WgDirectCrossing

class picazzo3.wg.crossing.cell.WgDirectCrossing(*args, **kwargs)

A Direct waveguide crossing, consisting of two identical waveguides at right angles. This design is not particularly efficient for high-contrast waveguides, but is OK for low-contrast waveguides (e.g. silica.)

Parameters:

trace_template: PCell and _WaveguideTemplate, optional

Trace template used to define the crossing

waveguides: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, optional

the waveguides through the crossing

cell_instances: _PCellInstanceDict, optional

name: optional

The unique name of the pcell

Views

Layout

Parameters:

view_name: str, optional

The name of the view

length: float and number > 0, optional

straight_stub: float and number > 0, optional

length of the straigth sections of the crossing

grids_per_unit: locked

Number of grid cells per design unit

units_per_grid: locked

Ratio of grid cell and design unit

grid: float and number > 0, locked

design grid. Extracted by default from TECH.METRICS.GRID

unit: float and number > 0, locked

design unit. Extracted by default from TECH.METRICS.UNIT
