Choyamba, lingaliro loyambira la Mach Zehnder modulator

Mach-Zehnder modulator ndi makina opangira magetsi omwe amagwiritsidwa ntchito kutembenuza ma siginecha amagetsi kukhala ma siginecha owoneka bwino. Mfundo yake yogwirira ntchito imachokera ku electro-optical effect, kupyolera mu gawo lamagetsi kuti liwongolere chiwerengero cha refractive cha kuwala kwapakati kuti tikwaniritse kusintha kwa kuwala, ndikugawanitsa kuwala kolowera muzitsulo ziwiri zofanana mu nthambi ziwiri za kuwala kwa modulator.
Zida zomwe zimagwiritsidwa ntchito munthambi ziwiri zowoneka bwino ndi zida za electro-optical, zomwe refractive index zimasiyana ndi kukula kwa chizindikiro chamagetsi chogwiritsidwa ntchito kunja. Popeza kusintha kwa refractive index kwa nthambi ya optical kumapangitsa kusintha kwa gawo lazizindikiro, pomwe kumapeto kwa ma module awiri anthambi kumaphatikizidwanso, chizindikiro chophatikizika chidzakhala chizindikiro chosokoneza ndi kusintha kwamphamvu, komwe kuli kofanana ndi kutembenuka. kusintha kwa chizindikiro chamagetsi mu kusintha kwa chizindikiro cha kuwala, ndikuzindikira kusinthasintha kwa mphamvu ya kuwala. Mwachidule, modulator imatha kuzindikira kusinthika kwamagulu osiyanasiyana am'mbali powongolera voteji yake.

Chachiwiri, udindo waMach-Zehnder module

Mach-Zehnder modulator amagwiritsidwa ntchito kwambiri mukuyankhulana kwa fiberndi minda ina. Mu mauthenga a fiber optic, ma siginecha a digito amafunika kusinthidwa kukhala ma siginecha owoneka kuti atumizidwe, ndipo ma modulators a Machzender amatha kusintha ma siginecha amagetsi kukhala ma siginecha owoneka. Udindo wake ndikukwaniritsa kutumizira ma sigino othamanga kwambiri komanso apamwamba kwambiri pamakina olumikizirana optical fiber.

Mach Zehnder modulator angagwiritsidwenso ntchito pofufuza kafukufuku m'munda waoptoelectronics. Mwachitsanzo, ikhoza kugwiritsidwa ntchito kupanga magwero owunikira ogwirizana komanso kugwiritsa ntchito ma photon amodzi.

Chachitatu, mawonekedwe a Mach Zehnder modulator

1. Mach Zehnder modulator amatha kusintha zizindikiro zamagetsi kukhala zizindikiro za kuwala kuti akwaniritse kuthamanga kwapamwamba, kufalitsa kwapamwamba kwambiri.

2. Pamene modulator ikugwira ntchito, imayenera kugwiritsidwa ntchito ndi zipangizo zina monga magetsi, zowunikira kuwala, ndi zina zotero, kuti apange dongosolo lathunthu la optical fiber communication.

3. Mach Zehnder modulator ali ndi makhalidwe othamanga mofulumira komanso kugwiritsa ntchito mphamvu zochepa, zomwe zingakwaniritse zosowa za kuyankhulana kwachangu.

【Mapeto】

A Mach Zehnder modulator ndiOptical moduleamagwiritsidwa ntchito kutembenuza chizindikiro chamagetsi kukhala chizindikiro cha kuwala. Ntchito yake ndikukwaniritsa kuthamanga kwambiri, kutumizira ma siginecha apamwamba kwambiri m'malo monga optical fiber communication. Mach zender modulator ali ndi mawonekedwe oyankha mwachangu komanso kugwiritsa ntchito mphamvu pang'ono, ndipo ndi chimodzi mwazinthu zofunikira kwambiri pakupanga makina olumikizirana ndi fiber fiber.
