WireRibWireWaveguideTransitionLinear

class picazzo3.traces.rib_wg.WireRibWireWaveguideTransitionLinear

Transition from/to wire (deep etched) to/from ribwire (two-step etched) waveguides.

You can provide either a wire for the start, and ribwire for the end, or vice versa.

Parameters:

modified_start_wg_template: PCell and _TraceTemplate

Modified start waveguide template (using the end_trace_template, but with the dimensions of the start_trace_template)

end_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate, RibWireWaveguideTemplate

start_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate, RibWireWaveguideTemplate

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:

reverse_templates: ( bool, bool_ or int ), locked

When True, treat start_trace_template as end_trace_template and vice versa. To use the correct templates, use the _{start/stop}_trace_template properties. This should not be set manually, but calculated by the transition itself.

Views

class Layout

Parameters:

straight_extension: Coord2 and number >= 0

tuple: straight extension at start and end of transition

end_position: Coord2

end position of the transition

start_position: Coord2

start position of the transition

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:

length: float and Real, number and number >= 0, locked

length of the transition
