Abstract: We analyzed output Surface Plasmon-Polariton (SPP) modes with gold structures in a gap when polarized light propagated across Gapped SPP Waveguides (G-SPPWs). The G-SPPWs consist of input and output insulator-metal-insulator typed SPPWs with a gap. The dielectric channel waveguide is laid across the gap. Gold was used as the metal of the SPPWs. Low loss polymers were used as the upper and lower cladding layers and the core of the dielectric channel waveguide, respectively. The input SPP mode intersects at the gap with the polarized light launched to the dielectric channel waveguide. When the TE polarized light is applied, lossy short-range SPP (SRSPP) modes are overlapped in the output SPPW. For the TM polarized light, the output SPP mode has low loss though there are mode fluctuations. When horizontal and vertical gold strips are placed in the gap and the TE polarized light is applied, the propagation loss increases significantly depending on the shape of the gold strips due to TE-i nduced symmetric surface charges. Inverted plasmonic signals can be generated from optical signals by the SPP modulation using excited SRSPP modes. The modulation efficiency can be increased by introducing photonic crystal or plasmonic resonance in the gap. (More)
