Hybrid Wedge-integrated Plasmonic-photonic Waveguide

Abstract

In this work, a novel design of hybrid integrated plasmonic-photonic waveguide is proposed to work at 1550 nm wavelength and have low loss specification of photonic waveguides and high optical mode confinement of plasmonic waveguides. Unlike other designs, metallic nanoparticles are deposed inside the mask layer to have less radiation from the waveguide and increase transmitting light. Moreover, by using wedge shape for the mask layer of the waveguide, higher order modes suppress.
