photonforge.parametric.s_bend_straight_coupler(*, port_spec=None, coupling_distance=None, s_bend_length=None, s_bend_offset=None, euler_fraction=None, coupling_length=None, technology=None, name=None, tidy3d_model_kwargs=None)[source]

S bend/straight coupling region.

Parameters:

  • port_spec (Annotated[str | PortSpec, _Metadata(type=PortSpec, title=None, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | Annotated[Sequence[Annotated[str | PortSpec, _Metadata(type=PortSpec, title=None, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)]], _Metadata(type=None, title=None, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=2, max_items=2)] | None) – Port specification describing waveguide cross-section. A tuple with 2 values can be used, one for each coupler side.

  • coupling_distance (Annotated[float, _Metadata(type=None, title=None, description=None, units=μm, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Distance between waveguide centers.

  • s_bend_length (Annotated[float, _Metadata(type=None, title=None, description=None, units=μm, required=False, minimum=None, maximum=None, exclusive_minimum=0, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Length of the S bends.

  • s_bend_offset (Annotated[float, _Metadata(type=None, title=None, description=None, units=μm, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Offset of the S bends.

  • euler_fraction (Annotated[float, _Metadata(type=None, title=None, description=None, units=None, required=False, minimum=0, maximum=1, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Fraction of the bends that is created using an Euler spiral (see photonforge.Path.arc()). If None, defaults to 0.

  • coupling_length (Annotated[float, _Metadata(type=None, title=None, description=None, units=μm, required=False, minimum=0, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Length of straight coupling region. If None, defaults to 0.

  • technology (Annotated[Technology, _Metadata(type=None, title=None, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Component technology. If None, the default technology is used.

  • name (Annotated[str, _Metadata(type=None, title=None, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Component name.

  • tidy3d_model_kwargs (Annotated[dict[str, Any], _Metadata(type=required, title=False, description=None, units=None, required=False, minimum=None, maximum=None, exclusive_minimum=None, exclusive_maximum=None, min_items=None, max_items=None)] | None) – Dictionary of keyword arguments passed to the component’s photonforge.Tidy3DModel.
