jj_manhattan

class jj_manhattan(design: QDesign, name: str = None, options: Dict = None, make=True, component_template: Dict = None)

The base “JJ_Manhattan” inherits the “QComponent” class.

NOTE TO USER: Please be aware that when designing with this qcomponent, one must take care in accounting for the junction qgeometry when exporting to to GDS and/or to a simulator. This qcomponent should not be rendered for EM simulation.

This creates a “Manhattan”-style Josephson Junction consisting of two overlapping thin metal strips, each connected to a larger metallic pad region.

Default Options:

• JJ_pad_lower_width: ‘4um’ – width of lower JJ metal region

• JJ_pad_lower_height: ‘2um’ – height of lower JJ metal region

• JJ_pad_lower_pos_x: ‘0’ – the initial x-coord of the lower rectangle

• JJ_pad_lower_pos_y: ‘0’ – the initial y-coord of the lower rectangle

• finger_lower_width: ‘1um’ – the width of the overlapping rectangular finger(s)

• finger_lower_height: ‘20um’ – the length of the overlapping rectangular finger(s)

• extension: ‘1um’ – the length of the fingers extending beyond the cross-point

Create a new Metal component and adds it’s default_options to the design.

Parameters:

• design (QDesign) – The parent design.

• name (str) – Name of the component. Auto-named if possible.

• options (dict) – User options that will override the defaults. Defaults to None.

• make (bool) – True if the make function should be called at the end of the init. Options be used in the make function to create the geometry. Defaults to True.

• component_template (dict) – User can overwrite the template options for the component that will be stored in the design, in design.template, and used every time a new component is instantiated. Defaults to None.

Raises:

ValueError – User supplied design isn’t a QDesign

Note: Information copied from QDesign class.

self._design.overwrite_enabled (bool): When True - If the string name, used for component, already exists in the design, the existing component will be deleted from design, and new component will be generated with the same name and newly generated component_id, and then added to design.

When False - If the string name, used for component, already exists in the design, the existing component will be kept in the design, and current component will not be generated, nor will be added to the design. The variable design.self.status will still be NotBuilt, as opposed to Initialization Successful.

Either True or False - If string name, used for component, is NOT being used in the design, a component will be generated and added to design using the name.
