Outline of Final Research Achievements

In this study, we investigated the performance of integrated biosensors and gas detectors based on metal-assisted slot waveguides with high sensitivity. Numerical results show that the sensitivity of the metal-assisted slot waveguide is more than two times as large as the sensitivity of the conventional slot waveguide. In addition to this, we clarify that the mode coupling that deteriorates the sensitivity occurs between the TE mode and the TM mode at specific structures. Our research findings suggest that the use of the TE mode in certain plasmonic waveguides would be useful for some applications.
