Input Wave

Compatibility:

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
