1. An apparatus, comprising:
an input region comprising an input surface configured to receive energy emitted from an energy source in a first mode; a mode order converter configured to convert the energy from the first mode to a second mode; a waveguide comprising top and bottom cladding layers and a core disposed on a substrate-parallel plane therebetween, an input end disposed proximate the input surface and configured to receive the energy in the first mode, and an output end disposed proximate a media-facing surface and configured to deliver energy in the second mode, the output end being at a first oblique angle to a cross-track line at an intersection of the media-facing surface and the substrate-parallel plane; and a near-field transducer located proximate the core and proximate the media-facing surface. |
