Abstract :
In this paper, we present a numerical study of a mode adapter that transitions light from a wide SOI waveguide to a narrower one. The device has been designed using the technique of transformation optics and consists of a thin sheet of anisotropic medium directly placed on top of the Si slab. We demonstrate that this sheet effectively controls the flow of energy propagating in the Si slab and that the structure can be potentially implemented by patterning a single layer of planar optical metamaterial on the SOI waveguide.
