A Mach-Zehnder arm with a given length: routing upward at right-angle
trace_template: PCell and _WaveguideTemplate
Dictionary for remapping of the port names of the contents to the external ports
The unique name of the pcell
contents: PCell and _Trace, locked
angle_step: float and number > 0
Angle step for rounding.
Port interface of the combiner to which the output of this arm is connected
layer on which the control shape is drawn
cover_layers: List with type restriction, allowed types: <class ‘ipkiss.primitives.layer.Layer’>
layers that can be used to generate additional coverage of the trace (e.g. manhattan corners)
draw_control_shape: ( bool, bool_, bool or int )
draws the control shape on top of the waveguide
extra_length: float and Real, number and number >= 0
Extra length that will be added in the arm
manhattan: ( bool, bool_, bool or int )
Adds rectangular blocks in the bends to avoid as much as possible non-manhattan angles.
Port interface of the splitter to which the input of this arm is connected
view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
min_straight: float and Real, number and number >= 0
Minimum straight length between bends
direction of routing (DIRECTION.NORTH or DIRECTION.SOUTH)
flatten_contents: ( bool, bool_, bool or int )
if True, it will insert the contents as elements in the layout, rather than as an Instance
layer used to define the core of the waveguide
bend_radii: list<number > 0>
Bend radius for every individual bend.
remove_straight_angles: ( bool, bool_, bool or int )
Removes the waypoints with straight angles. Set to False if the algorithm uses waypoint-specific information.
reverse_bends: ( bool, bool_, bool or int )
When set to True, it will generate the bends backwards. This has only effect when the bend algorithm is not symmetric.
reverse_individual_bends: list<( bool, bool_, bool or int )>
When set to True, it will generate the individual bends backwards. This has only effect when the bend algorithm is not symmetric. Should have length equal to the shape for closed shapes, but equal to shape-2 for open shapes.
Rounding algorithm for every individual bend. Can be circular, spline, … Should have length equal to the shape for closed shapes, but equal to shape-2 for open shapes.
Trace template to be used for the ports.
bend_radius: float and number > 0
Bend radius for the auto-generated bends.
Rounding algorithm used to generate the bends. Can be circular, spline, ….
Automatically calculated shape of the center line of the trace
