dc.description.abstract	A novel rectangular nano-plasmonic coupler based on Gallium Arsenide (GaAs) has been suggested that has an air slot inserted into the dielectric waveguide, considering air as the dielectric material of the metal-dielectric-metal (MDM) plasmonic waveguide. The finite integral technique (FIT) based simulation software which was a commercial software named CST Microwave Studio yielded a coupling efficiency of 81.07% at the wavelength of optical communication i.e. 1.55μm. The most efficient coupling structure has been attained by analyzing the performance with a variety of different dimensions which subsequently results in decent performance over a wide range of wavelengths above the visible spectrum. The elementary flat rectangular composition of the suggested coupler without any tapered edges provides convenience in the manufacturing process, making the coupler affordable and peerless.	en_US
