Kuwunika zinsinsi za kuwala: Mapulogalamu atsopano aElectro-Optic Modulator LiNbO3 gawo modulators

LiNbO3 modulatorPhase modulator ndi chinthu chofunikira kwambiri chomwe chimatha kuwongolera kusintha kwa mafunde a kuwala, ndipo chimakhala ndi gawo lalikulu pakulankhulana kwamakono ndi kuzindikira. Posachedwapa, mtundu watsopano wagawo modulatoryakopa chidwi cha ofufuza ndi mainjiniya, omwe amagwira ntchito pamafunde atatu a 780nm, 850nm ndi 1064nm, okhala ndi ma modulation bandwidths mpaka 300MHz, 10GHz, 20GHz ndi 40GHz.

Chofunika kwambiri pa gawoli modulator ndi mkulu modulation bandiwifi ndi otsika kuika kutayika. Kutayika kumatanthauza kuchepa kwamphamvu kapena mphamvu ya siginecha ya kuwala pambuyo podutsa modulita. Kutayika kwa kuika kwa gawoli modulator kumakhala kochepa kwambiri, komwe kumatsimikizira kukhulupirika kwa chizindikirocho, kotero kuti chizindikirocho chikhoza kukhalabe ndi mphamvu zambiri pambuyo posintha.

Komanso, gawo modulator ali ndi khalidwe la otsika theka-wave voteji. Theka-wave voltage ndi voteji yomwe imayenera kuyikidwa pa modulator kuti musinthe gawo la kuwala ndi madigiri a 180. Mpweya wochepa wa theka-wave umatanthauza kuti magetsi ochepa okha amafunikira kuti akwaniritse kusintha kwakukulu mu gawo la kuwala, zomwe zimachepetsa kwambiri kugwiritsa ntchito mphamvu za chipangizocho.

Pankhani ya magawo ogwiritsira ntchito, modulator yatsopanoyi imatha kugwiritsidwa ntchito kwambiri mu optical fiber sensing, optical fiber communication, kuchedwa kwa gawo (shifter), ndi kulumikizana kwachulukidwe. Mu optical fiber sensing, gawo modulator imatha kupititsa patsogolo chidwi komanso kusamvana kwa sensor. Mu kulumikizana kwa fiber optical, kumatha kupititsa patsogolo kulumikizana kwachangu komanso kutumizirana ma data. Pakuchedwa kwa gawo (kusintha), imatha kuwongolera momwe kuwala kumayendera; Pakulankhulana kwachulukidwe, itha kugwiritsidwa ntchito kuwongolera ndikuwongolera maiko a quantum.

Ponseponse, gawo latsopano modulator limatipatsa njira zowongolera bwino komanso zolondola, zomwe zimabweretsa kusintha kosinthika m'magawo ambiri. Tikuyembekeza kuti teknolojiyi ipitirire patsogolo ndikukonzekera bwino mtsogolomu, kutiululira zinsinsi zambiri za kuwala kwa ife.
