Kutloisiso e felletseng ea li-electro-optic modulators
Modulator ea elektro-optic (EOM) ke mochine oa motlakase oa motlakase o sebelisang matšoao a motlakase ho laola matšoao a optical, haholo-holo a sebelisoang ts'ebetsong ea phetoho ea optical sebakeng sa thekenoloji ea thekenoloji ea puisano.
E latelang ke kenyelletso e qaqileng ea modulator ea electro-optic:
1. Molao-motheo oa motheo oamochine oa motlakase oa motlakasee itšetlehile ka phello ea electro-optic, ke hore, index ea refractive ea lisebelisoa tse ling e tla fetoha tlas'a ketso ea tšimo ea motlakase e sebelisitsoeng. Ha maqhubu a khanya a feta har'a likristale tsena, litšoaneleho tsa phatlalatso li fetoha le sebaka sa motlakase. Ho sebelisa molao-motheo ona, mohato, amplitude kapa polarization boemo baya mahlopontšo e ka laoloa ka ho fetola sebaka sa motlakase se sebelisoang.
2. Sebopeho le sebopeho Li-modulators tsa Electro-optical hangata li entsoe ka litsela tsa optical, amplifiers, filters le photoelectric converters. Ho phaella moo, e kenyelletsa likarolo tsa bohlokoa tse kang bakhanni ba lebelo le phahameng, li-fiber tsa optical le likristale tsa piezoelectric. Sebopeho sa electro-optic modulator se ka fapana ho ea ka mokhoa oa sona oa ho feto-fetoha le litlhoko tsa kopo, empa hangata se kenyelletsa likarolo tse peli: electro-optic inverter module le photoelectric modulation module.
3. Mokhoa oa ho feto-fetoha oa motlakase Electro-optic modulator e na le mekhoa e 'meli ea mantlha ea ho feto-fetoha:ho feto-fetoha ha maemole ho feto-fetoha ha matla. Phase modulation: Karolo ea sepalangoang e fetoha ha lets'oao le fetotsoeng le fetoha. Ho Pockels electro-optic modulator, leseli la carrier-frequency le feta ka kristale ea piezoelectric, 'me ha motlakase o fetotsoeng o sebelisoa, sebaka sa motlakase se hlahisoa ka kristale ea piezoelectric, e leng se etsang hore index ea eona ea refractive e fetohe, kahoo e fetola karolo ea leseli. .Ho feto-fetoha ha matla: Matla (matla a khanya) a mochine oa optical a fetoha ha lets'oao le fetotsoeng le fetoha. Ho feto-fetoha ha matla hangata ho finyelloa ho sebelisoa Mach-Zehnder intensity modulator, e lekanang ka molao le interferometer ea Mach-Zehnder. Ka mor'a hore maballo a mabeli a fetoloe ke letsoho le fetohang la mohato ka matla a fapaneng, qetellong a kena-kenana le ho fumana lets'oao la optical modulated intensity.
4. Libaka tsa ts'ebeliso Li-modulators tsa Electro-optical li na le mefuta e mengata ea lits'ebetso likarolong tse 'maloa, ho kenyeletsoa empa li sa felle feela ho: puisano ea optical: Litsamaisong tse phahameng tsa puisano tsa optical, li-electro-optical modulators li sebelisoa ho fetolela lipontšo tsa elektroniki hore e be lipontšo tsa optical. ho fihlella khouto ya data le phetiso. Ka ho fetola matla kapa mohato oa lets'oao la optical, mesebetsi ea ho fetoha ha leseli, taolo ea sekhahla sa ho feto-fetoha le ho feto-fetoha ha lets'oao e ka phethahala. Spectroscopy: Li-modulators tsa electro-optical li ka sebelisoa e le likarolo tsa lisebelisoa tsa optical spectrum analyzers bakeng sa tlhahlobo ea spectral le tekanyo. Tekanyo ea tekheniki: li-electro-optical modulators le tsona li bapala karolo ea bohlokoa lits'ebetsong tsa radar, tlhahlobo ea bongaka le likarolo tse ling. Mohlala, lits'ebetsong tsa radar, e ka sebelisoa bakeng sa ho feto-fetoha ha lets'oao le ho nyenyefatsa; Tlhahlobong ea bongaka, e ka sebelisoa bakeng sa litšoantšo tsa optical le kalafo. Lisebelisoa tse ncha tsa photoelectric: li-electro-optical modulators li ka boela tsa sebelisoa ho etsa lisebelisoa tse ncha tsa photoelectric, tse kang li-switch tsa electro-optical, optical isolators, joalo-joalo.
5. Melemo le melemo Modulator ea electro-optic e na le melemo e mengata, e kang ho tšepahala ho phahameng, tšebeliso e tlaase ea matla, ho kenya habonolo, boholo bo nyane joalo-joalo. Ka nako e ts'oanang, e boetse e na le litšobotsi tse ntle tsa motlakase le bokhoni bo khahlanong le ho kena-kenana, bo ka sebelisoang bakeng sa phetisetso ea marang-rang le litlhoko tse fapaneng tsa ho sebetsana le matšoao. Leha ho le joalo, modulator ea electro-optic le eona e na le mefokolo e itseng, joalo ka tieho ea phetisetso ea lets'oao, ho bonolo ho sitisoa ke maqhubu a kantle a motlakase. Ka hona, ha u sebelisa electro-optic modulator, hoa hlokahala ho khetha sehlahisoa se nepahetseng ho latela litlhoko tsa sebele tsa kopo ho finyella phello e ntle ea modulation le tshebetso. Ka kakaretso, modulator ea electro-optic ke sesebelisoa sa bohlokoa sa electro-optic converter, se nang le tebello e pharaletseng ea ts'ebeliso likarolong tse ngata tse kang puisano ea optical, spectroscopy le tekanyo ea tekheniki.
Ka tsoelopele e tsoelang pele ea mahlale le mahlale le tlhokahalo e ntseng e eketseha ea lisebelisoa tsa optical tse sebetsang hantle haholo, li-modulator tsa electro-optical li tla ntlafatsoa le ho sebelisoa haholo.
