摘要： A structure includes a channel waveguide and a pocket adjacent to an input facet of the channel waveguide. A laser having an output facet is positioned in the pocket. The structure includes a stop on either the laser or a wall of the pocket. The stop is positioned at an interface between the laser and the wall of the pocket such that the output facet of the laser and the input facet of the waveguide are separated by a gap.

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： Methods for forming a SiC BJT having a low base resistance and minimal emitter width are provided. The methods incorporate a plated shadow metal layer overhanging the emitter mesa. The mushroom-shaped shadow metal layer can then act as either a deposition shadow mask or an ion implantation mask in subsequent steps for forming base contacts. In this way, base contacts can be formed with a variable and controllable distance from the emitter mesa defined by the lateral extent of overhang of the shadow metal layer. The same shadow masking effect can also be used to form self-aligned emitter and base wiring metals for reduction of resistance. Plating of the emitter contact layer allows avoiding subsequent photolithography steps on the top of emitter mesa; thus emitter mesa width could be minimized.

摘要： A magnetic recording head comprises a write pole having a pole tip adjacent to an air bearing surface, a return pole, an optical near field transducer positioned adjacent the pole tip and an air bearing surface for exposing a portion of a magnetic storage medium to high energy radiation. The energy is directly provided to the near field transducer by a ridge waveguide with tapered coupling elements, by a two dimensional straight or curved waveguide with a beveled end with a metal/dielectric coating for delivering energy to the near field transducer, or by a curved waveguide. The waveguide with tapered coupling elements or with beveled end can be fabricated by means of conventional wafer processing.
