Silicon Photonic-Based Microwave Photonic Signal Processing

Abstract

Silicon photonics has emerged as a promising platform for integrating photonic and electronic functionalities on a single chip, enabling efficient signal processing across various domains including microwave photonics. This paper explores the advancements, applications, and challenges of silicon photonic-based microwave photonic signal processing (SiPh-MWPSP). It begins with an overview of the fundamentals of silicon photonics and microwave photonics, followed by a detailed discussion on the integration of these fields. Key components such as modulators, filters, and switches are analyzed for their role in SiPh-MWPSP systems. Furthermore, recent research achievements, future prospects, and potential applications in communication, radar, and sensing systems are reviewed. The paper concludes with a summary of current challenges and possible directions for future research in this rapidly evolving field.
