Abstract

A polarization sensitivity was observed in the bandwidth and interaction efficiency during the investigation of the SAW acousto-optic (AO) interaction in lithium niobate. It was observed that input light linearly polarized along the propagation direction of the acoustic beam allowed an increased interaction bandwidth when compared with input illumination polarized orthogonal to the acoustic propagation direction. The polarization of the optical beam remained unchanged to within one part in 10,000. Experimental findings show that this polarization sensitivity was parameterized by acoustic wavelength. Results of the wavelength parameterization are reported and comparisons drawn to theoretical work performed in the Johns Hopkins University study funded by Harry Diamond Laboratories.
