The Input Wave signal is defined within the Input Plane. To insert the Input Plane and
set the excitation wave, follow the steps below:
|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
• 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
• 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
|7||Click General tab. Set z-position in the Geometry and Wave Configure region as 1.0|
