论文摘要

在最近的过去,Microwave Photonics(MWP)采用了许多重要的概念和技术,包括光子整合,多功能可编程性以及增强关键射频性能指标(例如噪声图和动态范围)的技术。但是,迄今为止,这些方面尚未在单电路中同时实现。在这里,我们首次证明了一个多功能集成的微波光子电路,该电路可以实现芯片可编程的过滤功能,同时实现了> 120 db.hz动态范围的创纪录高键射频指标和15 dB的噪声图,这些噪声图是以前无法实现的。我们通过使用所有集成调制变压器和双注射环谐振器作为多功能的光学滤波组件来通过多功能调制变压器和双注射环谐振器来解锁这一独特的功能。这项工作破坏了当前阻止在实际应用中采用集成的MWP系统的集成,功能和性能的传统和分散的方法。

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.
