摘要：

We propose and demonstrate a modified-signed-digit (MSD) arithmetic to achieve multi-input digital optical computing. Our approach utilizes hybrid addition-subtraction transformation (or weight operation) rules among multiple inputs. This results in operation speeds that exceed those of two-input MSD arithmetic for multi-input computing. Optical implementation of the proposed multi-input MSD arithmetic by utilizing spatial data encoding and an optical fan-out element is also presented and experimentally demonstrated.
