WISOPTIC Malangizo a Laser Technology: Mfundo za Optical Phased Array of Optical Waveguide

Tekinoloje ya Optical phased array ndi mtundu watsopano waukadaulo wowongolera mitengo, womwe uli ndi ubwino wosinthasintha, kuthamanga kwambiri komanso kulondola kwambiri.

Pakalipano, kafukufuku wambiri ali pamtundu wa optical phased wa liquid crystal, optical waveguide, ndi microelectromechanicalsystem (MEMS). Zomwe tikubweretserani lero ndi mfundo zofananira za optical phased array of optical waveguide.

Gulu la optical waveguide phased array makamaka limagwiritsa ntchito electro-optical effect kapena thermo-optical effect ya dielectric material kuti kuwala kwa kuwala kusokonezeke pambuyo podutsa zinthuzo.

Kuwala Waveguide Padachita Aray Basd pa Electro-Optical Ezotsatira

Mphamvu ya electro-optical ya kristalo ndiyo kugwiritsa ntchito magetsi akunja kwa kristalo, kotero kuti kuwala kodutsa mu kristalo kumapanga kuchedwa kwa gawo komwe kumakhudzana ndi magetsi akunja. Kutengera mphamvu yayikulu ya kristalo ya electro-optical, kuchedwa kwa gawo komwe kumachitika chifukwa cha magetsi kumayenderana ndi voteji yomwe imagwiritsidwa ntchito, ndipo kuchedwa kwa gawo la kuwala komwe kumadutsa pachimake cha optical waveguide core kungasinthidwe ndikuwongolera mphamvu yamagetsi pamagetsi. electrode wosanjikiza wa aliyense kuwala waveguide pachimake. Pamagawo angapo a mawonekedwe owoneka bwino okhala ndi N-layer waveguide, mfundoyi ikuwonetsedwa mu Chithunzi 1: kufalikira kwa nyali zowala mugawo lililonse lapakati kumatha kuyendetsedwa modziyimira pawokha, ndipo mawonekedwe ake ogawa nthawi ndi nthawi amatha kufotokozedwa ndi chiphunzitso cha grating diffraction. . Poyang'anira magetsi ogwiritsidwa ntchito pamtunda wapakati malinga ndi lamulo linalake kuti tipeze gawo losiyana la kusiyana kwa magawo, tikhoza kulamulira kusokoneza kugawidwa kwa mphamvu ya kuwala kumunda wakutali. Zotsatira za kusokonezedwako ndi kuwala kwamphamvu kwambiri kolowera mbali ina, pomwe mafunde owunikira omwe amatuluka kuchokera kumagulu owongolera gawo kupita mbali zina amalephereka, kuti azindikire kusokonekera kwa kuwala kwa kuwala.

Optical Waveguide Phased Array Kutengera Thermo-Optical Effect

Crystals thermo-optical effect imatanthawuza chodabwitsa kuti makonzedwe a maselo a kristalo amasinthidwa ndi kutentha kapena kuziziritsa kristalo, zomwe zimapangitsa kuti mawonekedwe a kristalo asinthe ndi kusintha kwa kutentha. Chifukwa cha anisotropy ya kristalo, mphamvu ya thermo-optical imakhala ndi mawonetseredwe osiyanasiyana, omwe angakhale kusintha kwa kutalika kwa theka-axis kwa indicatrix, kapena kusintha kwa mbali ya kuwala, kutembenuka kwa ndege ya optical, kuzungulira kwa indicatrix, ndi zina zotero. Mofanana ndi electro-optical effect, mphamvu ya thermo-optical imapangitsanso mphamvu yofanana pa kupatuka kwa mtengowo. Posintha mphamvu yotenthetsera kuti isinthe index yowoneka bwino ya waveguide, kupotoza kwa ngodya kumbali ina kumatha kupezedwa. Chithunzi 2 ndi chithunzi chojambula cha optical waveguide phased array kutengera thermo-optical effect. Gulu lokhazikika silimakonzedwa mofanana ndikuphatikizidwa pa chipangizo cha 300mm CMOS kuti mukwaniritse kusinthasintha kwapamwamba kwambiri.

Chithunzi cha 2 Mfundo zazikuluzikulu za magawo osiyanasiyana a mawonekedwe owoneka bwino otengera mphamvu ya Thermo-Optical
