WgDirectCrossing

class picazzo3.wg.crossing.cell.WgDirectCrossing

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:

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

the waveguides through the crossing

trace_template: PCell and _WaveguideTemplate

Trace template used to define the crossing

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

The unique name of the pcell

Views

class Layout

Parameters:

straight_stub: float and number > 0

length of the straight sections of the crossing

length: float and number > 0

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
