Abstract
Systems and methods for suppressing the background energy of a waveguide in an EAMR system are provided. One such system includes a near field transducer having a disk section and a pin section extending from the disk section to an air bearing surface of a slider, a waveguide having a core and a cladding, where the waveguide is configured to couple light energy to the near field transducer, where the cladding is configured to substantially surround the core, and a recess portion positioned between the core and the air bearing surface.
