Photonic tensor core for machine learning: a review

Abstract: Photonic Tensor Core circuits have been widely explored as possible hardware accelerators for the next generation of Machine Learning applications, due to the large bandwidth, low latency, and energy saving that light has. Many architectures have been presented, especially exploiting photonic integrated circuits. However, most of the proposed solutions lack some features, such as integration, scalability, or energy saving. In this paper, we review the major achievements in recent years, showing how high integr… Show more

“…Such an enhanced FSR device holds potential applications in chemical sensing, all-optical wavelength division multiplexed networks, tunable filters or switches, biomolecule sensing, and environmental monitoring. 18 The proposed structure can also be significantly applicable in photonic neural networks (PNN) where micro-ring resonators function as weights 19 and can exhibit nonlinear activation properties. 20 Thus, by varying various device parameters, the weights of the PNN can be actively changed, hence by enhancing the performance of the PNN.…”

“…Nonetheless, advancements in technology have highlighted several shortcomings of DMDs in both research and commercial applications, including issues in terms of size and weight, flexibility, and efficiency. Compared to other proposed on-chip integrated photonic hardware accelerators and in-memory computational photonic tensor cores, all-optical convolution solutions offer an alternative approach with a higher data processing rate and lower power consumption [ 5 , 6 , 7 , 8 , 9 ]. A 4f-type optical system has been utilized to introduce a method for optical matrix multiplication.…”
