“…Therefore, the use of surface plasmon polaritons (SPPs), which can be converted from optical energy and have no diffraction limit, is being considered for communication. However, SPPs have very high loss, making it difficult to construct devices or integrated circuits using only SPPs 5 , 6 . To address these issues, devices applying hybrid plasmonic structures that combine light and SPPs to effectively utilize the features of each to reduce losses have been reported 7 – 17 .…”

We fabricated a hybrid plasmonic device using self-imaging effect between guided light and surface plasmon polaritons in the hybrid plasmonic waveguide. The hybrid plasmonic device was fabricated by evaporating gold on the part of the silicon waveguide. Self-imaging was generated at the gold-covered section in the waveguide. Self-imaging of guided light and surface plasmon polaritons in hybrid plasmonic waveguides affect the output intensity of the hybrid plasmonic waveguide. The length of the hybrid plasmonic waveguide changes self-imaging conditions. We confirmed that the output intensity was affected by the length of the hybrid plasmonic waveguide. These findings contribute to the development of hybrid plasmonic devices and potentially improve integration density of hybrid photonic integrated circuits.
