Standard-shaped directional coupler.
Described by a gap, length, horizontal and vertical distance.
- Parameters
width (float) – Width of waveguides in nanometers (valid from 400 to 600).
thickness (float) – Thickness of waveguides in nanometers (Valid from 180 to 240).
gap (float) – Distance between the two waveguide edges, in nanometers (must be greater than 100).
length (float) – Length of the straight portion of both waveguides, in nanometers.
horizontal (float) – Horizontal distance between end of coupler and straight segment, in nanometers.
vertical (float) – Vertical distance between end of coupler and straight segment, in nanometers.
sw_angle (float, optional) – Sidewall angle of waveguide from horizontal in degrees (valid from 80 to 90, defaults to 90).
