Abstract:
      Different characteristics of fundamental mode of hybrid dielectric loaded plasmonic waveguide have been explored at 1 550 nm wavelength, to resolve the issue of large propagation loss and diffraction limit with minimal waveguide dimension.Propagation length of 432 ?m has been achieved with the optimal dimension of 200 nm×40 nm. Through the numerical simulation results, the effective area of 0.021μm2 and normalized intensity of 40.71 μm-2in the spacer region of the waveguide have been realized. To accomplish the ultra-compact directional coupler, the smaller coupling length of about 1.42 ?m has been achieved. PTFE-based waveguide can be highly beneficial for the realization of monolithic integration with active optical devices.
