Summary: 
Optical signal processors consisting of integrated collinear acousto-optic modulators are proposed. In this device, wavelength-multiplexed optocal signals can be dealed with independently to each other by frequency-multiplexed surface acoustic waves. As applications to optical computing, several architectures performing matrix-vector and matrix-matrix multplications are discussed. Twos-complement arithmetic is also employed to improve accuracy and to handle bipolar numbers. The processing rate of matrix-vector multiplication is estimated to be 51010 and 3108 multiplication/sec. for analog and binary representations, respectively.
