Functions

g2_split(n_eff, a_eff, chi2_eff)	The 2nd-order nonlinear parameter decomposed according to unit analysis.
g2_shg(v0, v_grid, n_eff, a_eff, chi2_eff)	The 2nd-order nonlinear parameter weighted for second harmonic generation centered around the given input frequency.
domain_inversions(z, dk[, n])	Find the location of the domain inversion boundaries that quasi-phase match (QPM) the given wavenumber mismatch.
