Concentrating on a simple simulation of signal propagation across an optical fibre with the aid of the Split-Step Fourier Method (SSFM), we suggest a procedural direction to simulate an optical fiber model in MATLAB:

Procedural Instruction to Optical Fiber Simulation in MATLAB

Step 1: Define the System Parameters

Mainly, for the optical fiber and the signal, we plan to describe the metrics such as attenuation, nonlinearity, fiber length, input pulse characteristics, and dispersion.

Step 2: Implement the Split-Step Fourier Method

For resolving the nonlinear Schrödinger equation (NLSE), SSFM is employed which is considered as a numerical method. The propagation of optical pulses in fibers is designed through this approach.

Step 3: Simulate Signal Propagation

Through the utilization of the SSFM, our team focuses on propagating the signal and it is appreciable to visualize the outcomes.

beta2 = -2.17e-26; % Dispersion parameter in s^2/m

gamma = 1.3; % Nonlinearity coefficient in 1/(W*m)

lambda = 1550e-9; % Wavelength in meters

c = 3e8; % Speed of light in m/s

D = 1 / (lambda^2 * c) * beta2; % Dispersion in ps/(nm*km)

dz = 0.01; % Step size in km

% Pulse Parameters

T0 = 10e-12; % Pulse width in seconds (10 ps)

P0 = 1; % Peak power in W

t = -50e-12:0.1e-12:50e-12; % Time vector in seconds

% Initial Pulse Shape (Gaussian)

Step 2: Implement the Split-Step Fourier Method

% Convert attenuation to linear scale

alpha_linear = alpha / (10 * log10(exp(1)));

% Number of steps

num_steps = round(fiber_length / dz);

% Angular frequency vector

omega = 2 * pi * linspace(-1 / (2 * (t(2) – t(1))), 1 / (2 * (t(2) – t(1))), length(t));

% Fourier transform of the initial pulse

pulse_ft = fftshift(fft(pulse));

% Propagation Loop

for step = 1:num_steps

% Half-step linear propagation (dispersion)

pulse_ft = pulse_ft .* exp(-1i * (beta2 / 2) * omega.^2 * (dz / 2));

% Inverse Fourier transform to time domain

pulse = ifft(ifftshift(pulse_ft));

% Full-step nonlinear propagation

pulse = pulse .* exp(-1i * gamma * abs(pulse).^2 * dz);

% Fourier transform to frequency domain

pulse_ft = fftshift(fft(pulse));

% Half-step linear propagation (dispersion)

pulse_ft = pulse_ft .* exp(-1i * (beta2 / 2) * omega.^2 * (dz / 2));

% Attenuation
