We propose a coherent multi-dimensional (wavelength, spatial mode, polarization, etc.) photonic tensor accelerator capable of matrix-vector, matrix-matrix, and batch matrix multiplications in a single clock cycle. A proof-of-concept $2\times2$ matrix-matrix multiplication at 25GBd with 4.67 bit precision was experimentally demonstrated.
