Examples

Example 1 - Rectangular Waveguide

Shows basic construction of a rectangular waveguide, solving and mode-plotting.

• Introduction to pyfimm syntax, written for users somewhat new to Python.
• Create a new Project, and a new RWG Rectangular Waveguide in that Project
• Solve for the modes & plot them
  • Highlights the mode-plotting features, such as plotting multiple-modes on a single plot figure.
  • Return Electric-Field values
• Shows ways to find more features & get help using standard Python techniques, such as
  • >>> help( pyfimm )
  • >>> dir( MyObject )
  • >>> help( MyWaveguideObj.calc )

Example 2 - FimmProp Device

• Concatenate two Waveguides together in a FimmProp Device.
• Uses a FimmWave Material Database.
• Annotating a Plot by returning the figure handles, using MatPlotLib (matlab-like plotting).
• Saving a Project to a file

Example 3 - Solve for modes of an Optical Cavity

• Based on the FimmProp Example: Modes of a VCSEL/DFB Cavity
• Cylindrical coordinate devices (eg. Fibers)
• Repeating Layers in Devices (using python's List multiplication syntax)
• Sweep wavelength to solve for the longitudinal modes of the cavity
• Plot the cavity fields and refractive index
• Sending raw commands to FimmWave

Example 4 - Loading Devices from a File

This allows you to use all the capabilities of the FimmProp GUI to generate your Devices (with curved paths, etch/grow regions etc.), and just import that into pyFIMM for doing your loops/analyses.

• Open a saved Project file
• Copy a Device from the Project file into our own Project, and interact with the new Device.
