To modify the layout script, perform the following procedure.

1Click the Scripting tab.

The Scripting window appears.

2Type the following lines at the end of the layout script:

BPM - Script

Note: The first lines draw the layout, and the above lines enter a loop. The layout is adjusted to move the coupler waveguides farther apart in each iteration. Each loop ends with a ParamMgr.Simulate command which calls the simulator for the current layout.

3 Save the project.
4From the Simulation menu, select Calculate 2D Isotropic Simulation.

The Simulation Parameters dialog box appears (see Figure 26).

5Under Simulation technique, click Simulate Using Script.
6Click Run.

The simulator runs 10 times and the progress is reported in the Notification window (see Figure 27).
