In a particular embodiment, a recording head includes a tapered waveguide adapted to propagate light from a light source a slider adjacent to a surface of a storage medium. The tapered waveguide is adapted to output an elliptical beam to a grating coupler on a slider. The recording head further includes a slider waveguide extending substantially normal to a surface of the storage medium and a grating adapted to couple the elliptical beam into the slider waveguide.
