Abstract
A light delivery system in a slider includes a channel waveguide, a mode-index refractive surface, a solid immersion mirror, and a near field transducer. The mode-index refractive surface shapes the angular spectrum of the light on its path to the solid immersion mirror in a manner so as to change the distribution of light energy focused on to the near field transducer.
