摘要
波长分束器是全光通信领域中至关重要的元器件。为满足日益复杂的微纳器件的设计要求,提出将有限元方法和移动渐近算法、材料插值法结合,形成了一种适应于微纳光子器件设计、计算速度更快、计算量更小的新逆设计智能算法,这种算法可根据设计者给定的目标函数来完成优化设计,对设计者的专业要求低,适应范围广。基于这一算法,成功地设计出尺寸为2μm×2μm、适用于片上集成的三通道波长分束器。三通道的信号透过率分别为47.5%、53.4%和52.5%,消光比为36、9.6和20。为微纳器件的设计提供了一种新的思路和借鉴。
Wavelength beam splitter is one of core components in the field of optical communication.In order to meet the design requirements of increasingly complex micro-nano devices,a new intelligent inverse design method which combining the Finite Element Method(FEM)with the Method of Moving Asymptotes(MMA)and the Material Interpolation Method(MIM)has been presented,which has a faster calculating speed and a lower arithmetic complexity,and adapt to the micro-nano photon devices design.This algorithm can complete the optimal design according to the objective function given by the designer,with low professional requirements for designers and wide range of adaptations.Based on this algorithm,a three-channel chip-integrated wavelength beam splitter with footprint of 2μm×2μm is successfully designed.Its transmission rates of the three channels are 47.5%,53.4%and 52.5%,respectively,and the extinction ratios are 36,9.6 and 20.Which provides a new idea and reference for design of micro-nano devices.
