Abstract	An integrated acoustooptic (AO) module that consists of a wideband AO Bragg cell, a wide-angle ion-milled concave Bragg grating lens, and a large-aperture titanium-indiffusion proton-exchange lens has been realized in a y-cut LiNbO/sub 3/ waveguide 1816 mm/sup 3/ in size and used to perform interferometric RF spectrum analysis. This module has provided a bandwidth of 205 MHz centered at 350 MHz and single-tone instantaneous and two-tone, third-order spurious-free dynamic ranges of 50 and 40 dB, respectively, at 1.0 mW of 0.6328- mu m laser power and a drive power of 50 mW per RF signal. A pair of such basic AO modules has been integrated in a common LiNbO/sub 3/ substrate 11016 mm/sup 3/ in size to facilitate measurement of the phase difference, and thus the angle of arrival, of RF signals.<>
