Kuumbwa kwemidziyo yekutaurirana yemaziso

Kuumbwa kwezvishandiso zvekutaurirana zve optical

Sisitimu yekutaurirana ine wave yechiedza sechiratidzo uye Optical fiber senzira yekutumira inonzi Optical fiber communications system. Zvakanakira kutaurirana ne optical fiber zvichienzaniswa nekutaurirana kwetambo dzechinyakare uye kutaurirana kwewaya dzisina waya ndeizvi: kugona kukuru kwekutaurirana, kurasikirwa kwekutumira kwakaderera, kugona kwakasimba kwekudzivirira magineti, kuvanzika kwakasimba, uye zvinhu zvakagadziriswa zve optical fiber transmission medium isilicon dioxide ine nzvimbo yakawanda yekuchengetera. Pamusoro pezvo, optical fiber ine zvakanakira zvehukuru hudiki, huremu hwakareruka uye mutengo wakaderera zvichienzaniswa netambo.
Dhayagiramu inotevera inoratidza zvikamu zvedunhu rakapfava re photonic:laser, kushandiswazve kwemaziso uye mudziyo wekubvisa zvinhu zvakawanda,mudziyo wekuona fotouyemodulator.

Maumbirwo ehurongwa hwekutaurirana hwe optical fiber anosanganisira: transmitter yemagetsi, transmitter yemaziso, transmission fiber, optical receiver uye electrical receiver.
Chiratidzo chemagetsi chinomhanya zvikuru chinonyorwa nechinhu chinotumira magetsi kuenda kune chinotumira magetsi, choshandurwa kuita zviratidzo zvemagetsi nemidziyo yemagetsi yakaita seLaser device (LD), uye chobva chabatanidzwa kune faibha yekutumira magetsi.
Mushure mekutumirwa kwechiratidzo che optical kure kure kuburikidza ne single-mode fiber, erbium-doped fiber amplifier inogona kushandiswa kuwedzera chiratidzo che optical uye kuramba ichitumirwa. Mushure mekusvika kwekupedzisira kwekugamuchira kwe optical, chiratidzo che optical chinoshandurwa kuita chiratidzo chemagetsi nePD nezvimwe zvishandiso, uye chiratidzo chinogamuchirwa nemagetsi anogamuchira kuburikidza nemagetsi anotevera. Maitiro ekutumira nekugamuchira masaini kune rimwe divi akafanana.
Kuti michina iri mu link ikwanise kuenzaniswa, optical transmitter ne optical receiver zviri panzvimbo imwe chete zvinobatanidzwa zvishoma nezvishoma mu optical Transceiver.
Kumhanya kwakanyanyaModule ye transceiver yemazisoinoumbwa neReceiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) inomiririrwa nemidziyo inoshanda ye optical, zvishandiso zvisingashande, ma functional circuits uye zvikamu zve photoelectric interface zvinoiswa. ROSA neTOSA zvinoiswa nema lasers, photodetectors, nezvimwewo muchimiro chema optical chips.

Vachitarisana nematambudziko ekugadzira tekinoroji ye microelectronics, vanhu vakatanga kushandisa ma photon senzira yekutakura ruzivo kuti vawane bandwidth yakakura, kumhanya kwakanyanya, kushandiswa kwesimba kwakaderera, uye kuderedza kunonoka kwe photonic inteated circuit (PIC). Chinangwa chakakosha che photonic integrated loop ndechekubatanidza mabasa ekugadzira chiedza, kubatana, modulation, filtering, transmission, detection nezvimwewo. Simba rekutanga re photonic integrated circuits rinobva mukutaurirana kwedata, uye rakagadzirwa zvakanyanya mu microwave photonics, quantum information processing, nonlinear optics, sensors, lidar nedzimwe nzvimbo.
