Calculates the cumulative nonlinear phase shift for a user-defined series of fiber sections.
How It Works
The total B-Integral is the sum of the B-Integrals of each individual fiber section:
B_total = Σ B_i
For each section, the calculation is:
B = (2π / λ) * n₂ * (P_peak_in / A_eff) * L_eff
- Peak Power:
P_peak = P_avg / (T_pulse * f_rep) - Effective Area:
A_eff = π * (MFD / 2)² - Effective Length (handles gain):
L_eff = L * (G - 1) / ln(G)
