| 摘 要： | 通过有限差分波束传播法(FD-BPM)研究了N×N平面波导型星型耦合器的优化设计思想和方法,并通过17×17星型耦合器的模拟设计证明了它的可行性.给出了在输出端引入辅助波导的方法,以提高输出波导阵列的均匀性.并通过模拟计算,分析了圆心缩入程度和锥形区的形状对输出结果的影响.此法也同样适合于N值更大的星型耦合器.

| Abstract: | A large-scale N×N planner star coupler is a key component of a high-speed,multi channel optical network.The method for optimizing the planner star coupler is researched by using the finite difference beam propagation method(FD-BPM),and its feasibility is verified by applying it to a 17×17 star coupler.The paper presents a method to improve the uniformity of the output energy from the wave-guide array by introducing some assistant wave-guides.The effects of the recess distant and the tapers′shape on the result are also analyzed.This approach can be also efficient in the simulations of optical networks with a larger N. |
