Chowongolera cha Electro-opticndi chipangizo chofunikira kwambiri chosinthira chizindikiro cha laser chopitilira pogwiritsa ntchito deta, ma frequency a wailesi ndi ma signal a wotchi. Kapangidwe kosiyanasiyana ka modulator kali ndi ntchito zosiyanasiyana. Kudzera mu optical modulator, sikuti mphamvu ya mafunde a kuwala ingasinthidwe kokha, komanso momwe gawo ndi polarization ya mafunde a kuwala zimatha kusinthidwa. Ma electro-optic modulators omwe amagwiritsidwa ntchito kwambiri ndi Mach-Zehnderma modulator amphamvundima modulators a gawo.
TheLiNbO3 intensity modulatorimagwiritsidwa ntchito kwambiri mu makina olumikizirana othamanga kwambiri, laser sensing ndi ROF chifukwa cha magwiridwe antchito a electro-optic. Mndandanda wa R-AM wozikidwa pa kapangidwe ka MZ push-pull ndi kapangidwe ka X-cut, uli ndi mawonekedwe okhazikika a thupi ndi mankhwala, omwe angagwiritsidwe ntchito poyesa labotale komanso m'mafakitale.

Zofunikira pa chiŵerengero chachikulu cha kutha kwa zinthu
1. Woyendetsa dongosolo ayenera kukhala ndi chiŵerengero chachikulu cha kutha kwa zinthu. Khalidwe la woyendetsa dongosolo limasankha chiŵerengero chachikulu cha kutha kwa zinthu chomwe chingafikire.
2. Kugawa kwa kuwala kwa modulator kuyenera kusamalidwa. Ma modulator amakhudzidwa ndi kugawa kwa kuwala. Kugawa kwa kuwala koyenera kumatha kupititsa patsogolo kuchuluka kwa kuwala kotayika kuposa 10dB. Mu kuyesa kwa labu, nthawi zambiri chowongolera kuwala kwa kuwala chimafunika.
3. Olamulira okonda kukonda zinthu molakwika. Mu kuyesa kwathu kwa DC extinction ratio, 50.4dB extinction ratio yapezeka. Ngakhale kuti deta ya opanga ma modulator imalemba 40dB yokha. Chifukwa cha kusinthaku ndikuti ma modulator ena amasuntha mofulumira kwambiri. Olamulira a Rofea R-BC-ANY bias amasintha magetsi a bias pa sekondi imodzi iliyonse kuti atsimikizire kuti zinthuzo zachitika mwachangu.
ROF yakhala ikuyang'ana kwambiri pa ma electro-optic integrated circuits ndi zigawo zake kwa zaka khumi. Timapanga ma integrated-optical modulators ogwira ntchito bwino kwambiri ndipo timapereka mayankho ndi ntchito zatsopano kwa ofufuza asayansi ndi mainjiniya amakampani. Ma modulator a Rofea omwe ali ndi voltage yotsika komanso kutayika kochepa kwa insertion amagwiritsidwa ntchito makamaka pakugawa makiyi a quantum, machitidwe a wailesi-over-fiber, machitidwe ozindikira laser, ndi kulumikizana kwa optical kwa mbadwo wotsatira.
Timaperekanso ma modulators ambiri apadera kuti tisinthe, monga ma modulators a 1*4 array phase, ultra-low Vpi, ndi ma modulators a ultra-high extinction ratio, omwe amagwiritsidwa ntchito makamaka m'mayunivesite ndi m'masukulu. Kuphatikiza apo, timapanganso RF amplifier (modulator driver) ndi BIAS controller, photonics detector ndi zina zotero.
Mtsogolomu, tipitiliza kukonza mndandanda wazinthu zomwe zilipo, kuti tipange gulu la akatswiri aukadaulo, tipitirize kupatsa ogwiritsa ntchito zinthu zapamwamba, zodalirika, komanso zapamwamba komanso ntchito zaukadaulo.
