    摘要: An apparatus for producing a small spot of optical energy comprises a planar waveguide shaped to direct a linearly polarized electromagnetic wave to a focal point within the waveguide, and a metallic pin positioned at the focal point whereby the linearly polarized electromagnetic wave creates surface plasmons on a surface of the pin. The apparatus can further comprise means for phase shifting a portion of the linearly polarized electromagnetic wave. Recording heads comprising a magnetic write pole, a planar waveguide positioned adjacent to the magnetic write pole, the planar waveguide being shaped to direct a linearly polarized electromagnetic wave to a focal point within the waveguide, and a metallic pin positioned at the focal point whereby the linearly polarized electromagnetic wave creates surface plasmons on a surface of the pin, and disc drives that use such recording heads are also disclosed.

    摘要: 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.
