov cuam tshuam txog qhov yuam kev.Ib qho kev tsis txaus ntseeg tshiab yuav raug siv tom qab cov lus raws li kev ntsuas yav dhau los.Nyob rau hauv txoj kev no, lub modulator yog ua kom ntseeg tau tias ua haujlwm nyob rau hauv qhov tsis zoo voltage.
