Abstract

We demonstrate all optical matrix-matrix multiplication using nonlinear wave mixing in a PPLN waveguide, processing inputs, weights, and outputs entirely in the optical domain. The system supports reconfigurable matrix sizes ( and ) and operates at 3 and 5 GHz with \~{}4.6-bit precision. 2025 The Author(s)
