Abstract

We have studied the matrix-vector and matrix-matrix multiplication using four-wave mixing in LiNbO3:Fe crystal. The response time of the device is in the order of a few seconds. The intensities representing the elements of matrices can be lower than 100μW/mm2. "We have also discussed two photorefraotive effects that affect the accuracy of multiplication.
