A new technical paper titled “A Case Study on the Performance Metrics of Integrated Photonic Computing” was published by researchers at IBM Research – Europe, University of Heidelberg and University of Münster.
Abstract
“Photonic processors use optical signals for computation, leveraging the high bandwidth and low loss of optical links. While many approaches have been proposed, including in memory photonic circuits, most efforts have focused on the physical design of photonic components rather than full architectural integration with electronic peripheral circuitry. In this work, we present a microarchitecture level study that estimates the compute efficiency and density of three prominent photonic computing architectures. Our evaluation accounts for both the photonic circuits and the essential peripheral electronics required for optoelectronic and analog to digital conversions. We further demonstrate a heterogenous photonic electronic in memory processing approach for low latency neural network inference. These results provide a better understanding of the design aspects of photonic computing.”
