Higher Order Mode


If the current fiber design supports multiple modes their characteristics can be
calculated the following way:

Step Action
1 In the “Modes” dialog box recalculate and select the higher-order mode of interest. In that example of a typical 65/125 multi-mode graded-index fiber it is LP(3,6)

Optical Fiber - Modes”Click the “High Order Mode” icon in the Navigator pane. The “Properties of High Order
Mode” dialog box appears.

Optical Fiber - High Order ModeIt offers the choices to calculate (scan) the characteristics of the selected mode vs.
the wavelength, the proportionally reduced/expanded profile width, etc. After the
calculation the results are displayed in the same view tabs described above.
