Abstract

A novel plasmonic unidirectional coupler and its extension to a multiplexer/demultiplexer are proposed and simulated. The proposed structure can be etched adjacent to metal-insulator-metal (MIM) waveguides which can result in considerable reduction in footprint of optical signal processing systems. Simulated results show very good agreement with design. Extinc�tion ratio (ER) of more than 11 dB was achieved for both the coupler as well as the multiplexer/demultiplexer. Crosstalk as well as full width at half maximum (FWHM) was also highly acceptable for the multiplexer/demultiplexer. The proposed structures have an additional attractive feature of being amenable to integration with other relevant functionalities as dem�onstrated in the results
