Abstract

A multimode interference half-power splitter on hollow core polysterene-coated metallic waveguide is demonstrated in this study. The modal properties, propagation length, optical field evolution, and dispersion of the aforementioned device have been investigated using the full vectorial finite-element-based modal analysis and beam propagation method, as well as the finite-difference time-domain approach.
