| Abstract: | The operating mode in Lithium Niobate anisotropic acousto-electro-optic(AEO) device are determined,the geometrical relationships of anomalous acousto-optic interaction are gained by tangent condition and matching condition.The accurate angle of incident light vector,diffractive light vector and optic wave vector,acoustic extremum frequency and AO merit vs acoustic offaxis angle in xOz plane are systematically calculated and the results can be referenced for designing lithium niobate AEO device. |
