Abstract
Future neuromorphic computing seeks to transcend the limitations inherent in von Neumann architectures by integrating sensing, storage, and computation. Emerging as the preferred framework for advanced AI systems, non-von Neumann architectures present a viable alternative. Moreover, all-optical modulated memristors are a promising avenue for the evolution of innovative memory computing technologies. This study introduces and validates an all-optical, controllable, high-density memory element embedded within a vanadium dioxide (VO₂)-based seven-core optical fiber. By utilizing a pulsed laser with an average power requirement of merely 0.5 mW, our optical modulation scheme ensures stable, repeatable switching operations and achieves eight distinct levels of data storage (21 bits). This optical fiber memory device exhibits substantial optical contrast (~45%) and facilitates all-optical logic functions, including "AND" and "OR" operations. The advanced optical fiber showcased in this research holds significant potential for optical network applications, heralding a new paradigm in bio-inspired sensing and computational processes.
