New integrated acousto-optic matrix algebra processor architecture

Abstract

A new integrated optic matrix algebra processor architecture that utilizes guided-wave multifrequency acoustooptic (AO) Bragg diffractions is proposed. The architecture is potentially capable of performing matrix-vector multiplications faster than any AO architecture reported heretofore, and matrix-matrix multiplications at rates comparable to the fastest bulk-wave AO architecture. An integrated AO processor module has been realilzed in a Y-cut LiNbO3 substrate 1.0×10.0×28.0 mm3 in size to demonstrate the multiplication of a 4×4 matrix with a 4-element vector at the optical wavelength of 0.6328 μm.
