摘要：
In this paper, we provide a comprehensive investigation for modes optical characteristics versus layers' thicknesses in straight hybrid plasmonic waveguides. Furthermore, we demonstrate how to exploit these characteristics to introduce a new simple scheme for sensing variations in surrounding refractive index by measuring phase difference between the TM and TE modes. The results show sensing sensitivity of 280 degrees per refractive index unit (RIU) for a gas refractive index sensor, with a very compact device length of 5 mu m.
