LN-Q Hloov Crystal
Product Description
Lub teeb propagates nyob rau hauv z-axis thiab hluav taws xob teb siv rau x-axis.Electro-optic coefficients ntawm LiNbO3 yog: r33 = 32 pm / V, r31 = 10 pm / V, r22 = 6.8 pm / V ntawm tsawg zaus thiab r33 = 31 pm / V, r31 = 8.6 pm / V, r22 = 3.4 pm/V ntawm high electric zaus.Qhov ib nrab-yoj voltage: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 kuj yog ib qho zoo acousto-optic siv lead ua thiab siv rau saum npoo acoustic yoj (SAW) wafer thiab AO modulators.CASTECH muab acoustic (SAW) qib LiNbO3 muaju nyob rau hauv wafers, as-cut boules, tiav cov khoom thiab kev cai fabricated hais.
