WireRibWaveguideTransitionFromPortLinear

class picazzo3.traces.rib_wg.WireRibWaveguideTransitionFromPortLinear

Transition from/to wire (deep etched) to/from rib (shallow etched) waveguides.

You can provide a start_port and end_trace_template.

Parameters:

wire_only_wg_template: PCell and _TraceTemplate

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)

start_port: _PortInterface

the port on which to extract trace template, position and angle

end_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate, RibWaveguideTemplate

start_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate, RibWaveguideTemplate

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:

wire_only_length: ( float and Real, number and number >= 0 ), *None allowed*

Length of transition where shallow part is built up.

wire_only_cladding_width: float and number > 0

width of the cladding at the end of the wire_only_length

wire_end_width: float and Real, number and number >= 0

width of the wire core at its end point.

straight_extension: Coord2 and number >= 0

tuple: straight extension at start and end of transition

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

length of the 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

Examples

"""This example shows how to append a transition onto a component.
The component has a port, which is associated with a
WireWaveguideTemplate, and we want to taper to a RibWaveguideTemplate.
