Modulator yeEoNhevedzano: Kumhanya kwakanyanya, voltage yakaderera, diki saizi lithium niobate thin film polarization control device
Mafungu echiedza ari munzvimbo yakasununguka (pamwe chete nemafungu emagetsi emamwe mafrequency) mafungu eshear, uye divi rekuzunguzika kweminda yawo yemagetsi nemagineti rine nzira dzakasiyana siyana dzinobvira muchikamu chakatenderedza divi rekupararira, inova ndiyo polarization property yechiedza. Polarization ine kukosha kwakakosha muminda yekukurukurirana kwemaziso kwakabatana, kuona maindasitiri, biomedicine, kunzwa kwepasi kure, mauto emazuva ano, ndege negungwa.
Muzvisikwa, kuti zvifambe zviri nani, zvipenyu zvakawanda zvakagadzira masisitimu ekuona anogona kusiyanisa polarization yechiedza. Semuenzaniso, nyuchi dzine maziso mashanu (maziso matatu ari ega, maziso maviri akasanganiswa), rimwe nerimwe rine maziso madiki 6,300, anobatsira nyuchi kuwana mepu yepolarization yechiedza kumativi ese mudenga. Nyuchi inogona kushandisa polarization mepu kuti iwane uye itungamirire marudzi ayo kumaruva ainowana. Vanhu havana nhengo dzemuviri dzakafanana nenyuchi kuti vanzwe polarization yechiedza, uye vanofanirwa kushandisa michina yekugadzira kuti vanzwe uye vashandise polarization yechiedza. Muenzaniso wakajairika kushandiswa kwemagirazi epolarization kutungamira chiedza kubva pamifananidzo yakasiyana kuenda kumaziso ekuruboshwe nerudyi mu perpendicular polarizations, inova ndiyo musimboti wemafirimu e3D mu cinema.
Kugadzirwa kwemidziyo yekudzora polarization yemaziso inoshanda zvakanyanya ndiyo kiyi yekugadzira tekinoroji yekushandisa polarized light. Midziyo yakajairika yekudzora polarization inosanganisira polarization state generator, scrambler, polarization analyzer, polarization controller, nezvimwewo. Mumakore achangopfuura, tekinoroji ye optical polarization manipulation iri kukurumidza kufambira mberi uye inobatanidzwa zvakanyanya munzvimbo dzakawanda dziri kubuda dzakakosha zvikuru.
Kutorakutaurirana kwemazisosemuenzaniso, zvichikonzerwa nekudiwa kwekutumira data rakawanda munzvimbo dzedata, kubatana kwenzvimbo refuchiedzaTekinoroji yekutaurirana iri kupararira zvishoma nezvishoma kune mashandisirwo einternet mapfupi anonyanya kukanganiswa nemutengo uye kushandiswa kwesimba, uye kushandiswa kwetekinoroji yekushandura polarization kunogona kuderedza zvinobudirira mutengo uye kushandiswa kwesimba kwemasisitimu ekutaurirana e-optical mafupi. Zvisinei, pari zvino, kutonga polarization kunonyanya kuitwa nezvikamu zve optical zvakasiyana, izvo zvinoderedza zvakanyanya kuvandudzwa kwekushanda uye kudzikiswa kwemutengo. Nekukura nekukurumidza kwetekinoroji yekubatanidza optoelectronic, kubatanidzwa uye chip inzira dzakakosha mukuvandudzwa kwezvishandiso zvekudzora polarization zve optical mune ramangwana.
Zvisinei, mawaveguides e optical akagadzirwa mumakristaro e lithium niobate ane zvazvakaipira zve small refractive index contrast uye weak optical field binding ability. Kune rumwe rutivi, saizi yemudziyo yakakura, uye zvakaoma kusangana nezvinodiwa zvekuvandudza zvekubatanidzwa. Kune rumwe rutivi, electrooptical interaction haina kusimba, uye driving voltage yemudziyo yakakwira.
Mumakore achangopfuura,zvishandiso zvemifananidzoZvishandiso zve lithium niobate zvakafambira mberi munhoroondo, zvichikwanisa kumhanya zvakanyanya uye kudzikira kwevoltage yekutyaira kupfuura zvechinyakare.zvishandiso zve lithium niobate photonic, saka vanofarirwa neindasitiri. Mukutsvaga kwazvino, chip yekubatanidza optical polarization control chip inowanikwa papuratifomu yekubatanidza lithium niobate thin film photonic, inosanganisira polarization generator, scrambler, polarization analyzer, polarization controller nedzimwe mabasa makuru. Maparamendi makuru emachipisi aya, akadai se polarization generation speed, polarization extinction ratio, polarization perturbation speed, uye measurement speed, akaisa rekodhi itsva dzepasi rose, uye akaratidza kushanda kwakanaka mukumhanya kwakanyanya, mutengo wakaderera, pasina parasitic modulation loss, uye low drive voltage. Mhedzisiro yekutsvagisa kekutanga inoratidza kushanda kwepamusoro.lithium niobateZvishandiso zvekudzora polarization yeganda rakatetepa, izvo zvinoumbwa nemayuniti maviri ekutanga: 1. Polarization rotation/splitter, 2. Mach-zindel interferometer (tsananguro >), sezvakaratidzwa muMufananidzo 1.
