Abstract
An optical field concentrator includes a plurality of waveguide layers comprising high index materials having a first defined thickness. At least one nano-layer structure is positioned between said waveguide layers. The at least one nano-layer structure comprises low index materials having a second defined thickness that is smaller than the first defined thickness. A plurality of cladding layers are positioned between the waveguide layers and the at least one nano-layer structure. The cladding layers have a third defined thickness that is larger than the first defined thickness.
