S-Bend Routing

This example demonstrates how to use i3.ConnectSBend to route between two optical ports that are slightly offset but facing each other.

import ipkiss3.all as i3

wg = i3.Waveguide()

circuit = i3.Circuit(
    specs=[
        i3.Inst(["wg1", "wg2"], wg),
        i3.Place("wg1", (0.0, 0.0)),
        i3.Place("wg2", (50.0, 20.0)),
        i3.ConnectSBend(
            "wg1:out", "wg2:in", sbend_type=i3.SBendType.Sine, min_bend_radius=10.0, connection_name="my_sbend"
        ),
    ],
)

Visualizing the layout

layout = circuit.Layout()
fig = layout.visualize(annotate=True, show=False)
fig.savefig("plot_connect_sbend.png")
