  1. ; ; ; (, IEEE)
    We designed and fabricated a CMOS-compatible polarization beam splitter and rotator purely in Si 3 N 4 , achieving experimentally an insertion loss of ~1.5dB and a polarization extinction ratio greater than 15dB from 1280 to 1320nm.

  2. ; ; ; ; ; (, Optica Publishing Group)
    A coherent multi-dimensional photonic tensor accelerator performing high-speed matrix-matrix multiplication is proposed and demonstrated. A pattern recognition experiment is demonstrated at a 25Gbps modulation speed exploiting orthogonal dimensions of light including time, wavelength, and spatial mode.

    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 2x2 matrix-matrix multiplication at 25GBd with 4.67 bit precision was experimentally demonstrated.
