根据条形光波导折射率数据，分别针对宽高比a:b为1:1与 2:1两种情形，设计分析 ： 1. 满足单模与双模传输的 波导尺寸范围。（需要 给出色散曲线） 2. 针对两种情形，选取你 认为最佳的波导尺寸， 计算对应的模折射率。 （计算时假设上、下包 层均很厚）(According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and 2: 1 both cases, the design and analysis: 1. Meet single-mode and dual-mode transmission Bird size range. (need Given dispersion curve) 2. For both cases, you select That the best of the waveguide dimensions, Computes the corresponding mode refractive index. (Calculations assume that when the upper and lower package Layers are very thick))

巴特沃斯无源滤波器设计 内涵高通带阻带通低通四种类型的设计，其中低通参见本人上传的低通滤波器设计(Butterworth high-pass passive filter design content, low-pass band-stop four types of band-pass design, in which low-pass see my upload low-pass filter design)

该程序提供了多种参数的双指数脉冲函数的波形及其频谱分解图，要注意的是作图时坐标比例尺的调整。程序中给出的是1.2/50μs和0.7/60ns两种波形可直接使用的坐标比例尺。 在MATLAB5.0下就能工作。 (The program provides a wide range of parameters of double-exponential pulse function waveform and its spectral decomposition diagram, it should be noted that when mapping coordinates scale adjustments. Procedure is given in 1.2/50μs and 0.7/60ns two waveforms can be directly used the coordinates of scale. Will be able to work under in MATLAB5.0.)
