Itekhnoloji ye-Optical phased array luhlobo olutsha lwetekhnoloji yokulawula ukuphambuka kwe-beam, enenzuzo yokuguquguquka, isantya esiphezulu kunye nokuchaneka okuphezulu.

Okwangoku, uninzi lophando lukwi-optical phased array ye-liquid crystal, optical waveguide, kunye ne-microelectromechanicalsystem (MEMS). Into esiyizisa kuwe namhlanje yimigaqo ehambelanayo yoluhlu lwe-optical phased optical waveguide.

I-optical waveguide phased array ikakhulu isebenzisa i-electro-optical effect okanye i-thermo-optical effect ye-dielectric material ukwenza umqadi wokukhanya ujike emva kokudlula kwizinto eziphathekayo.

Umphumo we-electro-optical we-crystal kukusebenzisa intsimi yombane yangaphandle kwi-crystal, ukwenzela ukuba i-beam yokukhanya edlula i-crystal ivelise ukulibaziseka kwesigaba esinxulumene nentsimi yangaphandle yombane. Ngokusekwe kwisiphumo sokuqala se-electro-optical yekristale, ukulibaziseka kwesigaba okubangelwa yintsimi yombane kuhambelana nombane osetyenzisiweyo, kwaye ukulibaziseka kwesigaba sokukhanya okudlula kumbindi we-optical waveguide kunokutshintshwa ngokulawula amandla ombane umaleko we-electrode ye-optical waveguide core nganye. Kuluhlu olucwangcisiweyo lwe-optical waveguide kunye ne-N-layer waveguide, umgaqo uboniswe kuMzobo 1: ukuhanjiswa kwemiqadi yokukhanya kwinqanaba ngalinye elingundoqo linokulawulwa ngokuzimeleyo, kunye neempawu zokusabalalisa ukukhanya kwentsimi ye-diffraction zingachazwa nge-grating diffraction theory. . Ngokulawula i-voltage esetyenzisiweyo kwi-core layer ngokomgaqo othile wokufumana ukusabalalisa umehluko wesigaba esihambelanayo, sinokulawula ukusabalalisa ukuphazamiseka kokukhanya kokukhanya kwintsimi ekude. Isiphumo sokuphazamiseka sisibane sokukhanya okuphezulu kwicala elithile, ngelixa amaza okukhanya aphuma kwiiyunithi zolawulo lwesigaba kwezinye izikhombisi arhoxisa enye kwenye, ukuze kuqatshelwe ukuskena kokuphambuka kwesibane sokukhanya.

I-Optical Waveguide yeSigaba seArray esekwe kwi-Thermo-Optical Effect

Ikristale’Impembelelo ye-thermo-optical ibhekisela kwinto yokuba i-crystal ilungiselelo le-molecular iguqulwa ngokufudumeza okanye ukupholisa i-crystal, ebangela ukuba iimpawu ze-optical zekristale zitshintshe kunye nokutshintsha kweqondo lokushisa. Ngenxa ye-anisotropy ye-crystal, umphumo we-thermo-optical unezibonakaliso ezahlukeneyo, ezinokuthi zitshintshe ubude be-semi-axis ye-indicatrix, okanye utshintsho lwe-angle ye-optical axis, ukuguqulwa kwendiza ye-optical axis, ukujikeleza kwe-indicatrix, njalo njalo. Njengomphumo we-electro-optical, umphumo we-thermo-optical wenza impembelelo efanayo kwi-deflection ye-beam. Ngokutshintsha amandla okufudumeza ukutshintsha isalathisi esisebenzayo se-refractive ye-waveguide, ukuphambuka kwe-angle kwelinye icala kunokufezekiswa. Umzobo we-2 ngumzobo weskimu we-optical waveguide phased array esekelwe kwimpembelelo ye-thermo-optical. Uluhlu olunezigaba alucwangciswanga ngokulinganayo kwaye ludityaniswe kwisixhobo se-CMOS esiyi-300mm ukuphumeza ukuphambuka kokuskena kokusebenza okuphezulu.
