class
picazzo3.traces.thin_wg.
ThinnedWaveguideTemplate
(*args, **kwargs)¶ Thinned waveguide.
Takes an existing waveguide template (given by trace_template) and overlay with a thinning layer.
Parameters: trace_template: PCell and _TraceTemplate
Refers to the other trace template from which information is taken to build this trace template.
name:
The unique name of the pcell

Layout
¶ Parameters: control_shape_layer: __Layer__
layer on which the control shape is drawn
keep_original_trace_template: ( bool, bool_, bool or int )
pin_shape: Shape
shape to be used for the pins
thin_process: ProcessLayer
thinning process
thin_purpose: PatternPurpose
drawing purpose for the thinning region
thin_width: float and Real, number and number >= 0
width of the thinning layer
trace_template_for_ports: _TraceTemplate.Layout
Trace template to be used for the ports. Default = this template
view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
windows: List with type restriction, allowed types: <class ‘ipkiss3.pcell.trace.window.window._TraceWindow’>
List of Trace Windows to draw on top of the already defined TraceTemplate
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)
cladding_process: ProcessLayer
process for the waveguide cladding, defaults to the core process
cladding_purpose: PatternPurpose
drawing purpose layer for the cladding
cladding_width: float and number > 0
total width of the waveguide with cladding
core_process: ProcessLayer
process for the waveguide core
core_purpose: PatternPurpose
drawing purpose for the waveguide core
core_layer: __Layer__
layer used to define the core of the waveguide
core_width: float and number > 0
width of the waveguide core
flatten_contents: ( bool, bool_, bool or int )
if True, it will insert the referred trace as elements in the layout, rather than as an Instance
draw_control_shape: ( bool, bool_, bool or int )
draws the control shape on top of the waveguide
Other Parameters: width: locked
