| 英文摘要 | A slider includes a slot waveguide configured to receive energy from an input surface. The slot waveguide has first and second high-index regions surrounding a middle region that extends along a light propagation direction. The middle region has a refractive index less than that of the first and second high index regions. A near-field transducer is at an output portion of the middle region at media-facing surface. The near-field transducer has first and second plates parallel to the media-facing surface with a gap therebetween. An active laser region has a front facet optically coupled to the input surface of the slider. A reflective back facet of the laser and the near-field transducer define a single optical resonator. |
