【摘要】 近年来出现了新的光学器件和新的光学理论—光子晶体。用光子晶体做成的光子集成芯片,可以像集成电路对电子的控制一样对光子进行控制,从而实现全光信息处理,在全光通信网、光量子信息、光子计算机等诸多研究领域有着诱人的应用前景。 研究光子晶体光学传输特性的方法有多种,传输矩阵法是一种简单实用的理论计算方法,将光子晶体作为整体来研究,不需讨论其中间环节,而且不用给出入射场的分布即可计算出光子晶体透射系数和反射系数。 本文研究了一维光子晶体带结构的优化设计,对光子晶体的传输特性进行了仿真,讨论了填充率对禁带宽度的影响和入射角对传输特性的影响等:重点研究了周期结构和缺陷层结构一维光子晶体波分复用滤波器的滤波特性。对于周期结构研究了叠层结构和3单元结构,引入理想因子,通过理想因子讨论参数的变化对多通道滤波特性的影响;设计了8信道波分复用(WDM)光子晶体滤波器。对于非周期结构,研究了单层缺陷结构和周期缺陷结构。讨论不同参数的变化对光子晶体多通道滤波特性的影响;设计了密集型波分复用光子晶体滤波器。更多还原

【Abstract】 Recently it appears new optical apparatus and new optical theory-photonic crystals. Photon integrated chip consisting of photonic crystals control photon as integrated circles control electron, then realize all optical information treatment. There are attracting future on all optical communication network, optic quanta information, photon computer field.There are many methods studying on photonic crystal, Transfer matrix method is a simple and utility theory calculate method, Study photonic crystals as integration don’t discuss intermediate process, and don’t show the distributing of incidence field can calculate the transmission and reflection of photonic crystals.This paper study the optimization design of one dimensional photonic crystals ,and simulate the transmission properties, discuss the influence of filling factor on width band and the influence of incidence angle on the transmission characteristic and so on, For the period structure, it study the structure of napped and three-unit complex period photonic crystals, introducing a parameter called perfect factor, discuss the influence of variational parameter on multi-channel filtering properties;and design 8 channel wavelength division multiplexing filter. For non-period structure, studying the structure of single layers and period layers. Discussing the influence of different parameter on multi-channel filtering properties. Finally, design the dense wavelength division multiplexing transmission filter.更多还原
