Abstract

A generic antenna array design approach through multi-objective optimization is adopted to design a non-uniform optical thinned array (TA) satisfying a desired far-field pattern mask and minimizing the number of radiating elements. The proposed optical TA is integrated with a silicon photonic beam-forming network (BFN) made of a mesh of tuneable Mach-Zehnder interferometer to implement a self-adaptive beam transmitter/receiver for free-space optical (FSO) systems. Experimental results demonstrate the beam steering and shaping capability of the proposed architecture, which self-configures without any need for pre-calibration.

由集成光子处理器控制的自适应光学稀化天线阵列

本文采用多目标优化的通用天线阵列设计方法，设计出一种非均匀光学稀疏阵列（TA），既能满足所需的远场模式掩码，又能最大限度地减少辐射元件的数量。所提出的光学薄化阵列与由可调马赫-泽恩德干涉仪组成的硅光子波束形成网络（BFN）集成，为自由空间光学（FSO）系统实现了自适应波束发射器/接收器。实验结果证明了拟议架构的光束转向和整形能力，该架构无需预先校准即可进行自配置。

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.
