Low Cost Optical Modeling Software by Junonia Photonics
Program MOL
Program MOL is a general purpose waveguide mode solver, which calculates the mode indices and fields for strip, rib, and other waveguide designs using the method of lines. Input and output is via text on screen, files on disk, and presentation quality graphics. Materials are characterized by their scalar refractive index. The method of lines algorithm is described in more detail in Fundamental Optical Models which can be purchased at Amazon, Barnes & Noble, or Routledge.
Examples:*
Electric field profiles for the HE00 and EH00 modes of a simple rectangular waveguide.
Convergence to an accurate mode index is rapid in the MOL technique.
Convergence of mode index as the line spacing is reduced and number of lines increased, and electric field contour plot for one layer thickness example.
Dispersion of mode indices for a square waveguide exhibiting avoided crossings making use of the bilateral symmetry.
Ex field profile for the HE00 mode of a half cylinder waveguide with bilateral symmetry using 50 lines and 12 layers.
*Note: all plots are generated using commercial graphics software from the text data output of the program though presentation quality graphics on the screen are also generated by the program.
