Abstract

We propose two configurations for the coexistence of sensing and communication signals, exploiting Free Space Optical (FSO) links to transmit commercial 6G traffic and remotely interrogate sensors distributed along distances of 100 m. The sensors are fabricated on a Silicon Photonics (SiPh) platform, to achieve miniaturization and highly compact form of the required features. The first scheme consists of couplers and circulators, while the second utilizes polarization handling elements to multiplex both signals, while a 100-m outdoor Free Space Optical link is utilized for both schemes. The configurations exhibit high stability, with uninterrupted transmission of traffic along the duration of the experiments, while the sensors’ performance is evaluated, with their discrepancies measured below 2%.

用于6G部署的SiPh传感链路和超过100米FSO链路的真实世界流量共存

我们提出了传感和通信信号共存的两种配置，利用自由空间光（FSO）链路传输商业6G流量，并远程询问分布在100米距离上的传感器。传感器在硅光子学（SiPh）平台上制造，以实现所需功能的小型化和高度紧凑形式。第一种方案由耦合器和环行器组成，而第二种方案利用极化处理元件对两个信号进行多路复用，同时两种方案都利用了100米的室外自由空间光链路。该配置具有高稳定性，在实验期间流量传输不间断，而传感器的性能被评估，其差异测量在2%以下。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
