A highly selective plasmonic demultiplexer based on a plasmonic slot waveguide platform is proposed. The structure is optimized as an add drop multiplexer/demultiplexer. The optimal design is targeting minimum FWHM. The device is optimal quad multiplexer/demultiplexer has FWHM of 9.8 nm for each channel with a high output transmission near the 1550 nm. The proposed structure is simple, can be easily fabricated. Extended optimization was performed that enabled the multiplexed signal to have FWHM of 8.16 nm with peak power of 30 % near the 1300 nm. The structure can be utilized for double channel multiplexing applications and more by doing the needed optimization for such high scalability.
