Struct Birefringence 

pub struct Birefringence<'a> {
    pub section_km: f64,
    pub rotations: &'a [[C64; 4]],
    pub dgd_s_per_km: &'a [f64],
}

The birefringence of a span cut into sections of equal length (the PMD of comnum_channel::optical::pmd::PmdLink): section $k$ starts with the frequency-independent rotation rotations[k] (a row-major 2 × 2 matrix applied to $(A_{x}, A_{y})$) and then delays the two polarisations of its frame by $\mp \tau’{k} z / 2$, its DGD per kilometre dgd_s_per_km[k] distributed along it. Without nonlinearity a span is the lumped response $\prod{k} D_{k}(\omega) R_{k}$, $D_{k}$ the DGD of the whole section.

Fields

section_km: f64

The length of a section (km).

rotations: &'a [[C64; 4]]

The rotation at the start of every section.

dgd_s_per_km: &'a [f64]

The DGD of every section per kilometre (s/km).
