An apparatus for energy assisted magnetic recording of a storage disk includes a plurality of dielectric waveguide cores disposed near an air bearing surface of a magnetic recording device. Each waveguide core has a fine ridge feature on a first surface of the waveguide core and configured to receive incident light energy from an energy source. A near field transducer (NFT) is formed at the air bearing surface for focusing light energy received from the waveguide core and transmitting the focused light energy onto the storage disk surface to generate a heating spot. The NFT includes at least one plasmonic metal element disposed above the fine ridge features of the waveguide cores to form an interface for delivering propagating surface plasmon polaritons (PSPPs) to the air bearing surface. Each fine ridge feature is configured with a width approximately equivalent to a width of the heating spot.
