Rof Electro-optic modulator 850 nm electro optic intensity modulator 10G

Kufotokozera Kwachidule:

ROF-AM 850nm lithium niobate optical intensity modulator imagwiritsa ntchito njira yotsogola yosinthira ma proton, yomwe ili ndi kutayika kochepa kwa insertion, bandwidth yayikulu yosinthira, voltage yotsika ya theka la mafunde, ndi zina, zomwe zimagwiritsidwa ntchito makamaka pa dongosolo lolumikizirana la space optical, cesium atomic time base, zida zopangira ma pulse, quantum optics, ndi zina.
Imagwiritsa ntchito njira yosinthira ma proton yapamwamba, yomwe ili ndi kutayika kochepa kwa ma insertion, bandwidth yayikulu yosinthira, voltage yotsika ya theka la mafunde, ndi zina, zomwe zimagwiritsidwa ntchito makamaka pa dongosolo lolumikizirana la space optical, cesium atomic time base, zida zopangira ma pulse, quantum optics, ndi zina.

Chiŵerengero cha kutha kwa Maxim DC

Mu kuyesera uku, palibe zizindikiro za RF zomwe zinagwiritsidwa ntchito pa dongosololi. Pure DC extinciton yayesedwa.
1. Chithunzi 5 chikuwonetsa mphamvu yowunikira ya kutulutsa kwa modulator, pamene modulator ikulamulidwa pa Peak point. Chikuwonetsa 3.71dBm pachithunzichi.
2. Chithunzi 6 chikuwonetsa mphamvu ya kuwala ya kutulutsa kwa modulator, pamene modulator ikulamulidwa pa Null point. Ikuwonetsa -46.73dBm pachithunzichi. Mu kuyesa kwenikweni, mtengo umasiyana pafupifupi -47dBm; ndipo -46.73 ndi mtengo wokhazikika.
3. Chifukwa chake, chiŵerengero cha DC extinction chokhazikika chomwe chinayesedwa ndi 50.4dB.

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.
