Here, we present parametric studies of a method for enhancing radiation from a dielectric waveguide through the use of resonant coreshells. These coreshells act as a compact impedance matching element between the guided modes of the waveguide and radiation modes in free space. Furthermore, we also show that we can sense the distance between the waveguide end and the coreshell by monitoring the reflectance of the waveguide mode. Coreshell decoupled radiation from dielectric waveguides could hence find use for highly integrated optical coupling elements or nanometric distance sensors.
