    Abstract: A recording head has a near-field transducer proximate a media-facing surface of the recording head. The near-field transducer extends a first distance away from the media-facing surface. A waveguide overlaps and delivers light to the near-field transducer. Two subwavelength focusing mirrors are at an end of the waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface; and a second material facing away from the media facing surface and in contact with the first material. The second material includes a plasmonic material, and the first material is more mechanically robust than the second material.

    Abstract: A head assembly includes a submount, a body with a first surface, an optical path, a near field transducer (NFT), a sensor, and a laser. The optical path is disposed in the body and is adapted to receive light and convey the light to a distal end of the waveguide. The near field transducer (NFT) is disposed adjacent the distal end of the waveguide and has an output end proximate the first surface of the body. The sensor interfaces with the submount and the laser is attached to the submount along a non-primary lasing surface. The laser is adapted to inject light into the waveguide and includes a grating adapted to diffract a portion of the light through the non-primary lasing surface to the sensor.
