    摘要： An apparatus includes a first waveguide configured to focus an electromagnetic wave to a focal region, and a second waveguide to further condense the light to an optical spot. The second waveguide includes a metallic structure defining an opening having one end positioned adjacent to the focal region and a multilayer structure positioned in the opening, the multilayer structure including a first layer of dielectric material, and second and third layers of dielectric material positioned on opposite sides of the first layer. A layer of lower index of refraction than that of the first dielectric layer may be positioned adjacent to the inner walls of the opening in the second waveguide to efficiently excite surface plasmons, and propagate them with low loss.

    摘要： A subwavelength aperture includes a plurality of ridges that project from an aperture sidewall into the aperture opening. The ridges may be closely spaced such that the hot spots associated with the ridges are likewise closely spaced and create an elongated hot spot. The subwavelength aperture of the present invention may be adapted for use in a magnetic head of a hard disk drive for improved thermally assisted recording (TAR) of magnetic data bits. Such a magnetic head may include an optical resonant cavity that is fabricated within the magnetic head structure.

    摘要： A magnetic recording head comprises a write pole tip adjacent to an air bearing surface and a return pole. In addition, a near field transducer is positioned adjacent the write pole in order to produce near field radiation to heat a portion of a recording medium to facilitate switching by the magnetic write pole. The near field transducer is a reverse optical near field transducer with internal bevel structures that enhance the magnetic write field intensity.

    摘要： A magnetic recording head consists of a write pole and a near field transducer close to the write pole that focuses light energy to a focal point. A near field transducer is positioned to receive light energy from a waveguide. The near field transducer comprises an energy-receiving end and an energy-radiating end. The energy-receiving end is located near the focal point of the waveguide and the energy-radiating end is shaped such that it is narrower closer to the write pole and wider farther from the write pole.
