Kunzwisisa kwakazara kwe electro-optic modulators
Iyo Electro-optic modulator (EOM) i-electro-optic converter inoshandisa zviratidzo zvemagetsi kudzora zviratidzo zvemaziso, zvinonyanya kushandiswa mumashandisirwo emagetsi ekutendeuka mumunda weTechnology tekinoroji.
Izvi zvinotevera sumo yakadzama kune electro-optic modulator:
1. Nheyo yekutanga yeelectro-optic modulatorinobva pane electro-optic effect, kureva, refractive index yezvimwe zvinhu zvinoshanduka pasi pechiito chemunda wemagetsi wakashandiswa. Sezvo masaisai echiedza achipfuura nepakati pemakristasi aya, maitiro ekuparadzira anoshanduka nemunda wemagetsi. Uchishandisa musimboti uyu, chikamu, amplitude kana polarization mamiriro eiyoopticalchiratidzo chinogona kudzorwa nekushandura iyo inoshandiswa yemagetsi munda.
2. Mamiriro uye kuumbwa Electro-optical modulators kazhinji inoumbwa neoptical paths, amplifiers, filters uye photoelectric converters. Mukuwedzera, inosanganisira zvikamu zvakakosha zvakadai semadhiraivha ekumhanya-mhanya, optical fibers uye piezoelectric crystals. Mamiriro e electro-optic modulator anogona kusiyana zvichienderana neayo modulation modulation uye application zvinodiwa, asi kazhinji inosanganisira zvikamu zviviri: electro-optic inverter module uye photoelectric modulation module.
3. Modulation mode Electro-optic modulator ine maviri makuru modulation modes:phase modulationuye intensity modulation. Phase modulation: Chikamu chemutakuri chinoshanduka sezvo modulated chiratidzo chinoshanduka. MuPockels electro-optic modulator, carrier-frequency light inopfuura nepapiezoelectric crystal, uye kana modulated voltage ikaiswa, munda wemagetsi unogadzirwa mupiezoelectric crystal, zvichiita kuti refractive index ichinje, nokudaro ichichinja chikamu chechiedza. .Kusimba modulation: Kusimba (kusimba kwechiedza) kweiyo optical carrier inoshanduka sezvo modulated chiratidzo chinoshanduka. Kusimba modulation kunowanzo kuwanikwa uchishandisa Mach-Zehnder intensity modulator, iyo yakaenzana musimboti neMach-Zehnder interferometer. Mushure mekunge matanda maviri aya agadziridzwa nechikamu chekuchinja ruoko zvine masimba akasiyana, anozokanganiswa kuti awane intensity modulated optical signal.
4. Nzvimbo dzekushandisa Electro-optical modulators dzine huwandu hwakawanda hwemashandisirwo mune akati wandei minda, kusanganisira asi isina kuganhurirwa kune: optical communication: Mune yakakwirira-speed optical communication masisitimu, electro-optical modulators inoshandiswa kushandura masaini emagetsi kuita masaini masaini. kuti uwane data encoding uye kutapurirana. Nekugadzirisa kusimba kana chikamu chechiratidzo chemaziso, mabasa ekuchinja kwechiedza, modulation rate control uye signal modulation inogona kuitika. Spectroscopy: Electro-optical modulators inogona kushandiswa sezvikamu zve optical spectrum analyzers ye spectral ongororo uye kuyerwa. Tekinoroji kuyerwa: electro-optical modulators zvakare inoita basa rakakosha mu radar masisitimu, kuongororwa kwekurapa uye mamwe minda. Semuenzaniso, mune radar masisitimu, inogona kushandiswa pachiratidzo modulation uye demodulation; Mukuongororwa kwechiremba, inogona kushandiswa kukufungidzira kwemaziso uye kurapwa. Midziyo mitsva yemafotoelectric: electro-optical modulators inogona zvakare kushandiswa kugadzira mitsva yemifananidzo yemagetsi, senge electro-optical switch, optical isolators, nezvimwe.
5. Zvakanakira uye zvisingabatsiri Electro-optic modulator ine zvakawanda zvinobatsira, zvakadai sekuvimbika kwepamusoro, kushandiswa kwesimba shoma, kuiswa nyore, hukuru hukuru nezvimwe zvakadaro. Panguva imwecheteyo, inewo maitiro akanaka emagetsi uye anti-kupindira kugona, iyo inogona kushandiswa pakufambiswa kwebroadband uye zvakasiyana-siyana zvekugadzirisa zviratidzo. Nekudaro, iyo electro-optic modulator inewo zvimwe zvinokanganisa, senge chiratidzo chekunonoka kutapurirana, zviri nyore kukanganiswa nemafungu ekunze emagetsi. Naizvozvo, kana uchishandisa electro-optic modulator, zvinodikanwa kuti usarudze chigadzirwa chakakodzera zvinoenderana nechaiyo application inoda kuwana yakanaka modulation mhedzisiro uye kuita. Muchidimbu, iyo electro-optic modulator yakakosha ye electro-optic converter, ine tarisiro yekushandiswa kwakakura mundima dzakawanda senge optical communication, spectroscopy uye chiyero chehunyanzvi.
Nekuenderera mberi kwekuenderera mberi kwesainzi uye tekinoroji uye kuwedzera kuri kudiwa kwepamusoro-inoshanda optical zvishandiso, electro-optical modulators ichave yakanyanya kuvandudzwa uye kushandiswa.
