On-chip generation and processing of high-power multi-GHz frequency combs

该项目旨在提供具有高功率和多GHz频率间隔的芯片级稳定光频梳技术。缺乏这种技术阻碍了需要高信噪比（SNR）梳的广泛应用的根本进步。该项目旨在展示使用波导激光器技术的梳，并将其与可重新配置的光学滤波器集成，以选择和处理单个梳线。该技术的主要优势包括高信噪比、可重构性、高稳定性、占地面积小和低成本，预计将提高天文学探测类地行星的能力，提高电信以增加整体互联网容量，以及全球定位系统（GPS）。

The project aims to deliver a chip-scale stable optical frequency comb technology with high-power and multi-GHz frequency spacing. The lack of this technology has prevented fundamental advances in wide-ranging applications that require high signal-to-noise-ratio (SNR) combs. The project seeks to demonstrate combs using waveguide laser technology and to integrate it with a reconfigurable optical filter to select and process individual comb lines. Key advantages of this technology, including high SNR, reconfigurability, high stability, small footprint and low-cost, are expected to improve astronomy’s ability to detect Earth-like planets, telecommunications to increase the overall internet capacity, and global positioning systems (GPS).
