Abstract
A new fiber-optic signal processor is proposed to implement systolic matrix–vector multipliers and lattice filters. 109 multiplications/sec can be achieved with currently available components for matrix–vector multiplications that involve Toeplitz matrices. A 2 × 2 (Toeplitz) matrix–vector multiplier has been experimentally demonstrated using single-mode fibers and directional couplers. The filtering characteristics of the device are also discussed.
