Dec 10, 2015 · This script can calculates the LP modes for specific attributes of a fiber and draw them. Simply change the attributes like 'a' (diameter) or lambda and the script should do the rest.

Jun 30, 2020 · This library solves the eigenvalue equation for a step-index fibre under the weakly-guided, linear polarisation approximation, generating propagation constants and other parameters, including power in core, for each of the supported LP modes.

Defines a fibre, finds LP modes, plots all LP modes and displays example amplitude and intensity plots in figures. Generates a Gaussian input beam and couples into fibre. Generates plane waves at a range of angles and calculates coupling efficiency for each, comparing with geometric acceptance angle.

May 3, 2020 · MMF_simTM_LP computes the linearly polarized (LP) modes of a straight MMF with user defined fiber specification. The LP modes are the approximated PIMs under the weakly guiding modes condition. It also provides a TM of the MMF in …

May 19, 2021 · LP optical fiber modes 3D polar plot question On Matlab online it tells me to preallocate certain variables from the functions in the link below: https://www.mathworks.com/matlabcentral/fileexchange/9126-fiber-modes

fprintf('Estimating %d LP modes from V number. \n', round(est_num_modes(wavelength, coreRadius, nCore, nCladding) /2)); fprintf('Found %d LP modes (%d including rotations). \n', length(modes), nModes);

With the RP Fiber Power software, a wide range of properties of LP modes can be calculated. There are convenient Power Forms for cases with given refractive index profile or for germanosilicate fibers with given doping profile.
