Title

"Analog Information Processing with Programmable Photonic Circuits"

Abstract

Analog photonic information processing is garnering significant interest due to its potential to revolutionize how we approach signal processing. Unlike digital systems, analog
photonic processors can naturally leverage the inherent properties of light to perform complex computations with exceptional speed and efficiency. In this talk, I will present a novel programmable photonic circuit architecture for efficiently implementing arbitrary matrix-vector multiplications—one of the most fundamental mathematical operations that underpin a wide range of applications. I will explore the key features of this architecture, which leverages alternating active and passive building blocks, and discuss its extensions for realizing essential transformations in information processing. Additionally, I will highlight its applications in photonic devices, spanning switching, filtering, and beam steering.

Looking ahead, I will outline a roadmap for integrating these capabilities into on-chip photonic neural networks. I will conclude by discussing the key challenges and opportunities of programmable photonic alternating architectures for advancing photonic computing.
