DoubleSpiralWithInCoupling
(*args, **kwargs)¶ Double spiral class with both access waveguides on the outside of the spiral. In coupling waveguides are added to the spiral, one at the east side and one at the west side. The trace template provided in the property
trace_template
is used to build a chain of waveguides.Parameters: n_o_loops: int and number > 0
Number of loops in the spiral
trace_template: PCell and _TraceTemplate
Trace template used in the chain.
name:
The unique name of the pcell
Other Parameters: traces: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, locked
n_o_traces: int and number > 0, locked
Total number of traces used in the spiral.

Layout
¶ Parameters: shapes: list
List of shapes used to build the traces
stub_direction:
view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
incoupling_length: float and Real, number and number >= 0
length of the incoupling section.
inner_size: Coord2
Inner size of the the spiral, defaults to 3 * spacing + 2 * bend_radius, in each direction
spacing: float and Real, number and number >= 0
spacing between the individual loops.
flatten: ( bool, bool_, bool or int )
If true the instances are flattened
Other Parameters: spiral_center: locked
auto_transform: locked
