Claim Text:
1. A near-field transducer comprising: an enlarged region having a top side adjacent to a magnetic pole, a base side opposite the top side, and a circumference that extends from proximal to a media-facing surface to distal from the media-facing surface; a peg region in contact with at least a region of the base side of the enlarged region and extending from the enlarged region towards the media-facing surface; and a heat sink region having a contact side and a base side, and a circumference that extends from proximal to the media-facing to distal from the medial-facing surface, wherein the contact side of the heat sink region is in physical contact with both the peg region and at least a region of the base side of the enlarged region, and the heat sink is formed from plasmonic material and configured to enhance coupling efficiency of the near-field transducer.
