In this paper, an input coupler to efficiently couple light from a silicon slab waveguide to a silicon slot waveguide is proposed. The slab waveguide is tapered to slot waveguide dimension for minimum loss. It also allows a miniaturized and compact design. Typical parameter such as taper length is numerically optimized to obtain minimum insertion and return losses as compared to other existing couplers.
