Abstract: A write head includes a near-field transducer near a media-facing surface of the write head. The write head includes a waveguide having a core with a first side disposed proximate to the near-field transducer. The core overlaps the near-field transducer at a substrate-parallel plane. The core includes one of a step or a taper on a second side facing away from the first side. The step or the taper causes a reduced thickness of the core normal to the substrate-parallel plane. The write head includes a cladding layer that encompassing the second side of the core and that fills in the step or the taper.
Abstract translation: 写头包括靠近写入头的面向媒体的表面附近的近场换能器。 写头包括具有芯的波导，第一侧靠近近场换能器设置。 核心在基板平行平面处与近场换能器重叠。 芯部包括在远离第一侧的第二侧上的台阶或锥形中的一个。 台阶或锥形导致芯垂直于基板平行平面的芯的厚度减小。 写头包括包围芯的第二侧并且填充在台阶或锥形中的包覆层。

Abstract: A planar collimator has first and second sections each intersecting at a junction between a first axis and a second axis normal to the first axis. Each of the first and second sections have geometries configured to receive light from a source point located on the first axis and collimate the light at respective positive and negative tilting angles relative to the second axis. The first and second sections direct the collimated light to respective first and second sides of a focusing mirror and away from a gap between the first and second sides of the focusing mirror.
Abstract translation: 平面准直器具有第一和第二部分，每个部分在与第一轴线垂直的第一轴线和第二轴线之间的接合处相交。 第一和第二部分中的每一个具有被配置为接收来自位于第一轴线上的源点的光的几何形状，并以相对于第二轴线的相应的正和负倾斜角准直光。 第一和第二部分将准直光引导到聚焦反射镜的相应的第一和第二侧并远离聚焦镜的第一和第二侧之间的间隙。
