To assign paths to the waveguides, perform the following procedure.
|1||From the Edit menu, select Edit Mode > Monitor Paths.|
The Path Monitor dialog box appears (see Figure 3).

|3||In the layout window, click the first waveguide.|
The defined path turns red (see Figure 5).

|4||To apply the path, click Finish.|
Path 1 appears in the drop-down list (see Figure 6).
Figure 6: Creating Path1
|5||Repeat steps 2 to 4 to assign a path to the second waveguide (see Figure 7).|
Path 2 appears in the drop-down list.

|6||To return to the layout window, click OK.|
The waveguides change back to the original color in the layout window.
|7||In the Layout Window, go to Simulation >> Path Monitor Type… and select Power overlap integral with fundamental mode with Global Normalization.|
