# ContainerWithRoundedWaveguides¶

class picazzo3.container.container_waveguides.ContainerWithRoundedWaveguides(*args, **kwargs)

Container with waveguides (picazzo3.container.container.ContainerWithWaveguides) which generates its waveguides from a given waveguide_template and routes. You can specify a bend radius and rounding algorithm for the waveguides in the Layout view.

Parameters: Other Parameters: trace_template: ( PCell and _WaveguideTemplate ), *None allowed* Template for all ports. If None, the waveguide templates of the ports will be used auto_transition: ( bool, bool_, bool or int ) If True, automatically transition all ports of contents to the given trace template. If False, no transitions are applied, which might lead to a discontinuity in the waveguide. Also, if trace_template is None, no transitions are applied. port_labels: ( List with type restriction, allowed types: ), *None allowed* Labels of the ports to be processed. Set to None to process all ports. contents: PCell the contents of the container: the child cell external_port_names: Dictionary for remapping of the port names of the contents to the external ports name: The unique name of the pcell trace_templates: List with type restriction, allowed types: , locked list of templates to apply to all ports waveguides: List with type restriction, allowed types: , locked

Views

Layout
Parameters: angle_step: float and number > 0 Angle step for rounding. manhattan: ( bool, bool_, bool or int ) Adds rectangular blocks in the bends to avoid as much as possible non-manhattan angles. view_name: str and ( Alphanumeric string or Contains _\$ ) The name of the view routes: routes along which the waveguides will be generated contents_transformation: GenericNoDistortTransform flatten_contents: ( bool, bool_, bool or int ) if True, it will insert the contents as elements in the layout, rather than as an Instance bend_radius: float and number > 0 Bend radius for the auto-generated bends. rounding_algorithm: Rounding algorithm used to generate the bends. Can be circular, spline, ….
