Yakakwirira mutsaraElectro-Optic Modulatoruye microwave Photon application
Nezvekuwedzera zvinodiwa zvekutaurirana, kuitira kuti uwedzere kunatsiridza kugona kwekutumira kwezviratidzo, vanhu vachasimbisa mafoto uye maelekitori kuzadzisa zvakanakira, uye microwave emafotiki achazvarwa. Iyo Electro-Optical Modulator inodiwa kuti kushandurwa kwemagetsi kuchiedza mukatiMicrowave Photonic Systems, uye iyi nhanho yakakosha inowanzo tarisa kuita kweiyo yese system. Sezvo kutendeuka kweRadio Frequency Signal kune Optication Domain Iyo Analog chiratidzo maitiro, uye zvakajairikaElectro-Optical ModulatorsIva neisingaonekoshe, pane zvakakomba chiratidzo chekukanganisa mukushandurwa. Kuti uzadzise fungidziro yemutsara, iyo modlatoror inowanzoiswa kuOrthogonal Bias point, asi iyo haigoni kuzadzisa zvinodiwa zveMicrowave Photon link yemutsara weModulator. Electro-Optic modulators ine refu mutsara unodiwa nekukurumidza.
Iyo yakakwira-yekumhanyisa Refractive yekunyorwa kwemidziyo yeSilicon inowanzo kuwanikwa neyemahara yekutakura plasma kupararira (FCD) maitiro. Zvese zviri zviviri FCD Mhedzisiro uye PN Junction modulation ndeye isiri-iyo inoita iyo silicon modulator isina mutsara kupfuura iyo lithium nidiabate modulator. Lithium niobate zvinhu zvinoratidzira zvakanakaElectro-Optical Modulationzvivakwa nekuda kwekuita kwavo pucker maitiro. Panguva imwecheteyo, Lithium nidiebate zvinyorwa zvezvakanaka zvebhandi bandwidth, kurasikirwa neyakaderera, kushandiswa kweiyo Silish Moducon, kana uchienzaniswa neSilicon Yakatetepa firimu raium Nekuvandudzwa kweiyo mutete wefirimu rebliyamu
Hunhu hwefirimu hwakatetepa lithium niobate
MuUnited States DAP AR kuronga kuongororwa kweLithium Nidiuate zvinhu: Kana nzvimbo yekuchinja kwemagetsi inotumidzwa mushure mezvinyorwa zveSilicon zvinokwanisika, saka nzvimbo yekuzvarwa yeThotonic inogona kutumidzwa zita mushure meLithium Niobate. Izvi zvinodaro nekuti Lithium niobate inobatanidza Electro-Optical mhedzisiro, Acousto-Optical mhedzisiro, iyo's Photorefraction Elders mune imwe, seSilicon Zvigadzirwa Mumunda Wemunda weEptics.
Panyaya yeye Optical Transistics, Inp zvinyorwa zvine hombe pane-chip kutapurirana kurasikirwa nekuda kwekunyura kwechiedza mune inowanzoshandiswa 1550nm band. SIO2 uye Silicon Nitreide ine iyo yakanakisa kutapurirana maitiro, uye kurasikirwa kunogona kusvika padanho re ~ 0.01DB / cm; Parizvino, iyo Wimbguide kurasikirwa kweiyo tete-filum lithium niobate waveguide inogona kusvika kune yakaonda-flip Naizvozvo, iyo yakaonda firimu rebate zvinhu zvinoratidza kuita kwakanaka kwezvinhu zvevakangoita seyakagadzirwa semapikicha nzira, shutors.
Maererano nechizvarwa chechiedza, chete inp ine kugona kwezvibodzwa mwenje zvakananga; Naizvozvo, kuti ishandiswe yemicrowave mifananidzo, inodikanwa kuunza iyo Inp yakavakirwa mwenje tsime pane lnoi yakavakirwa phonic yakabatanidzwa Chip nemaThe Bestloading Welding kana Epitaxial kukura. Panyaya yechiedza modulation, yakasimbiswa pamusoro peiyo flit lithium yedhium Zvakare, iyo yakakwira mutsara weElectro-Optical modulation yeiyo yakaonda firimu lithium niobate zvinhu zvakakosha kune ese microwave photon application.
Panyaya yeOptical Routisto, Yekumhanya Yakakura Electro-Optical Mhinduro yeFirit yeFliyum Switch Switch Switch Switch Zvekunyorwa chaiko kwekubatanidzwa microwar tekinoroji, iyo yakatorwa mhiri kweChiratidzo yekukwira kweBeam Scanning Kunyangwe iyo Inp yakavakirwa Optical switch inogona zvakare kuziva nzira yepamusoro yekukwira, ichaunza ruzha rukuru Silishon, Silicon Nitride Zvigadzirwa zvinogona kungochinja nzira dzepfungwa kuburikidza neTermo-Optical Aperpersancess, iyo ine zvakashata zvekushandisa masimba uye zvishoma nezvishoma switching kumhanya. Kana saizi yehurongwa hwePhosed yakakura, haigoni kusangana nezvinodiwa zvekushandisa simba.
Maererano neye Optical Amplization, iyoSemiconductor Optical Amplifier (Soa) Kubva pane inp yanga yave yakakura yekushandisa kwekutengeserana, asi ine zvakashata zvekutakura ruzha uye yakaderera yekubuda simba simba, iyo isingakwanisi kushandiswa kweiyo microwave photos. Iyo paramentric Amplization Process yeTete-film lithium niobate tempuides
Panyaya yekuona kwechiedza, iyo yakatetepa flithium niobate ine yakanaka kutapurika maitiro kune chiedza mu 1550 NM band. Basa rekushandurwa kweTheyelectric risingakwanisi kuzadziswa, saka nekuda kwemicrowave Photon application, kuitira kuti vasangane nezvinodiwa zveTheyelectric kutendeuka pane chip. Ingaas kana ge-si yekuona zvikamu zvinoda kuunzwa pane lnoi yakavakirwa phonic yakabatanidzwa machipisi nekudzosera kumashure kwelding thelding kana Epitaxial kukura. Panyaya yekubatanidza neyekupedzisira fiber, nekuti iyo Optical fiber pachayo ndeye Sti2 Chinyorwa, iyo Mode Madhaya Wimbguide ine mwero wepamusoro weiyo Optical fiber, uye coupling ndiyo yakanyanya nyore. Iyo Mode Field Diamita yeiyo yakasimba inoganhurirwa waveguide yeTete firimu remafirimu remagetsi
Panyaya yekubatanidza, ingave yakasiyana-siyana ine midziyo yekubatanidza zvakanyanya inoenderana zvakanyanya pane yekukotama radius ye waveguide (inokanganiswa neiyo miganhu ye waveguide moda). Iyo yakasarudzika inosimbisa waveguide inobvumira idiki diki yekukomba radius, iyo inonyanya kufadza pakuzadziswa kwekubatana kwakanyanya. Naizvozvo, mutete-firimu lithium niobate waveguides ane mukana wekuti uwane zvakanyanya kubatanidzwa. Naizvozvo, kutaridzika kweiyo mutete firimu refliyamu, kunoita kuti zviitike kuti Lithium nidium zvinhu kuti zvinyatsoita basa renyaya ye "silicon". Kuti ishandiswe yeMicrowave Photowrs, zvakanakira zvevatete firimu refirimu renhabvu.
