Abstract
The present invention provides a method and apparatus for transforming optical wave modes. The apparatus includes a substrate and a first layer of waveguiding material above the substrate, the first layer having a first index of refraction, a first horizontal dimension, and a first vertical dimension. The apparatus also includes a second layer of waveguiding material adjacent the first layer, the second layer having a second index of refraction, a second horizontal dimension, and a second vertical dimension.
