Description
Summary:According to the three-layer structure model of fiber and the theory of fiber coupling mode, the mode coupling characteristics of LPFG are deduced and simulated by MATLAB. The LPFG transmission spectrum obtained by simulation is basically consistent with the existing experimental results. In addition, by changing the input parameters, the transmission spectra of different LPFG can be simulated, which is of great value for theoretical research and parameter design in practical application of LPFG.
