Abstract bend waveguide section.

Based on AnalyticWaveguideModel.

Args

  • radius: Bend radius.
  • angle: Bend angle.
  • n_eff: Effective refractive index (loss can be included here by using complex values).
  • n_group: Group index. If None, the value of n_eff is used.
  • reference_frequency: Reference frequency dispersion coefficients.
  • propagation_loss: Propagation loss.
  • extra_loss: Length-independent loss.
  • dispersion: Chromatic dispersion coefficient.
  • dispersion_slope: Chromatic dispersion slope.
  • dn_dT: Temperature sensitivity for n_eff.
  • dL_dT: Temperature sensitivity for propagation_loss.
  • temperature: Operating temperature.
  • reference_temperature: Reference temperature.
