Abstract

A modulation efficiency enhancement scheme for an InGaAsP waveguide-coupled micro-ring cavity resonator utilizing the self-aligned total internal reflector mirrors was proposed and investigated numerically and experimentally. Unlike the conventional electroabsorption modulators, the micro-ring cavity resonator was found to exhibit a singular modulation characteristics depending on the coupling coefficient between the micro-ring cavity and the input/output waveguide, which can be exploited to enhance the optical modulation efficiency as well as the extinction ratio.
