Mode Sensitivity Exploration of Silica–Titania Waveguide for Refractive Index Sensing Applications

Mode Sensitivity Exploration of Silica–Titania Waveguide for Refractive Index Sensing Applications

In this paper, a novel and cost-effective photonic platform based on silica–titania material is discussed. The silica–titania thin films were grown utilizing the sol–gel dip-coating method and characterized with the help of the prism-insertion technique. Afterwards, the mode sensitivity analysis of...
