中文摘要： 波束形成器件是相控阵雷达天线的核心器件，然而，现有的基于移相器以及光纤排布的波束形成器件受到体积及重量的限制，难以应用于星载及机载相控阵雷达，因此，波束形成网络的小型化甚至芯片化已成为该领域亟待解决的问题。申请者在前期研究中发现波导微环二叉树双环展宽结构波束形成网络器件具有体积小、延时精度高、易于芯片化集成的优点，可解决波束形成器小型化、芯片化的难题。本申请拟通过研究波导微环谐振腔模式理论，分析双环展宽结构波束形成网络延时特性，探索热电极形状等参数对光控波束形成器延时量、延时带宽、延时抖动等特性的影响机制及可控性，设计制备应用于相控阵雷达天线的集成光波导二叉树双环展宽结构光控波束形成芯片。本研究对光控波束形成芯片的研究具有重要理论意义以及实用价值，为其在机载及星载相控阵雷达天线的应用提供理论与实验基础。

英文摘要： Beam-Forming-Devices(BFD) are the core devices of the phased array radar antenna. However, the existing BFD based on the phase shifter and arrayed fiber can not be applied on the spaceborne and airborne phased array radar due to the size and the weight limitations.Therefore, the integrated BFD with small size, or even fabricated on chip scale is prefered. Depending on the early research of the microring resonator device, we proposed the binary tree micro-resonator can be adopted to design and fabricate Optical-Controlled-Beam-Forming-Network(OBFN) chip with the merits of low transmission loss, high precision, and can be integrated on chip. This project will investigate the mode theory of the microring resonator, analyze the delay characteristics of the double-ring structure OBFN, study the influence mechanism of the shape and thickness of the thermode on the transmission loss, delay time, delay bandwidth and delay jitter of the OBFN, design and fabricate the OBFN used in the spaceborne and airborne phased array radar. This research is of significantly theoretical and practical value on the microring resonator based OBFN, which will provide theoretical and experimental results on the binary tree microring resonator based OBFN which is used in the sapceborne and airborne phased array radar.
