Waveguide bend section.

Args

  • port_spec: Port specification describing waveguide cross-section.
  • radius: Central arc radius.
  • angle: Arc coverage angle. If None, defaults to 90.
  • euler_fraction: Fraction of the bend that is created using an Euler spiral (see Path.arc). If None, defaults to 0.
  • port_bends: Flag controllig whether to set a bend radius for the ports. Not used when euler_factor > 0. If None, defaults to False.
  • technology: Component technology. If None, the default technology is used.
  • name: Component name.
  • model: Model to be used with this component. If None a WaveguideModel is used.

Returns

Component with the circular bend section, ports and model.

Example

>>> component = pf.parametric.bend(port_spec="Strip", radius=5, euler_fraction=0.5)
