LN–Q Beddelka Crystal
Sharaxaada Alaabta
Iftiinku wuxuu ku faafaa dhidibka z-axis iyo goobta korantada waxay khuseysaa dhidibka x. Isku dhafka elektiroonigga ah ee LiNbO3 waa: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V inta jeer ee hooseeya iyo r33 = 31 pm/V, r31= 8.6 pm/V, r22 = 3.4 pm/V inta jeer ee korontadu sarayso. Korantada kala badh-mawjadda: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 sidoo kale waa crystal acousto-optic wanaagsan oo loo isticmaalo mowjad acoustic ah dusha sare (SAW) wafer iyo modulators AO. CASTECH waxay bixisaa kiristaalo acoustic (SAW) darajada LiNbO3 ee maraqyada, boules sida-la jarjaray, qaybaha la dhammeeyey iyo walxaha la sameeyay.
