StraightDirectionalCoupler
(*args, **kwargs)¶ A directional coupler consisting of 2 parallel (horizontal) straight waveguides.
Parameters: trace_template1: PCell and _WaveguideTemplate, optional
waveguide template used by the south arm of the directional coupler
trace_template2: PCell and _WaveguideTemplate, optional
waveguide template used by the north arm of the directional coupler. If not set, it defaults to the template of the south arm
wg1a: PCell, optional
South-west waveguide
wg1b: PCell, optional
South-east waveguide
wg2a: PCell, optional
North-west waveguide
wg2b: PCell, optional
North-east waveguide
coupler_length: float and Real, number and number >= 0, optional
length of the directional coupler
cell_instances: _PCellInstanceDict, optional
name: optional
The unique name of the pcell
n_inputs: int and number > 0, locked
Number of input channels.
n_outputs: int and number > 0, locked
Number of output channels.
