Abstract
Acousto-optic(AO) devices having a sectioned optical transducer with a side passing optical beam forming an acousto-optic interaction plane, an electrode pattern on the transducer, and oblique demarcation cuts in the electrode pattern which are not normal to the acousto-optic interaction plane. The oblique cuts are at an angle oriented between 5 to 85 degrees, preferably approximately 45 degrees, with respect to the normal to the acousto-optic interaction plane. The oblique demarcation cuts eliminate side-lobes and ghost images in an acoustic field generated by the transducer. The electrode pattern shapes can be diamond, a truncated Gaussian, cosine, square, rectangular, circular, and elliptical. Acousto-Optic Modulators (AOMs). The types of AO devices include: Acousto-Optic Beam Deflectors (AOBDs), Bragg Cells (BCs), Acousto-Optic Tunable Filters (AOTFs), Acousto-Optic Frequency Shifters (AOFSs), and Acoust-Optic Correlators (AOCs).
