Abstract
An apparatus has a near-field transducer located proximate a media-facing surface of a slider magnetic recording heat. A waveguide is configured to couple light to the near-field transducer and includes a top cladding layer facing the near-field transducer, a bottom cladding layer, and a core layer between the top and bottom cladding layers. The apparatus includes a write pole with a flat portion substantially parallel to the core layer and a sloped portion extending from the flat portion of the write pole towards the media-facing surface at an angle to the core layer and to the media-facing surface. A light mitigation layer is located between the top cladding layer and the write pole.
