Lesson 2: Create a Simple MMI Coupler
Defining Materials for the MMI Coupler
To define the materials for the MMI coupler, perform the following procedure. Step Action 1 From the File menu, select New. The Initial Properties dialog box appears (see Figure 1). Figure 1: Initial Properties dialog box 2 Click Profiles And Materials. The Profile Designer window appears (see Figure 2). Note: To ensure that you can…
Defining the Layout Settings
To define the layout settings, perform the following procedure. Step Action 1 Click the Default Waveguide tab. 2 Type the following value: Width: 2.8 Note: All waveguides will use this setting as the default thickness. 3 In the Profile list, click channel. 4 Click the Wafer Dimensions tab. 5 Type the following values: Length: 5300…
Creating an MMI Coupler
To create an MMI coupler, perform the following procedure. Step Action 1 From the Draw menu, select Linear Waveguide. The cursor changes into a cross-hair. 2 To draw the first waveguide, in the layout window, click in the left side of the layout, drag the waveguide towards the right side of the layout window, and release…
Inserting the Input Plane
To insert the input plane, perform the following procedure. Step Action 1 From the Draw menu, select Input Plane. 2 To insert the input plane, click as close to the left side of the layout window as possible. The input plane appears (see Figure 14). Figure 14: Input plane 3 To edit the input plane,…
Running the Simulation
To run the simulation, perform the following procedure. Step Action 1 From the Simulation menu, select Calculate 2D Isotropic Simulation. The Simulation Parameters dialog box appears (see Figure 22). Figure 22: Simulation Parameters dialog box 2 To start the simulation, click Run. The OptiBPM_Simulator appears and the simulation starts. Note: The simulation in this lesson…
Viewing Results in the BPM Analyzer
To view the simulation results in OptiBPM_Analyzer, perform the following procedure. Step Action 1 To view and analyze the optical field view, in the directory in OptiBPM_Analyzer, double-click Optical Field Propagation. 2 Click XZ Slice. The optical field view of the simulation results appears (see Figure 30). Figure 30: OptiBPM_Analyzer — Optical Field Propagation 3 To…
