Abstract

The modal behavior of rib antiresonant reflecting optical waveguides (ARROWs) is theoretically analyzed in this work. Two numerical analysis methods have been used for the analysis of an open rib structure: the spectral index method and a vectorial mode matching method, where the real and the imaginary part of the modal solutions of several structures have been studied. A nearly polarization independent open rib structure and a embedded rib structure have also been studied using the mode matching method. Obtained numerical results will be also compared with experimental data in order to point some observed discrepancies
