The Input Wave signal is defined within the Input Plane. To insert the Input Plane and
set the excitation wave, follow the steps below:

StepAction
1From 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.)
2Click 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.
3To set up the Input Plane properties, double-click the red line (Input Plane) in the layout window. The Input Field Properties dialog box appears.
4Set 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.

5Click 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

6To 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

7Click General tab. Set z-position in the Geometry and Wave Configure region as 1.0
