摘要

为了满足日益增长的高频和宽带无线通信需求，将微波频率扩展到毫米波范围是必不可少的。微波光子滤波器作为微波光子系统的关键部件，用于选择目标信号和减少信道干扰。然而，由于电光器件和光学滤波器的带宽有限，实现40 GHz以上调谐范围的mpf仍然具有挑战性。在这项研究中，我们展示了一种基于绝缘体上铌酸锂薄膜平台的可重构集成MPF。MPF实现了2至62 GHz的最宽工作范围和0.7至3 GHz的可调频率分辨率。此外，该滤波器支持高频无线通信中Gbit/s数据速率的信道选择，为未来的应用提供实用且可扩展的解决方案。

Ultra-Wideband Tunable Thin-Film Lithium-Niobate-on-Insulator Microwave Photonic Filter

To meet the growing demand for high-frequency and broadband wireless communications, extending microwave frequencies to the millimeter-wave range is essential. Microwave photonic filters (MPFs), as key components in microwave photonic systems, are used to select target signals and reduce channel interference. However, achieving MPFs with a tuning range beyond 40 GHz remains challenging due to the limited bandwidth of electro-optical devices and optical filters. In this study, we demonstrate a reconfigurable integrated MPF based on a thin-film lithium-niobate-on-insulator platform. The MPF achieves the widest operational range from 2 to 62 GHz and a tunable frequency resolution from 0.7 to 3 GHz. Additionally, the filter enables channel selection for Gbit/s data rates in high-frequency wireless communication, offering a practical and scalable solution for future applications.
