Abstract bend waveguide section.

Based on photonforge.AnalyticWaveguideModel.

Parameters:

  • radius (Annotated[float, minimum=0, units='μm']) – Bend radius.

  • angle (Annotated[float, units='°']) – Bend angle.

  • n_eff (complex) – Effective refractive index (loss can be included here by using complex values).

  • n_group (float | None) – Group index. If None, the value of n_eff is used.

  • reference_frequency (Annotated[float, minimum=0, units='Hz']) – Reference frequency dispersion coefficients.

  • propagation_loss (Annotated[float, minimum=0, units='dB/μm']) – Propagation loss.

  • extra_loss (Annotated[float, minimum=0, units='dB']) – Length-independent loss.

  • dispersion (Annotated[float, units='s/μm²']) – Chromatic dispersion coefficient.

  • dispersion_slope (Annotated[float, units='s/μm³']) – Chromatic dispersion slope.

  • dn_dT (Annotated[complex, units='1/K']) – Temperature sensitivity for n_eff.

  • dL_dT (Annotated[float, units='dB/μm/K']) – Temperature sensitivity for propagation_loss.

  • temperature (Annotated[float, minimum=0, units='K']) – Operating temperature.

  • reference_temperature (Annotated[float, minimum=0, units='K']) – Reference temperature.
