✦ Synopsis
Pre¨ious designs for wa¨eguide mode con¨erters generally assume a pure input mode at the input. Howe¨er, in the actual case, the main input mode is usually accompanied by se¨eral spurious modes with small fractional power le¨els. Based on the coupled-mode theory, this letter presents a study on the influence of an input mode mixture in wa¨eguide mode con¨erters with ¨arying wa¨eguide radii. A new wa¨eguide radius perturbation form for transforming such a spurious input mode mixture simultaneously into the main output mode is also proposed in this letter.
