超高动态范围低噪声可编程集成微波光子滤波器
Ultrahigh Dynamic Range and Low Noise Figure Programmable Integrated Microwave Photonic Filter
摘要：
微波光子学（MWP）在最近的过去已经采用了许多重要的概念和技术，包括光子集成、通用可编程性以及用于增强关键射频性能指标（诸如噪声系数和动态范围）的技术。然而，迄今为止，这些方面还没有在单个电路中同时实现。在这里，我们首次展示了一种多功能集成微波光子电路，该电路可实现片上可编程滤波功能，同时实现了>120 dB.Hz动态范围和15 dB噪声系数的创纪录高关键射频指标，这是以前无法达到的。我们解锁这个独特的功能，通过多功能的复杂频谱剪裁使用一个全集成的调制Transformer和双注入环形谐振器作为多功能光学滤波组件。这项工作打破了传统的集成，功能和性能的分散方法，目前阻止了在实际应用中采用集成的MWP系统。
英文摘要：
Microwave photonics (MWP) has adopted a number of important concepts and technologies over the recent pasts, including photonic integration, versatile programmability, and techniques for enhancing key radio frequency performance metrics such as the noise figure and the dynamic range. However, to date, these aspects have not been achieved simultaneously in a single circuit. Here, we demonstrate, for the first time, a multi-functional integrated microwave photonic circuit that enables on-chip programmable filtering functions while achieving record-high key radio frequency metrics of >120 dB.Hz dynamic range and 15 dB of noise figure that are previously unreachable. We unlock this unique feature by versatile complex spectrum tailoring using an all integrated modulation transformer and a double injection ring resonator as a multi-function optical filtering component. This work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of integrated MWP systems in real applications.
