Zida zophatikizira zowonda tatimu niobate electro-optic

Mgawo lalikuluelectro-opticndi ma microwave bynon
Powonjezera zinthu zowonjezera zozozokhazo zozozokhaza, kuti zitheke kukonza ma signalonations, anthu amawononga matope ndi ma elekitironje kuti akwaniritse zabwino zonse, ndipo mavololove zithunzi zidzakhala zobadwa. Makina a electro-ooneka ofunika kuti asinthe magetsi kuti ayakeMicrowave Phototonic Systems, ndipo njira yofunikira iyi nthawi zambiri imasankha magwiridwe ake onse. Popeza kutembenuka kwa chikwangwani cha wailesima electro-optablealibe tsankho, pamakhala kusokonekera kwakukulu pakusintha. Kuti mukwaniritse kusintha kwa mzere, kugwirira ntchito kwa radiotor nthawi zambiri kumakhazikika pa kiya ya Orthogoneal, koma sikungakwaniritse zofunikira za ma microwave photon kulumikizana kwa mzere wa mzere wa osinthira. Ma electro-opralators okhala ndi malo apamwamba amafunikira mwachangu.

Kusintha kosintha kwambiri kosinthanitsa kwa zida za Silicon nthawi zambiri kumatheka ndiulere kwaulere plasma ermation (FCD). Zonse ziwiri za fcd ndi madyerero a PNS zimasagwirizana, zomwe zimapangitsa simuketon ratulator wocheperako kuposa kirediti ya lithiamu niobate. Zithunzi za Liobate Niobate Zisonyezo ZabwinoZosintha zamagetsikatundu chifukwa cha zotsatira zawo za Pucker. Nthawi yomweyo, zinthu zosonyezera za Liobate Niobate zili ndi maudindo akuluakulu, mikhalidwe yabwino yosinthira, yochepetsetsa ndi siyicon pafupifupi, komanso kukwaniritsa malo ofupikirapo. Makina owonda a lithiate Niobate (Lnoi) electo-opto-optic rodurtor wakhala njira yolimbikitsa yolimbikitsa. Ndi kukula kwa ukadaulo wowonda wa Liobate Niobate Niobate Niobate Ndege, Kutembenuka Kwakunja Kwakutalika Kwamanja ndi Kuphatikizika Kwambiri kwa Filium Niobate Electro-Optic Morector wakhala gawo la maphunziro apadziko lonse la Maphunziro ndi makampani.

Makhalidwe a Woonda Withium Niobate
Ku United States Dap Arr Ar Arforme adapangitsa kuti zinthu zotsatirazi ziziwunika zida zamitundu: ngati likulu la magetsi limatchulidwa, ndiye malo obadwirako zithunzi za zithunzi Izi ndichifukwa choti chifukwa cha lithiate Niobate electro-stuvacal protof, acuutoelection protof, pienzoelectric mphamvu, monganso zinthu za Sicon m'munda wa Opticcs.

Potengera mikhalidwe yotsatsira yotsatsira, zinthu za inp ili ndi gawo lalikulu kwambiri pa chip-kupezeka kwa kuyamwa kwa kuwala kwa 1550nm band. Sio2 ndi silicon nitride ali ndi mawonekedwe abwino operekera, ndipo kutayika kungafike pamlingo wa ~ 0.01db / cm; Pakadali pano, kuwonongeka kwa firoge-filtiate Niobate kukula kwa 0,03db / masentimita, ndi kutaya kwa filimu yopyampyathy niobate kuchepetsedwa ndi kusintha kwaukadaulo mtsogolo. Chifukwa chake, zinthu zowonda zocheperako zimawonetsa ntchito yabwino kwa zojambula zopepuka monga njira zopangira zithunzi zopangira zithunzi.

Pankhani ya m'badwo wopepuka, inp yokha ndiyokhoza kutulutsa kuwala mwachindunji; Chifukwa chake, kuti mugwiritse ntchito zithunzi za microwave, ndikofunikira kuyambitsa gwero la kuwala kwa LNOI ku LOITE CLONONIC yophatikizidwa ndi njira yobwezeretsanso kapena kukula kwa epitaxiya. Pakusintha kwamaganizidwe, kumatsimikizika pamwamba pa zinthu zowonda zozamazi zomwe zimasavuta kukwaniritsa mawu osinthira andhutidth, kutsitsidwa kwamphamvu kwamphamvu ndi kutaya kotsika kuposa inp ndi si. Kuphatikiza apo, malo osokoneza bongo a electro-ma elekication kusinthidwe kwa zinthu zowonda tatium nithiate ndikofunikira kwa onse ma microwave Photon ntchito.

Pankhani ya ma staut owoneka bwino, othamanga othamanga a electro-optical zinthu zowonda za Liobate zimapangitsa kusintha kwamphamvu kwambiri kosinthika, ndipo kumwa kwa mphamvu zosintha kwambiri ndizochepa kwambiri. Pakugwiritsa ntchito ukadaulo wophatikizira wa microwave photos, chip cholumikizidwa bwino chimatha kusintha kwamphamvu kwambiri kuti mukwaniritse zosowa za mtengo wachangu, ndi mawonekedwe a mphamvu yotsika kwambiri ndikuzolowera zizolowezi zamitundu yayikulu. Ngakhale kusintha kwa ipip kosinthasintha kumathanso kusintha kwa mawonekedwe othamanga kwambiri, kumayambitsa phokoso lalikulu, makamaka pomwe kusintha kwa mashopu kusinthidwe kumachitika, kusamvako kumasokonekera. Silicon, Sio2 ndi Siteicon Nitride Zongosinthira njira zowoneka bwino kudzera mu thermo-stuvacal information, omwe ali ndi vuto la kumwa kwambiri. Kuchuluka kwa msinkhu wopakidwa pamalowo ndi kwakukulu, sikungakwaniritse zofunikira za kumwa zamagetsi.

Pankhani ya kukonzedwa kowoneka,Semiconductor Optifal (SoaKutengera Insp kwakhwima chifukwa chogwiritsa ntchito malonda, koma zimakhala ndi zovuta za mphamvu yayikulu yotulutsa ndi mphamvu yotsika, yomwe siyikuyenera kugwiritsa ntchito zithunzi zamagetsi. Njira yowonjezera yopyapyala-filimu ya Liobate Niobate kutengera njira yotsegulira nthawi ndi chipamwamba pa-chip zophatikizira zophatikizira za microwave en-chip zotsekeka.

Pankhani yodziwika bwino, yowonda yowonda ithiamu niobate ali ndi mawonekedwe abwino operekera mu 1550 NM Band. Ntchito ya kutembenuka kwa Photoelectric silingadziwitsidwe Ma units a Ingas kapena Ge-SI amafunika kukhazikitsidwa pa chips taki ophatikizidwa ndi chisimba chodzaza kapena kukula kwa eptitaxial. Pankhani yolumikizira ndi fiberi yopendekera, chifukwa kaphikidwe kazithunzi kani ndi siyi, gawo lozungulira la Sio2 lofananira kwambiri ndi firiji ya fiberi, ndipo kulumikizana ndi koyenera. Mawongolero mulingo wokhazikika wa filimu yopyapyala ithiamu Niobate ali 1μm, yemwe siofanana ndi mawonekedwe a fiber, kotero kusintha koyenera kuyenera kulinganiza gawo la mawonekedwe am'mapapo.

Pakuphatikizidwa, kaya zinthu zosiyanasiyana zimakhala ndi zida zosiyanasiyana zomwe zingatengeke kwambiri pa kugwa kwa radius yam'mphepete mwa fundege (yomwe yakhudzidwa ndi malire a munda wa fundege). Kuundana kokhazikika kumapangitsa kuti ang'ono okhazikika a radius, omwe amathandizanso kukwaniritsidwa kwakukulu. Chifukwa chake, chowonda cha filimu a Liobate Niobate akuyenda ali ndi kuthekera kokwaniritsa kwambiri. Chifukwa chake, maonekedwe owonda a Lithiamu Niobate amapangitsa kuti zinthu zizikamitse zinthu za lithiate kuti zizigwira ntchito ya Stucal "Sicon". Pogwiritsa ntchito zithunzi za microwave, maubwino owonda filimu lithiate Niobate.
