Sparse coherent photonic processor for solving eigenmode problems
Zheyuan Zhu, Andrew B. Klein, Dewan Saiham, Guifang Li, Shuo Pang · 2023
We present a photonic processing primitive based on coherent mixing with high-speed programmable electronic interface for sparse matrix-vector multiplications. The precision of the photonic primitive is sufficient for solving waveguide eigenmodes, which has been verified on an FPGA emulator of the primitive.
