چکیده مقاله :
In this paper, a 2×1 Micro-Opto-Electro-Mechanical-Systems (MOEMS) multiplexer consisting of Metal-Insulator-Metal (MIM) waveguides and micro resonators is designed and numerically investigated. The proposed device takes the advantage of Surface Plasmon Polaritons (SPPs) propagation in the MIM structure and a mechanically tunable optical switch to realize the multiplexing function. According to the simulation results, the transmittances of the output channels of the device reach up to 72% at the desired wavelengths. Thereafter, the geometry of the proposed structure has been optimized to improve its functional characteristics. An extinction ration around 25.6 dB is obtained for the optimized two-channel structure in the operating wavelength range. Simple fabrication process, high efficiency, and low-cost manufacturing process make the proposed micro device a suitable choice for several applications in the area of optical telecommunications, especially wavelength division multiplexing. The proposed structure is composed of two main parts: a MEMS-based adder and a plasmonic switch.
