  Initiated by the analysis of phase relationship and by use of the films characteristic matrix expression, we deduced two implicit function expressions of the spacer moderate refractive index as well as P-polarization and S-polarization central wavelengths.Therefore, the value of moderate refractive index and corresponding central wavelength can be quickly and accurately obtained.Simulation calculations of two concrete filter designs for single cavity and three cavities prove that the method is feasible.We also proves that the algorithm is highly accurate though the examples data analysis of difference curves with incidence angle from 0° to 30°.

为满足传输容量不断增加的需要,WDM传输系统工作波段已由原来的C波段(1530~1565 nm)扩展到L波段(1565~1625 nm),工作波段的展宽对光纤通信器件提出了新的要求.为了对工作在C+L复合波段的WDM系统的色散进行补偿,并克服现有补偿光纤带宽窄、设计结构复杂不易于实现的缺点,设计了C+L波段的双包层色散补偿光子晶体光纤,并给出了补偿结果.该光纤包层结构为简单的三角形结构,材料为纯石
本文主要探讨的问题是光纤的曲率半径是否会对光纤的偏振模色散产生影响,偏振模色散作为光纤传输的一个重要指标,越来越受到人们的关注,在我们光缆生产过程中发现,出现偏振模色散(PMD)的光纤有很多是曲率超标,且是同一盘光纤(曲率超标)在不同的光缆中连续发生PMD超标,并且同一根光缆中其它光纤的PMD都合格,我们知道光纤弯曲会影响到PMD,那么曲率在什么情况下曲率会影响到偏振模色散(PMD)?针对此现象我

有机电致发光器件(OLED)由于在全色显示和固态照明方面的潜在应用,近年来受到了广泛关注,但其效率问题仍是被关注的热点.传统的平板OLED,由于有部分能量耦合成为表面等离子体(spp)后以热能的形式散失掉,而且存在器件内部波导的损耗,只有20%左右的光子能够出射.我们在器件内部用激光全息技术引入了周期性的一维光栅结构,通过光栅使spp再次以光子的形式出射,同时用光栅的调制作用来减少有机层造成的导波
变换光学是基于麦克斯韦方程组协变特性通过实施坐标变换来任意控制电磁波的全新理论。目前基于变换光学理论提出的电磁波分路设计方案都是在自由空间,仅提出了分路的概念,而上述方案都无法应用于实际的器件设计。本文通过实施沿轴向线性拉伸的嵌入式坐标变换方法来设计二维无反射的TM波分路器。由于通过变换光学理论计算出介质的介电常数和磁导率都各向异性,本文首先根据费马原理推导了各向异性介质分界面上的反射和折射定律,
