Sebopeho salisebelisoa tsa puisano tsa optical
Sistimi ea puisano e nang le leqhubu la leseli e le lets'oao le fiber ea Optical joalo ka mokhoa oa phetiso o bitsoa sistimi ea puisano ea fiber ea Optical. Melemo ea puisano ea fiber ea optical ha e bapisoa le puisano ea mohala oa setso le puisano e se nang mohala ke: bokhoni bo boholo ba puisano, tahlehelo e tlase ea phetisetso, bokhoni bo matla ba ho kena-kenana le motlakase oa motlakase, ho boloka lekunutu le matla, 'me thepa e tala ea optical fiber transmission medium ke silicon dioxide e nang le polokelo e ngata. Ntle le moo, fiber ea optical e na le melemo ea boholo bo nyane, boima bo bobebe le theko e tlase ha e bapisoa le mohala.
Setšoantšo se latelang se bontša likarolo tsa potoloho e bonolo ea photonic e kopantsoeng:laser, tšebeliso ea optical hape le sesebelisoa sa demultiplexing,photodetectorlemoduthara.
Sebopeho sa mantlha sa optical fiber bidirectional communication system se kenyelletsa: transmitter ea motlakase, transmitter optical, transmitter fiber, optical receiver le moamoheli oa motlakase.
Letšoao la motlakase le lebelo le phahameng le kentsoe ke mochini o fetisang motlakase ho transmitter ea optical, e fetoletsoeng ho mats'oao a optical ka lisebelisoa tsa electro-optical joalo ka Laser device (LD), ebe e kopantsoe le fiber ea phetiso.
Kamora phetisetso e telele ea lets'oao la optical ka fiber ea mofuta o le mong, erbium-doped fiber amplifier e ka sebelisoa ho holisa lets'oao la optical le ho tsoela pele ho fetisoa. Ka mor'a qetello ea ho amohela optical, letšoao la optical le fetoloa letšoao la motlakase ka PD le lisebelisoa tse ling, 'me letšoao le amoheloa ke moamoheli oa motlakase ka ts'ebetso ea motlakase e latelang. Mokhoa oa ho romela le ho amohela lipontšo ka tsela e fapaneng e tšoana.
E le hore ho finyelloe maemo a lisebelisoa ka har'a sehokelo, mochine oa optical transmitter le optical receiver sebakeng se le seng butle-butle ba kenngoa ho Transceiver ea optical.
Lebelo le leholoMojule oa optical transceivere entsoe ka Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) e emeloa ke lisebelisoa tse sebetsang tsa optical, lisebelisoa tse sa sebetseng, li-circuits tse sebetsang le likarolo tsa sebopeho sa photoelectric li kenngoa. lisebelisoa tsa optical.
Ha ba tobane le bothata ba 'mele le mathata a botekgeniki a kopaneng le nts'etsopele ea theknoloji ea microelectronics, batho ba ile ba qala ho sebelisa li-photon joalo ka bajari ba tlhahisoleseling ho fihlela bandwidth e kholoanyane, lebelo le phahameng, tšebeliso e tlase ea matla, le tieho e tlase ea photonic inteated circuit (PIC). Sepheo sa bohlokoa sa photonic integrated loop ke ho lemoha ho kopanngoa ha mesebetsi ea tlhahiso ea leseli, ho kopanya, ho feto-fetoha ha molumo, ho hloekisa, ho fetisetsa, ho lemoha joalo-joalo. Matla a pele a ho khanna a lipotoloho tse kopantsoeng tsa photonic a tsoa puisanong ea data, 'me joale e ntlafalitsoe haholo ho microwave photonics, quantum information processing, nonlinear optics, sensors, lidar le masimo a mang.
