The modal analysis module is an integral part of the KloéSoftwave software suite.

It allows the design of a fibre or an optical circuit index profile, to integrate it in a more complex structure, to simulate defects.

The analysis itself employs an algorithm of calculation by finite elements. It provides effective indexes of guided and radiative modes.

The light distribution for each mode can be viewed in 2D or 3D in order to give a better idea of phase shift.
