Makhalidwe Ofunika a Chida Chosinthira Ma Electro-Optic

Kusinthasintha kwa kuwala ndi kuwonjezera chidziwitso ku mafunde a kuwala kwa chonyamulira, kotero kuti gawo linalake la mafunde a kuwala kwa chonyamulira limasintha ndi kusintha kwa chizindikiro chakunja, kuphatikizapo mphamvu ya mafunde a kuwala, gawo, ma frequency, polarization, wavelength ndi zina zotero. Mafunde a kuwala osinthidwa omwe amanyamula chidziwitsocho amatumizidwa mu ulusi, kuzindikirika ndi chowunikira chithunzi, kenako ndikuchotsa chidziwitso chofunikira.

Maziko enieni a electro-optic modulation ndi electro-optic effect, kutanthauza kuti, pansi pa mphamvu ya magetsi ogwiritsidwa ntchito, chizindikiro cha refractive cha makristalo ena chidzasintha, ndipo pamene mafunde a kuwala adutsa mu medium iyi, makhalidwe ake otumizira adzakhudzidwa ndi kusintha.

Pali mitundu yambiri ya ma electro-optic modulators (EO modulator), omwe angagawidwe m'magulu osiyanasiyana malinga ndi miyezo yosiyanasiyana.
Malinga ndi kapangidwe ka ma electrode osiyanasiyana, EOM ikhoza kugawidwa m'magulu awiri: module ya parameter yokhala ndi lumped ndi module ya mafunde oyendayenda.
Malinga ndi kapangidwe kosiyana ka ma waveguide, EOIM ikhoza kugawidwa m'magulu awiri: Msch-Zehnder interference intensity modulator ndi directional coupling intensity modulator.
Malinga ndi ubale womwe ulipo pakati pa kuwala ndi komwe magetsi akupita, EOM ikhoza kugawidwa m'magulu a longitudinal modulators ndi transverse modulators. Longitudinal electro-optic modulator ili ndi ubwino wa kapangidwe kosavuta, kugwira ntchito mokhazikika (mosasamala za polarization), kusakhala ndi birefringence yachilengedwe, ndi zina zotero. Vuto lake ndilakuti magetsi a theka la mafunde ndi okwera kwambiri, makamaka pamene ma modulation frequency ali okwera, kutayika kwa mphamvu kumakhala kwakukulu.

Electro-optical intensity modulator ndi chinthu chogwirizana kwambiri ndi Rofea chomwe chili ndi ufulu wodziyimira pawokha wa chidziwitso. Chidachi chimaphatikiza electro-optical intensity modulator, microwave amplifier ndi driving circuit yake kukhala chimodzi, chomwe sichimangothandiza ogwiritsa ntchito kugwiritsa ntchito, komanso chimawongolera kwambiri kudalirika kwa MZ intensity modulator, ndipo chingapereke ntchito zomwe zasinthidwa malinga ndi zosowa za ogwiritsa ntchito.

Mbali:
⚫ Kutayika kochepa kwa malo olowera

⚫ Bandwidth yogwira ntchito kwambiri

⚫ Malo ogwirira ntchito osinthika komanso osinthika

⚫ AC 220V

⚫ Yosavuta kugwiritsa ntchito, gwero la kuwala losankha

Ntchito:
⚫Kachitidwe ka kusintha kwa liwiro lakunja
⚫Kuphunzitsa ndi njira yowonetsera yoyesera
⚫Chopangira chizindikiro cha kuwala
⚫Optical RZ, dongosolo la NRZ
