Optical and optoelectronic neuromorphic devices based on emerging memory technologies.

Traditional computing architectures face significant bottlenecks when handling massive datasets required by modern artificial intelligence. The separation of processing units from memory storage creates inherent delays in data transfer speeds. This physical distance limits overall energy efficiency and computational throughput in standard systems. Researchers have long sought alternative designs to overcome these fundamental hardware constraints. Neuromorphic computing offers a promising paradigm by mimicking biological neural structures for information processing. Emerging memory technologies provide the physical foundation for these novel hardware configurations. No prior work had fully resolved how to integrate photonic capabilities into these memory-based systems. That uncertainty drove the exploration of light-assisted processing to enhance current computational performance.
