Abstract
A device includes a body, a waveguide, and a near field transducer (NFT). The body has opposed first and second surfaces. The waveguide is adapted to receive light and convey the light to a distal end of the waveguide. The NFT is disposed proximate the distal end, and it has an output end proximate the first surface of the body. The device further includes a surface-emitting distributed feedback (SE-DFB) laser that is mounted on and attached to the body and positioned to inject laser light into the waveguide. The device may be a recording head, and the laser, the waveguide, and the NFT may cooperate to provide electromagnetic heating to a substrate for heat assisted magnetic recording.
