Kunzwisisa kwakazara kwema electro-optic modulators
Modulator yeElectro-optic (EOM) ishandisi yemagetsi inoshandisa masaini emagetsi kudzora masaini emaziso, inonyanya kushandiswa mukushandura masaini emaziso mumunda wetekinoroji yekutaurirana.
Zvinotevera ndizvo zvinotsanangurwa zvakadzama nezve electro-optic modulator:
1. Nheyo huru yemodulator yemagetsi-opticyakavakirwa pamhedzisiro yeelectro-optic, kureva kuti, refractive index yezvimwe zvinhu ichachinja kana simba remagetsi rashandiswa. Sezvo mafungu echiedza achipfuura nemakristaro aya, hunhu hwekupararira hunochinja nesimba remagetsi. Uchishandisa musimboti uyu, mamiriro echikamu, amplitude kana polarization yechiedzachiratidzo chinogona kudzorwa nekushandura munda wemagetsi uri kushandiswa.
2. Maumbirwo uye magadzirirwo Mamodulators emagetsi anowanzo umbwa nenzira dzemagetsi, ma amplifiers, mafirita uye ma photoelectric converters. Pamusoro pezvo, ine zvinhu zvakakosha zvakaita semadhiraivha anomhanyisa, ma fibers emagetsi uye makristaro e piezoelectric. Maumbirwo emodulator yemagetsi anogona kusiyana zvichienderana ne modulation mode yayo uye zvinodiwa zvekushandisa, asi kazhinji inosanganisira zvikamu zviviri: electro-optic inverter module uye photoelectric module.
3. Modulation mode Electro-optic modulator ine nzira mbiri huru dze modulation:modulation yechikamuuye kuchinjika kwesimba. Kuchinjika kwechikamu: Chikamu chemutakuri chinochinja sezvo chiratidzo chakachinjika chichichinja. MuPockels electro-optic modulator, chiedza chemutakuri chinopfuura nepa piezoelectric crystal, uye kana voltage yakachinjika ikashandiswa, munda wemagetsi unogadzirwa mu piezoelectric crystal, zvichiita kuti refractive index yayo ichinje, nokudaro ichichinja chikamu chechiedza.Kuchinja kwesimba: Simba (chiedza) remuchina we optical carrier rinochinja sezvo chiratidzo chakagadziriswa chinochinja. Kuchinja kwesimba kunowanzoitwa uchishandisa Mach-Zehnder intensity modulator, iyo yakaenzana neMach-Zehnder interferometer. Mushure mekunge matanda maviri agadziriswa ne phase shifting arm ine simba rakasiyana, anozopedzisira akanganiswa kuti awane chiratidzo che optical chakagadziriswa.
4. Nzvimbo dzekushandisa Electro-optical modulators dzine mashandisirwo akasiyana-siyana munzvimbo dzakasiyana-siyana, kusanganisira asi kwete chete: kutaurirana kwemaziso: Mumasisitimu ekukurukurirana kwemaziso anomhanya zvakanyanya, mamodulators emagetsi-optical anoshandiswa kushandura masaini emagetsi kuita masaini emaziso kuti awane data encoding uye transmission. Nekugadzirisa simba kana chikamu chechiratidzo chemaziso, mabasa ekuchinja chiedza, modulation rate control uye signal modulation anogona kuitwa. Spectroscopy: Electro-optical modulators anogona kushandiswa sezvikamu zve optical spectrum analyzers yekuongorora nekuyera spectral. Kuyera kwehunyanzvi: electro-optical modulators inoitawo basa rakakosha mumasisitimu eradar, diagnostics yezvekurapa nedzimwe nzvimbo. Semuenzaniso, mumasisitimu eradar, inogona kushandiswa pakuchinja masaini uye demodulation; Mukuongororwa kwezvekurapa, inogona kushandiswa pakufungidzira kwemaziso nekurapa. Midziyo mitsva ye photoelectric: electro-optical modulators inogonawo kushandiswa kugadzira zvishandiso zvitsva zve photoelectric, zvakaita se electro-optical switches, optical isolators, nezvimwewo.
5. Zvakanakira nezvayakaipira Electro-optic modulator ine zvayakanakira zvakawanda, zvakaita sekuvimbika kwakanyanya, kushandiswa kwesimba shoma, kuiswa kuri nyore, saizi diki nezvimwewo. Panguva imwe chete, inewo hunhu hwakanaka hwemagetsi uye kugona kudzivirira kukanganiswa, izvo zvinogona kushandiswa pakutumira broadband uye zvakasiyana-siyana zvinodiwa pakugadzirisa masaini. Zvisinei, electro-optic modulator inewo zvimwe zvikanganiso, zvakaita sekunonoka kwekutumira masaini, nyore kukanganiswa nemafungu emagetsi ekunze. Saka, pakushandisa electro-optic modulator, zvakakosha kusarudza chigadzirwa chakakodzera zvichienderana nezvinodiwa chaizvo kuti uwane modulation effect yakanaka uye mashandiro. Mukupfupisa, electro-optic modulator i electro-optic converter inokosha, ine mukana wakakura wekushandisa munzvimbo dzakawanda dzakadai se optical communication, spectroscopy uye technical measurement.
Nekufambira mberi kuri kuramba kuchiitwa nesainzi netekinoroji uye kudiwa kuri kuramba kuchikwira kwezvishandiso zvemagetsi zvinoshanda zvakanyanya, mamodulator emagetsi-optical achagadzirwa uye kushandiswa zvakanyanya.
