摘要

可重构光子滤波器是满足未来微波通信系统发展需求的一种潜在解决方案。通过将高性能滤波器集成到可编程微波光子处理器中,它们可以为信号处理应用提供显着的好处。为此,开发一种能够使用单个光输入和输出端口自动表征和重新配置滤波器的算法是必不可少的。本文提出了一种全可调谐环辅助马赫-曾德尔干涉仪滤波器的优化技术。所提出的滤波器设计消除了对监控组件的需要,并采用了一种新颖的算法,通过在滤波器的两个臂之间切换,在每个环中独立运行。此外,过滤器可以配置为实现不同的过滤器架构,从而允许灵活的过滤需求。使用该装置作为交织器进行测量,在光学和射频域实现不同类型的无限脉冲响应滤波器。通过重新配置相同的器件,实现了侧耦合集成间隔序列谐振器滤波器。这些结果证明了本文提出的滤波器设计在带宽和中心频率方面具有优异的可重构性。

Self-configuring programmable silicon photonic filter for integrated microwave photonic processors
Reconfigurable photonic filters show great promise as a potential solution to meet the evolving needs of future microwave communication systems. By integrating high-performance filters into programmable microwave photonic processors, they can provide significant benefits for signal processing applications. The development of an algorithm that can automatically characterize and reconfigure the filter using a single optical input and output port is essential for this purpose. This paper presents an optimization technique for a fully tunable ring-assisted Mach–Zehnder interferometer filter. The proposed filter design eliminates the need for monitoring components and employs a novel algorithm that operates independently in each ring by switching between the two arms of the filter. In addition, the filter can be configured to implement different filter architectures, allowing for flexible filtering requirements. Measurements were performed using the device as an interleaver, implementing different types of infinite impulse response filters in the optical and radio frequency domains. Side-coupled integrated spaced sequence of resonator filters were also implemented by reconfiguring the same device. These results demonstrate the exceptional reconfigurability of the filter design proposed herein in terms of bandwidth and central frequency.
