Niki Moderi-Zehnder Modulator

UwitekaImashini ya Zehnder(MZ Modulator) nigikoresho cyingenzi cyo guhindura ibimenyetso bya optique bishingiye kumahame yo kwivanga. Ihame ryakazi ryayo nuburyo bukurikira: Ku ishami rya Y-shusho ku musozo winjiza, urumuri rwinjira rugabanyijemo imirongo ibiri yumucyo kandi rwinjira muburyo bubiri bwa optique bwo kohereza. Umuyoboro wa optique ugizwe nibikoresho bya electro-optique. Mugukoresha imbaraga zayo zifotora, mugihe ibimenyetso byamashanyarazi byakoreshejwe hanze bihinduka, indangagaciro yo kwangirika yibikoresho byayo irashobora guhinduka, bikavamo itandukaniro ryinzira zitandukanye za optique hagati yibiti byombi byumucyo bigera kumashami Y ishusho kumasoko asohoka. Iyo ibimenyetso bya optique mumiyoboro ibiri ya optique bigera kuri Y-ishami ryumusozo urangiye, guhuza bizaba. Bitewe no gutinda kwicyiciro cyibimenyetso bibiri bya optique, kwivanga bibaho hagati yabo, guhindura amakuru yo gutandukanya icyiciro gitwarwa nibimenyetso bibiri bya optique mubisobanuro byimbaraga zamakuru asohoka. Kubwibyo, umurimo wo guhindura ibimenyetso byamashanyarazi kubitwara optique urashobora kugerwaho mugucunga ibipimo bitandukanye bya voltage yumuriro wa moderi ya Werurwe-Zehnder.

Ibipimo fatizo byaMZ Modulator

Ibipimo fatizo bya MZ Modulator bigira ingaruka kumikorere ya modulator muburyo butandukanye bwo gusaba. Muri byo, ibipimo byingenzi bya optique nibipimo byamashanyarazi nibi bikurikira.

Ibipimo byiza:

(1) Umuyoboro mwiza wa optique (3db umurongo) Umuyoboro wa optique werekana inshuro zerekana ibimenyetso mugihe modulator ikora mubisanzwe kandi ni ibipimo byo gupima amakuru atwara ubushobozi bwikigo cya optique muriamashanyarazi ya optique.

. Ikigereranyo cyo kuzimangana nikintu cyo gusuzuma amashanyarazi ya optique ya moderi.

(3) Garuka igihombo: Ikigereranyo cyumucyo wagaragajwe kumpera yinjiza yamodulatorKuri kwinjiza urumuri imbaraga, hamwe nigice cya dB. Gutakaza igihombo nikintu cyerekana imbaraga zibyabaye zigaruka kumasoko yikimenyetso.

. Igihombo cyo gushiramo nikimenyetso gipima gutakaza ingufu za optique ziterwa no kwinjiza inzira nziza.

Ibipimo by'amashanyarazi:

Igice cya kabiri cyumuvuduko: Bivuga itandukaniro rya voltage isabwa kugirango voltage yo gutwara ihindure modulator kuva kuri reta ijya kuri leta. Ibisohoka optique ya MZM Modulator iratandukanye ubudahinduka hamwe nimpinduka ya bias voltage. Iyo modulator isohora ibyiciro bya dogere 180 itandukanyirizo, itandukaniro ryumubyigano wa bias uhuye ningingo ntoya yegeranye kandi ingingo ntarengwa ni igice cya kabiri cyumubyigano, hamwe nigice cya V. Iyi parameter igenwa nibintu nkibintu, imiterere nibikorwa, kandi ni ikintu cyihariye cyaMZM Modulator.

. Igice ni V. DC bias bias ikoreshwa mugucunga kubogama kwa modulator kugirango byuzuze ibisabwa bitandukanye.

. Igice ni V. Ikimenyetso cya radiyo ni ikimenyetso cyamashanyarazi kigomba guhindurwa kuri optique.
