Eo modulatorSeries: High kumhanya, yakaderera voltage, diki saizi lithium niobate yakaonda firimu polarization control mudziyo
Mafungu echiedza munzvimbo yemahara (pamwe nemafungu emagetsi emamwe mafrequencies) mafungu eshear, uye kutungamira kwekuzunguza kwemagetsi ayo uye magineti minda ine akasiyana anogoneka ekutungamira muchikamu chemuchinjikwa perpendicular kune nzira yekuparadzira, inova nzvimbo yepolarization. yechiedza. Polarization ine kukosha kwekushandisa kwakakosha muminda yekubatana kwekuonana kwemaziso, kuona kwemaindasitiri, biomedicine, kunzwa kure kure, mauto emazuva ano, kubhururuka nendege uye nyanza.
Muzvisikwa, kuitira kuti zvifambe zvirinani, zvipenyu zvakawanda zvakachinja masisitimu ekuona anogona kusiyanisa polarization yechiedza. Semuenzaniso, nyuchi dzine maziso mashanu (maziso matatu ega, maviri akabatana), rimwe nerimwe rine maziso madiki 6,300, anobatsira nyuchi kuwana mepu yepolarization yechiedza mumativi ese mudenga. Nyuchi inogona kushandisa mepu yepolarization kutsvaga uye kunyatsotungamira mhando dzayo kumaruva ainowana. Vanhu havana nhengo dzemuviri dzakafanana nenyuchi kuti vanzwe polarization yechiedza, uye vanofanirwa kushandisa midziyo yekugadzira kunzwa nekushandisa polarization yechiedza. Muenzaniso wakajairika ndeyekushandiswa kwemagirazi epolarizing kutungamira mwenje kubva kumifananidzo yakasiyana kuenda kuruboshwe nekurudyi maziso mune perpendicular polarizations, inova musimboti wemafirimu e3D mubhaisikopo.
Iko kuvandudzwa kwepamusoro pekuita optical polarization control zvishandiso ndiyo kiyi yekugadzira polarized light application tekinoroji. Midziyo yemhando yepolarization control inosanganisira polarization state jenareta, scrambler, polarization analyzer, polarization controller, etc. Mumakore achangopfuura, optical polarization manipulation tekinoroji iri kukurumidza kufambira mberi uye ichibatanidza zvakadzama munzvimbo dzinoverengeka dziri kubuda dzakakosha zvikuru.
Kutoraoptical communicationsemuenzaniso, inotungamirwa nekudiwa kwekufambiswa kukuru kwedata munzvimbo dzedata, kureba kwakabatana.opticaltekinoroji yekukurukurirana iri kupararira zvishoma nezvishoma kune mapfupi-renji ekubatanidza maapplication ayo anotarisisa zvakanyanya kumutengo uye simba rekushandisa, uye kushandiswa kwepolarization manipulation tekinoroji kunogona kunyatso kudzikisa mutengo uye simba rekushandisa kwepfupi-range yakabatana optical communication masisitimu. Nekudaro, parizvino, kutonga kwepolarization kunonyanya kuwanikwa ne discrete optical components, izvo zvinotadzisa zvakanyanya kuvandudzwa kwekuita uye kuderedzwa kwemutengo. Nekukurumidza kukurumidza kwe optoelectronic yekubatanidza tekinoroji, kubatanidzwa uye chip maitiro akakosha mune ramangwana kuvandudza kwe optical polarization control zvishandiso.
Nekudaro, iwo optical waveguides akagadzirirwa mune echinyakare lithium niobate makristasi ane zvazvakaipira zvediki refractive index musiyano uye isina simba yekuona munda inosunga kugona. Kune rumwe rutivi, saizi yemuchina yakakura, uye zvakaoma kuzadzisa zvinodiwa zvekusimudzira zvekubatanidzwa. Kune rumwe rutivi, kupindirana kwe electrooptical hakuna simba, uye dhiraivha yekutyaira yechigadzirwa yakakwirira.
Mumakore achangopfuura,photonic zvishandisozvichibva pa lithium niobate dzakatetepa firimu zvinhu zvakagadzira nhoroondo kufambira mberi, kuwana kumhanya kwepamusoro uye kuderera kwekutyaira kwekutyaira pane yechinyakare.lithium niobate photonic zvishandiso, saka vanofarirwa neindasitiri. Mutsvagiridzo ichangoburwa, iyo yakabatanidzwa optical polarization control chip inowanikwa pane lithium niobate yakaonda firimu photonic yekubatanidza chikuva, kusanganisira polarization jenareta, scrambler, polarization analyzer, polarization controller uye mamwe mabasa makuru. Iwo makuru maparamendi emachipi aya, akadai sepolarization chizvarwa kumhanya, polarization extinction ratio, polarization perturbation kumhanya, uye kuyerwa kweyero, yakaisa marekodhi epasi rose, uye yakaratidza kuita kwakanakisa mukumhanya kukuru, mutengo wakaderera, hapana parasitic modulation kurasikirwa, uye yakaderera. drive voltage. Mhedzisiro yekutsvagisa kekutanga kuona nhevedzano yepamusoro-kuitalithium niobatethin film optical polarization control devices, iyo inoumbwa nezvikamu zviviri zvinokosha: 1. Polarization rotation / splitter, 2. Mach-zindel interferometer (tsanangudzo>), sezvinoratidzwa mumufananidzo 1.
