Bicontrollable Optical and Plasmonic Waveguide

Abstract

In this work, we propose electrical and thermal control over a horizontal slot waveguide. The proposed device takes advantage of the thermally dependent transition phases of Vanadium Dioxide (VO2), and a high r33 electro-optic polymer called BAY1, which is responsible for the electrical control. We demonstrated a transitioning waveguide which can be used in different applications ranging from phase shifting to plasmonic waveguide feeding by engineering the effective index and mode distribution. Additionally, we report a band gap in our modal analysis that can be engineered without using periodical segmentation, rendering our discovery a useful bicontrollable metawaveguide.
