Eo imodyuliUchungechunge: Isantya esiphezulu, i-voltage ephantsi, ubungakanani obuncinci be-lithium niobate isixhobo sokulawula ifilimu ye-polarization
Amaza okukhanya kwindawo ekhululekileyo (kunye namaza ombane wezinye iifrikhwensi) ngamaza okucheba, kwaye isalathiso sokungcangcazela kwemimandla yawo yombane kunye nemagnethi ineendlela ezahlukeneyo zokuqhelaniswa kwindawo enqamlezileyo ejonge kwicala losasazo, eyipropathi yepolarization. yokukhanya.I-polarization inexabiso elibalulekileyo lesicelo kwiinkalo zonxibelelwano oluhambelanayo lwe-optical, ukufumanisa i-industrial, i-biomedicine, i-sensing ye-earth ekude, imikhosi yanamhlanje, i-aviation kunye nolwandle.
Kwindalo, ukwenzela ukuba uhambe kakuhle, izinto ezininzi eziphilayo ziye zavelisa iinkqubo ezibonakalayo ezikwaziyo ukwahlula i-polarization yokukhanya.Ngokomzekelo, iinyosi zinamehlo amahlanu (amehlo amathathu elinye, amabini ahlangeneyo), ngalinye linamehlo amancinane angama-6 300, anceda iinyosi ukuba zifumane imephu yokwahlukana kokukhanya kuwo onke amacala esibhakabhakeni.Inyosi inokusebenzisa imephu yepolarization ukuze ifumane kwaye ikhokelele ngokuchanekileyo iintlobo zayo kwiintyatyambo ezifumanayo.Abantu abanawo amalungu omzimba afana neenyosi ukuva i-polarization yokukhanya, kwaye kufuneka basebenzise izixhobo ezenziweyo ukuva kunye nokukhohlisa i-polarization yokukhanya.Umzekelo oqhelekileyo kukusetyenziswa kweeglasi ze-polarizing ukuqondisa ukukhanya ukusuka kwimifanekiso eyahlukeneyo ukuya ngasekhohlo nasekunene kwamehlo kwi-polarizations ye-perpendicular, eyona mgaqo we-movie ze-3D kwi-cinema.
Ukuphuhliswa kwezixhobo zokulawula i-polarization ye-optical performance ngundoqo wokuphuhlisa iteknoloji yesicelo sokukhanya.Izixhobo eziqhelekileyo zokulawula i-polarization ziquka i-polarization state generator, i-scrambler, i-polarization analyzer, isilawuli se-polarization, njl. Kwiminyaka yakutshanje, iteknoloji ye-optical polarization manipulation ikhawulezisa inkqubela kwaye idibanisa ngokunzulu kwinani leendawo ezivelayo ezibaluleke kakhulu.
Ukuthathaunxibelelwano lwamehlonjengomzekelo, iqhutywa yimfuno yosasazo olukhulu lwedatha kumaziko edatha, ukuhambelana komgama omde.ukubonaiteknoloji yonxibelelwano ngokuthe ngcembe isasazeka kwizicelo zoqhagamshelwano olufutshane olunovelwano kakhulu kwiindleko kunye nokusetyenziswa kwamandla, kunye nokusetyenziswa kobuchwephesha bokukhohlisa i-polarization kunokunciphisa ngokufanelekileyo iindleko kunye nokusetyenziswa kwamandla eendlela ezimfutshane zonxibelelwano oluhambelanayo lwe-optical.Nangona kunjalo, okwangoku, ulawulo lwepolarization lubonakaliswa ikakhulu ngamacandelo abonakalayo, athintela kakhulu ukuphuculwa komsebenzi kunye nokwehliswa kweendleko.Ngophuhliso olukhawulezayo lwetekhnoloji yokudibanisa i-optoelectronic, ukudibanisa kunye ne-chip yimizila ebalulekileyo ekuphuhlisweni kwezixhobo zokulawula i-optical polarization.
Nangona kunjalo, i-optical waveguides elungiselelwe kwiikristale ze-lithium niobate zendabuko zineziphene zesalathisi esincinci se-refractive index kunye nekhono lokubopha intsimi ebuthathaka.Ngakolunye uhlangothi, ubukhulu besixhobo bukhulu, kwaye kunzima ukuhlangabezana neemfuno zophuhliso lokudibanisa.Ngakolunye uhlangothi, ukusebenzisana kwe-electrooptical kubuthathaka, kwaye i-voltage yokuqhuba isixhobo iphezulu.
Kule minyaka yangoku,izixhobo zefotoNgokusekwe kwi-lithium niobate imathiriyeli yefilimu ebhityileyo yenze inkqubela phambili yembali, ukufikelela kwizantya eziphezulu kunye nombane ophantsi wokuqhuba kunesiqhelo.izixhobo ze-lithium niobate photonic, ngoko ke bayathandwa lishishini.Kuphando lwakutsha nje, i-chip edibeneyo yokulawula i-polarization ye-optical iqondwa kwi-lithium niobate ifilimu ebhityileyo yeqonga lokudibanisa ifotonic, kubandakanya i-polarization generator, i-scrambler, i-polarization analyzer, isilawuli se-polarization kunye neminye imisebenzi ephambili.Iiparamitha eziphambili zezi chips, ezifana nesantya sokuvelisa i-polarization, i-polarization extinction ratio, i-polarization perturbation speed, kunye nesantya sokulinganisa, zisete iirekhodi zehlabathi elitsha, kwaye zibonise ukusebenza okugqwesileyo kwisantya esiphezulu, ixabiso eliphantsi, akukho lahleko lokumodareyitha kwe-parasitic, kunye nezantsi. drive voltage.Iziphumo zophando ngokokuqala ngqa ziqonda uluhlu lwentsebenzo ephezululithium niobateifilimu encinci yezixhobo zokulawula i-polarization optical, eziqulunqwe ngamacandelo amabini asisiseko: 1. Ukujikeleza kwe-polarization / i-splitter, 2. I-interferometer ye-Mach-zindel (inkcazo>), njengoko kuboniswe kuMfanekiso 1.
