Crystal LN-Q gbanwere
Nkọwa ngwaahịa
Ìhè ahụ na-agbasa na z-axis na mpaghara eletrik na-emetụta x-axis. Ọnụ ọgụgụ eletrọnịkị nke LiNbO3 bụ: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V na obere oge yana r33 = 31 pm/V, r31= 8.6 pm/V, r22 = V na elekere eletrik dị elu. Ọkara-ebili mmiri voltaji: Vπ = λd / (2no3r22L), rc = (ne / no) 3r33-r13.LiNbO3 bụkwa ezigbo kristal acousto-optic ma jiri ya mee ihe maka ụda ụda elu (SAW) wafer na AO modulators. CASTECH na-enye kristal acoustic (SAW) ọkwa LiNbO3 na wafers, boules ndị a kpụrụ akpụ, ihe ndị emechara na ihe ndị emebere.
