Ubuchwepheshe be-Optical phased array wuhlobo olusha lobuchwepheshe bokulawula ukuchezuka kwe-beam, obunobuhle bokuguquguquka, isivinini esikhulu kanye nokunemba okuphezulu.

Njengamanje, ucwaningo oluningi lukuhlu lwe-optical phased ye-liquid crystal, i-optical waveguide, ne-microelectromechanicalsystem (MEMS). Esikulethela kona namuhla imigomo ehlobene yohlu olunezigaba olubonakalayo lwe-optical waveguide.

I-optical waveguide phased array ikakhulukazi isebenzisa umthelela we-electro-optical noma umphumela we-thermo-optical wento ye-dielectric ukuze wenze i-beam yokukhanya iphambukise ngemva kokudlula kwinto.

I-Optical Waveguide Phased Aray Bkuqhubeke Ei-lectro-Oi-ptical Eumphumela

Umphumela we-electro-optical we-crystal uwukusebenzisa inkambu kagesi yangaphandle ku-crystal, ukuze i-beam yokukhanya edlula i-crystal ikhiqize ukulibaziseka kwesigaba esihlobene nensimu yangaphandle kagesi. Ngokusekelwe kumthelela oyinhloko we-electro-optical wekristalu, ukubambezeleka kwesigaba okubangelwa inkambu kagesi kuyalingana ne-voltage esetshenzisiwe, futhi ukubambezeleka kwesigaba sokukhanya okudlula ku-optical waveguide core kungashintshwa ngokulawula i-voltage kugesi. Isendlalelo se-electrode ye-optical waveguide core ngayinye. Ohlelweni olunezigaba lwamagagasi okukhanya ane-N-layer waveguide, umgomo uboniswa kuMfanekiso 1: ukudluliswa kwemishayo yokukhanya kungqimba ngayinye eyinhloko kungalawulwa ngokuzimela, futhi izici zayo zokusabalalisa ukukhanya kwensimu ye-diffraction ngezikhathi ezithile zingachazwa nge-grating diffraction theory. . Ngokulawula i-voltage esetshenzisiwe kungqimba oluyisisekelo ngokusho komthetho othile ukuze sithole ukusatshalaliswa komehluko wesigaba esihambisanayo, singakwazi ukulawula ukusatshalaliswa kokuphazamiseka kokukhanya kokukhanya endaweni ekude. Umphumela wokugxambukela uwukukhanya okunamandla kakhulu okuhamba ngakunye ohlangothini oluthile, kuyilapho amaza okukhanya aphuma kumayunithi okulawula isigaba kwezinye izikhombisi-ndlela akhansela amanye ngaphandle, ukuze kubonakale ukuskena kokuchezuka kwebhamu yokukhanya.

I-Optical Waveguide Phased Array Ngokusekelwe ku-Thermo-Optical Effect

Ikristalu’s thermo-optical effect ibhekisela kwinto yokuthi ukuhlelwa kwamangqamuzana ekristalu kushintshwa ngokushisisa noma ukupholisa ikristalu, okubangela ukuthi izici zokukhanya zekristalu zishintshe ngokushintsha kwezinga lokushisa. Ngenxa ye-anisotropy ye-crystal, umphumela we-thermo-optical unokubonakaliswa okuhlukahlukene, okungase kube ukuguqulwa kobude be-semi-axis ye-indicatrix, noma ukuguqulwa kwe-optical axis angle, ukuguqulwa kwendiza ye-optical axis, ukujikeleza kwe-indicatrix, njalonjalo. Njengomphumela we-electro-optical, umphumela we-thermo-optical wenza ithonya elifanayo ekuphambukeni kwe-beam. Ngokushintsha amandla okushisa ukuze kushintshwe inkomba esebenzayo ye-refractive ye-waveguide, ukuchezuka kwe-engeli ngakolunye uhlangothi kungafinyelelwa. Umfanekiso 2 uwumdwebo oyisikimu we-optical waveguide phased array ngokusekelwe kumthelela we-thermo-optical. Uhlu olunezigaba aluhlelwanga ngendlela efanayo futhi luhlanganiswe kudivayisi ye-CMOS engu-300mm ukuze kuzuzwe ukuchezuka kokuskena kokusebenza okuphezulu.
