WAVEGUIDE WITH TAPERED ASSISTANT LAYER |
| 摘要 |
An apparatus includes a waveguide extending along a light-propagation direction between a light source and a media-facing surface. An assistant layer is configured to receive light from a light source, the assistant layer has a terminating end with a first taper that narrows toward the media-facing surface. A core layer has a coupling end configured to receive light from the assistant layer, the coupling end having a second taper that widens toward the media-facing surface. A middle cladding layer is disposed between the core layer and the assistant layer. A near field transducer is disposed proximate the media-facing surface and configured to receive the light from the core layer. |

1. An apparatus, comprising:
a waveguide extending along a light-propagation direction between a light source and a media-facing surface, the waveguide comprising:
an assistant layer configured to receive light from a light source, the assistant layer comprising a terminating end with a first taper that narrows toward the media-facing surface;a core layer comprising a coupling end configured to receive light from the assistant layer, the coupling end comprising a second taper that widens toward the media-facing surface; anda middle cladding layer disposed between the core layer and the assistant layer; and a near field transducer disposed proximate the media-facing surface and configured to receive the light from the core layer. |
