RingShape

class picazzo3.filters.ring.cell.RingShape

Ring Resonator made of a single trace along an arbitrary shape.

The user supplies a Trace Template, as well as a shape to the Layout, from which the ring resonator waveguides are drawn.

By default, this ring has no couplers. you can supply the couplers manually as a list of child cells through the property ‘couplers’, or you can subclass this PCell to define the couplers internally.

Parameters:

ring_trace_template: PCell and _WaveguideTemplate

Trace template for the ring waveguide

ring_segments: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>

list of Ring PCells

couplers: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>

list of coupler PCells

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

The unique name of the pcell

Other Parameters:

ring_trace_templates: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, locked

Trace templates for the ring segments. Locked, as there is only one segment in this Ring. Use ‘ring_trace_template’ instead.

class Layout

Parameters:

shape_position: Coord2

Translation of the shape.

shape: Shape

Shape of the ring

coupler_transformations:

list of coupler transformations

area_layer_on: ( bool, bool_ or int )

When True, the Ring area will be covered by i3.Rectangles on all cover layers of the ring waveguide template.

coupler_parameters:

Parameters for the couplers. This is a list of dicts, and the length of the list should be the same as the number of couplers

view_name: String that contains only alphanumeric characters from the ASCII set or contains _$. ASCII set is extended on PY3.

The name of the view

Other Parameters:

shapes: locked

Shapes of the ring segments. Locked, as there is only 1 ring segment. Use ‘shape’ instead
