Nanoelectronics research center imec of Leuven, Belgium and two imec research groups at Ghent University (the Photonics Research Group and IDlab) have demonstrated a fully integrated single-chip microwave photonics system, combining optical and microwave signal processing on a single silicon chip (Hong Deng et al, ‘Single-chip silicon photonic engine for analog optical and microwave signals processing’ Nature Communications volume 16, Article number 5087 (2025)). The chip integrates high-speed modulators, optical filters, photodetectors and transfer-printed lasers, making it a compact, self-contained and programmable solution for high-frequency signal processing. This can replace bulky and power-hungry components, enabling faster wireless networks, low-cost microwave sensing, and scalable deployment in applications like 5G/6G, satellite communications, and radar systems...
