Optical phased array tekinoroji rudzi rutsva rwebeam deflection control tekinoroji, ine mabhenefiti ekuchinjika, kumhanya kukuru uye kunyatsojeka.

Parizvino, tsvakiridzo zhinji dziri pane optical phased array ye liquid crystal, optical waveguide, uye microelectromechanicalsystem (MEMS). Zvatinounzira kwauri nhasi ndizvo zvinoenderana nemisimboti ye optical phased array ye optical waveguide.

Iyo optical waveguide phased array inonyanya kushandisa iyo electro-optical athari kana thermo-optical maitiro eiyo dielectric zvinhu kuita kuti mwenje wemwenje udzoke mushure mekupfuura nemuzvinhu.

Optical Waveguide Phaded Array Based on Electro-Optical Eeffect

Iyo electro-optical effect yekristaro ndeyekushandisa kunze kwemagetsi munda kune kristaro, kuitira kuti chiedza chechiedza chinopfuura nekristaro chinobudisa chikamu chinononoka chine chokuita nemunda wemagetsi wekunze. Zvichienderana neiyo yekutanga electro-optical mhedzisiro yekristaro, kunonoka kwechikamu kunokonzerwa nemunda wemagetsi kunoenderana nemagetsi akaiswa, uye kunonoka kwechikamu chemwenje wechiedza ichipfuura nepakati optical waveguide core inogona kuchinjwa nekudzora magetsi pamhepo. electrode layer yeimwe neimwe optical waveguide core. Kune iyo yakakamurwa mutsara weoptical waveguide ine N-layer waveguide, iyo nheyo inoratidzwa muMufananidzo 1: kufambiswa kwemwenje yemwenje mune yega yega core layer inogona kudzorwa yakazvimirira, uye yayo periodic diffraction mwenje kugovera hunhu hunogona kutsanangurwa ne grating diffraction theory. . Nekudzora iyo yakashandiswa voltage pamusimboti layer zvinoenderana neimwe mutemo kuti tiwane inoenderana chikamu mutsauko kugovera, isu tinokwanisa kudzora kukanganiswa kugoverwa kwekusimba kwechiedza munzvimbo iri kure. Mhedzisiro yekuvhiringidza ndeye yakakwirira-yakanyanya mwenje mwenje mune imwe nzira, ukuwo masaisai emwenje anoburitswa kubva kuchikamu chekutonga mayunitsi mune mamwe mativi anodzima mumwe nemumwe kunze, kuitira kuti uone kutsauka kwechiedza chemwenje.

Optical Waveguide Phased Array Kubva pane Thermo-Optical Effect

Crystal’s thermo-optical effect inoreva chiitiko chekuti kurongeka kwemamorekuru kwekristaro kunoshandurwa nekudziya kana kutonhodza kristaro, izvo zvinokonzeresa kuti optical properties yekristaro ichinje nekushanduka kwetembiricha. Nekuda kweiyo anisotropy yekristaro, iyo thermo-optical mhedzisiro ine zviratidzo zvakasiyana-siyana, izvo zvingave shanduko yehafu-axis kureba kweiyo indicatrix, kana shanduko yeiyo optical axis angle, kutendeuka kweiyo optical axis plane, the kutenderera kwendicatrix, zvichingodaro. Kufanana neiyo electro-optical athari, iyo thermo-optical mhedzisiro inoita simba rakafanana pakutsauka kwedanda. Nekushandura simba rekudziya kushandura iyo inoshanda refractive index ye waveguide, iyo angle deflection mune imwe nzira inogona kuwanikwa. Mufananidzo 2 dhiyabhorosi dhiyagiramu ye optical waveguide phased array zvichibva pane thermo-optical athari. Iwo akaganhurwa akarongwa haana kurongeka zvakaenzana uye akabatanidzwa pane 300mm CMOS mudziyo kuti uwane yepamusoro-inoshanda scanning kutsauka.
