摘要

提出了一种自动校准调谐的微波硅光子环谐振器。由于工艺变化，环形谐振器的初始响应严重失真。通过在环内嵌入可调谐耦合器(Mach-Zehnder干涉仪(MZI))和基于光电探测器(PD)的监测器，开发适当的自动调谐算法，重建了自由频谱范围(FSR)为50 GHz的环的期望微波频率响应，并对其谐振频率进行了调谐。射频测量显示通过调整ORR可消除10 GHz和20 GHz信号。

Automatic Tuning of Microwave Silicon Photonic Ring Resonators

This paper presents an automatically calibrated and tuned microwave silicon photonic ring resonator. Due to process variations, the initial response of the ring resonator is severely distorted. By embedding a tunable coupler (Mach-Zehnder interferometer (MZI)) and a photo-detector (PD)-based monitor within the ring, and developing a proper automatic tuning algorithm, the desired microwave frequency response of the ring with free spectral range (FSR) of 50 GHz is reconstructed and its resonance frequency is tuned. RF measurements show cancellation of10 and 20 GHz signals by tuning the ORR.
