Zvakanakira uye kukosha kweiyo mutete firimu relium niobate mubatanidzwa microwave Photos
Microwave Photon TechnologyAne zvakanakira bhendi rakakura rekushanda, rakasimba rekugadzirisa kugona uye rakaderera rekutapudza maratidziro emhando yerudzi rweMicrowave Nekudaro, iyo microwave Photon system yakavakirwa pane zvimisikidzo zvine mamwe matambudziko akadai sehuremu hukuru, hurema hwakanyanya kuremerwa Naizvozvo, yakabatanidzwa microwave kabhuku kotamba
Parizvino, Si-yakavakirwa tekinoroji yekubatanidza uye Inp-yakavakirwa tekinoroji yekubatanidza yakave yakawanda uye yakawanda mushure memakore ekuvandudzwa mumunda wekutaurirana kwechokwadi, uye zvigadzirwa zvakawanda zvakaiswa mumusika. Nekudaro, kune iyo approwave Photon Semuenzaniso, iyo silicon Optical switch inoziva nzira yekuchinja, ingave yakavakirwa pamhedzisiro yekudzora, kana kutakura simba rekuputika, izvo zvisingagone kusangana neyekutsvaira
Lithium niobate yagara iri yekutanga sarudzo yekumhanya kwakanyanyaElectro-Optic ModulationZvigadzirwa nekuda kweiyo yakanakisa mutsara weElectro-Optic Estroct. Nekudaro, iyo yetsika lithium niobateElectro-Optical ModulatorYakagadzirwa neiyo mitezo yakakura niiebate kristaro zvinhu, uye saizi yemushini yakakura kwazvo, iyo isingakwanise kusangana nezvinodiwa zvekubatanidzwa microwar tekinoroji. Maitiro ekubatanidza lithium niobate zvinhu zvine mutsara Electro-Optical coefficient mubatanidzwa microwave photomave technology system yave chinangwa chevatsvagiri. Muna 2018, timu yekutsvagisa kubva kuHarvard University muUnited States yakatanga kutaurwa neTekinoroji yeTete. Kubva pamaonero emicrowave Photon application, iyi pepa inoongorora simba uye kukosha kwePharton Expornation tekinoroji yakavakirwa pane yakaonda firithium niobate pane iyo Budwiro reMicrowave Photos.
Yakatetepa firimu lithium niofate zvinyorwa uye firimu rakatetepalithium niobate modulator
Mumakore maviri apfuura, rudzi rutsva rwe lithium nidie zvinyorwa zvakabuda, kureva kuti, iyo lithium yefirimu yakadzika neiyo silica buffer cry pepa. Ridge Wasguides neKuwedzera kweVanopfuura 100 Nanometer vanogona kuiswa muTete Litching Litching Tripment iyo microwave munda kana uchiraira modulator. Nekudaro, zvinobatsira kuti uwane yakaderera hafu-wave voltage uye yakakura modulation bandwidth mune pfupi pfupi.
Kuonekwa kwekuderera kurasikirwa lithium niobate submicron waveguide kupwanya bhodhoro rekutyaira voltage yetsika yeiyo lithium niobate electro-optic modulator. Iyo Electrode spliting inogona kuderedzwa kusvika ~ 5 μm, uye inodarika musango yemagetsi uye iyo Optical Mode inowedzera kwazvo, uye iyo vide inoderera kubva 20 v · cm kusvika pasi pe2,8 v · cm. Naizvozvo, pasi pehafu-mafudzi voltage, kureba kwemushini kunogona kuderedzwa zvakanyanya kuenzaniswa nemunyori wetsika. Panguva imwecheteyo, mushure mekururamisa paramita yehupamhi, kupindirana uye kupindirana kwemaawa ekufamba efaira, sezvakaratidzwa muchimiro, mwero anokwanisa kuwanda-yakakwira bandwidth yakakura kupfuura zana ghz.

Kuenzanisa kweiyo mutete wefirimu blipate modulators neyechinyakare lithium

. Inogona kuoneka kubva patafura iyo yakaonda flithium niobate modulator ine zvinyorwa zviri pachena mu modulation bandwidth, hafu-wave kuperevedza, kupererwa kwekutaura uye zvichingodaro.
Silishon, se dombo rekona yekudyidzana optoelectronics, maitiro akazara, maitiro ayo madiki anokodzera kuunganidzwa kukuru kweanoshanda, uye mwanasikana wayo akadzidziswa zvakanyanya mumunda wekutaurirana kwepfungwa. Iyo Electro-Optical Modulation Mechanism yeSilicon inonyanya kutakura kutakura-toni, inotakura jekiseni uye inotakura kuwanda. Pakati pavo, bandwidth yemukweretesi ane mutsara wekutora degree solids, pamwero wekutakura amplitude uye chiratidzo chekukanganisa.
Iyo Inp Modulator ine yakasarudzika Electro-Optical mhedzisiro, uye iyo yakawanda-layer qualum Nekudaro, kusiyanisa kweiyo Refractive Index ine munda emagetsi kunosanganisira mutsara uye nonlinear mazwi, uye kuwedzera kwemagetsi kusimba kwemunda kuchaita yechipiri-yakarongeka maitiro mukurumbira. Naizvozvo, Silishon uye Inp Electro-Optic Modulators inoda kuisa bias kuti iite pn Junction kana vachishanda, uye pn Junction ichaunza kurasikirwa kwekunyora. Nekudaro, saizi yeModulator yeaya maviri idiki, iyo yekutengeserana inp modulator size ndeye 1/4 ye ln modulator. Kuwedzeredza kufambidzana, kwakakodzera kuwanda kwakakura uye pfupi pfupi digital yedhijitari transmission network yakadai se data nzvimbo. Electro-Optical mhedzisiro yeLithium niobate haina kana mwenje wekunyora maitiro uye kurasikirwa kwakaderera, izvo zvakakodzera kuti ubatanidzwe kwenguva refuOptical kutauriranaine hukuru hukuru uye yakakwira chiyero. Mune microwave photon application, iyo Electro-Optical Coefficients yeSi uye Inps haina kupfupisa, iyo isina kukodzera iyo microwave Photon System iyo yakakwirira mutsara uye yakakura masimba. Iyo lithium nidibate zvinyorwa zvakakodzera kwazvo kuti microwave Photon application nekuda kweiyo yakazara mutsara weElectro-Optic modulation coeffication.
