Polarization measurement has been widely used in materials characterization. Conventional polarization analyzers (PA) based on free-space components are often bulky and require a stable platform. Taking advantage of silicon photonics, photonic integrated circuits for PA have been developed recently. In this letter, we propose and demonstrate an ultra-compact PA using a micro-ring modulator (MRM)-assisted interferometer with a chip size of ~0.12mm ² . The fabricated devices show robust performance with measurement accuracy of ±2.3%.

基于微环谐振器的超紧凑型偏振分析仪

偏振测量已广泛用于材料表征。基于自由空间组件的传统偏振分析仪 (PA) 通常体积庞大且需要稳定的平台。利用硅光子学，最近开发了用于 PA 的光子集成电路。在这封信中，我们提出并演示了使用微环调制器 (MRM) 辅助干涉仪的超紧凑 PA，其芯片尺寸约为 0.12mm ² 。制造的设备显示出稳定的性能，测量精度为 ±2.3%。
