The Input Wave signal is defined within the Input Plane. To insert the Input Plane and
set the excitation wave, follow the steps below:
| Step | Action |
| 1 | From the Draw menu, select Vertical Input Plane, or select Vertical Input Plane shortcut toolbar (The Vertical Input Plane is in the x-y plane for 3D.) |
| 2 | Click in the layout window at the position where you want to insert the Input Plane. A red line that represents the input plane appears in the layout window. |
| 3 | To set up the Input Plane properties, double-click the red line (Input Plane) in the layout window. The Input Field Properties dialog box appears. |
| 4 | Set the time domain Input Plane basic information.
•    Select Gaussian Modulated Continuous Wave. The Gaussian Modulated CW tab appears. •    Wavelength (um): 1.55 Note: •    Continuous Wave The specified wavelength is a single wavelength that is used in simulations. •    Gaussian Modulated Continuous Wave The specified wavelength is the carrier wavelength (center wavelength) for the pulse simulations. |
| 5 | Click the Gaussian Modulated CW tab. To set the time domain input waveform. The time domain pulse graphics appear. Type the following values for the time domain input plane:
Time offset (sec.):                            1.5e-14 Half width (sec.):                              0.4e-14 Note: •    Both the time domain wave and frequency domain wave for the Input Plane appear. •    The Frequency domain information is obtained by FFT from the time domain series. •    Right Click on the graph and select the Zoom In tool to enlarge the selected graph region. You can observe the bandwidth in this way. •    Adjust half width can adjust the bandwidth |
| 6 | To set up the general information (transverse field distribution) for the Input Plane, click the General tab
•    Input Field Transverse: Rectangular •    Click 3D transverse to set the rectangular wave properties as the following: Center Position X:                     0.0 Half width X                               3.0 Center Position Y:                      2.5 Half width Y                               3.0 Tilting Angle:                              0.0 Effective refractive Index:          Local Polarization:                               Linear Y Amplitude:                                  1.0 |
| 7 | Click General tab. Set z-position in the Geometry and Wave Configure region as 1.0 |
