| Summary: | 碩士 === 國立高雄應用科技大學 === 電子工程系 === 105 === In this thesis, we discussed the characteristics of the surface plasma waveguide elements and investigated the proposed metal-insulator-metal (MIM) plasmonic waveguide structures with the nano- ring resonators to design all-optical devices. First of all, we first proposed a MIM plasmonic refractive index sensor which composed of a ring resonator and two bus waveguide and analyze of the parameters of the proposed all-optical temperature sensor. Its sensitivity reached 3670 (nm/RIU), the figure of merit reached 917(RIU-1), and the highest transmission efficiency reached 99.8%. Then we use the characteristics of ring waveguide resonance, and analyze the parameters of the ring resonant waveguide for the transmission spectrum resonance wavelength and bandwidth. Based on this, and fill in the nonlinear material, change the input electric field strength, design all-optical filter and logic gates. For the proposed AND logic gate, the normalized transmission of the high logic state is about 97.5% and the low logic state is 0.2%. For the proposed OR logic gate, the normalized transmission of the high logic state is about 97.5% and the low logic state is 0.2%. For the proposed NOR logic gate, the normalized transmission of the high logic state is about 95.4% and the low logic state is 0.01%. For the proposed XNOR logic gate, the normalized transmission of the high logic state is about 98.2% and the low logic state is 0.01%. For the proposed NAND logic gate, the normalized transmission of the high logic state is about 94.3% and the low logic state is 0.015%. For the proposed XOR logic gate, the normalized transmission of the high logic state is about 97.6% and the low logic state is 0.1%. In the future, the proposed all-optical devices based on MIM plasmonic waveguide structures with the nano-ring resonators could be applied to optical signal processing and communication systems.
