Ho hlahloba liphiri tsa leseli: Likopo tse ncha tsaElectro-Optic Modulator LiNbO3 phase modulator

LiNbO3 modulatorPhase modulator ke ntho ea bohlokoa e ka laolang phetoho ea leqhubu la leseli, 'me e bapala karolo ea mantlha puisanong ea sejoale-joale ea optical le kutlo. Haufinyane tjena, mofuta o mocha oamodulator ea mohatoe hohetse tlhokomelo ea bafuputsi le baenjiniere, e sebetsang ka maqhubu a mararo a 780nm, 850nm le 1064nm, ka li-bandwidth tsa modulation tse fihlang ho 300MHz, 10GHz, 20GHz le 40GHz.

Tšobotsi ea bohlokoa ka ho fetisisa ea modulator ena ea mohato ke bandwidth e phahameng ea modulation le tahlehelo e tlaase ea ho kenya. Tahlehelo ea ho kenya e bolela ho fokotseha ha matla kapa matla a lets'oao la optical kamora ho feta modulator. Tahlehelo ea ho kenngoa ha modulator ena ea mohato e tlaase haholo, e leng se tiisang botšepehi ba pontšo, e le hore letšoao le ka boloka matla a phahameng ka mor'a ho feto-fetoha.

Ntle le moo, modulator ea mekhahlelo e na le sebopeho sa motlakase o tlase oa halofo ea maqhubu. Half-wave voltage ke motlakase o lokelang ho sebelisoa ho modulator ho fetola karolo ea leseli ka likhato tse 180. Motlakase o tlase oa halofo ea maqhubu o bolela hore ho hlokahala feela motlakase o fokolang ho finyella phetoho e kholo karolong ea optical, e leng ho fokotsang haholo tšebeliso ea matla ea sesebelisoa.

Mabapi le likarolo tsa ts'ebeliso, modulator ena e ncha ea karolo e ka sebelisoa haholo ho optical fiber sensing, optical fiber communication, ho lieha ha mohato (shifter), le puisano ea quantum. Ho optical fiber sensing, modulator ea mohato e ka ntlafatsa kutloisiso le tharollo ea kutlo. Puisanong ea optical fiber, e ka ntlafatsa lebelo la puisano le katleho ea phetiso ea data. Ka ho lieha ha mohato (shifter), e ka laola ka nepo tsela ea ho hasana ha leseli; Puisanong ea quantum, e ka sebelisoa ho laola le ho laola maemo a quantum.

Ka kakaretso, modulator e ncha ea karolo e re fa mekhoa e sebetsang hantle le e nepahetseng ea taolo ea optical, e tla tlisa liphetoho tsa phetoho mafapheng a mangata. Re lebelletse hore theknoloji ena e tla ntlafatsoa le ho phethahala nakong e tlang, e re senolele liphiri tse ngata tsa mahlo.
