片上滤波器仿真数据集

本数据集源于4阶FIR滤波器光谱响应仿真，背景为满足可编程片上滤波器性能评估需求，旨在理论研究其在中心波长、带宽、消光比及滤波形状的可调谐能力和光预均衡能力。数据集主要面向片上滤波器设计、光谱响应分析研究，基于4阶FIR滤波器传输函数模型仿真生成。产生方法上，设定固定时间延时10ps（对应FSR=100GHz/0.8nm）、光速常量，波长仿真范围1549nm–1551nm，通过调控幅度加权系数与相位加权系数实现不同仿真：中心波长调谐采用“固定幅度、相位加等差数列”方式，带宽与消光比调谐通过for循环遍历参数组合，滤波形状调谐利用幅频响应余弦项特性调整参数。主要内容为单一层级存储的.mat格式文件，含CW.mat（中心波长）、OBW.mat（3dB 带宽）等6类，记录各个波长（nm）对应的插损（dB）变化。各文件列数2–4列不等，整体数据按仿真场景分类，方便取用，数据量为165K。This dataset is derived from spectral response simulations of a 4th-order FIR filter, developed to meet the demand for performance evaluation of programmable on-chip filters, and aims to conduct theoretical investigations into its tunability in central wavelength, bandwidth, extinction ratio, and filter shape, as well as its optical pre-emphasis capability. It is primarily targeted at on-chip filter design and spectral response analysis research, and is generated through simulations based on the transfer function model of the 4th-order FIR filter. For the generation method, a fixed time delay of 10 ps (corresponding to FSR=100 GHz/0.8 nm) and the speed of light constant are configured, with the wavelength simulation range set from 1549 nm to 1551 nm. Various simulations are realized by adjusting amplitude weighting coefficients and phase weighting coefficients: central wavelength tuning uses the approach of "fixed amplitude, phase plus arithmetic sequence"; bandwidth and extinction ratio tuning is implemented by traversing parameter combinations via for loops; filter shape tuning is achieved by modifying parameters using the cosine term characteristics of the amplitude-frequency response. The core content comprises MATLAB .mat format files stored in a single-level hierarchy, including 6 categories such as CW.mat (central wavelength) and OBW.mat (3 dB bandwidth), which record the insertion loss (dB) values corresponding to each wavelength (nm). Each file contains 2 to 4 columns with varying column counts, and the overall dataset is categorized by simulation scenarios for easy access, with a total dataset size of 165K.
