NEW INTEGRATED ACOUSTOOPTIC MATRIX ALGEBRA PROCESSOR ARCHITECTURE

A new integrated optic matrix algebra processor architecture that utilizes guided-wave multifrequency acousto-optic (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 realized in a Y-cut LiNbO3 substrate 1.0 x 10.0 x 28.0 mm3 in size to demonstrate the multiplication of a 4X4 matrix with a 4-element vector at the optical wavelength of 0.6328-mu-m.
