| 英文摘要 | An apparatus includes a waveguide, a laser diode positioned adjacent to the waveguide and having an active region producing light in a plane substantially parallel to a plane of the waveguide, a first grating positioned to couple light out of the laser diode and to direct the light toward the waveguide, a reflective layer positioned adjacent to a side of the first grating opposite to the waveguide, and a second grating having the same period as the first grating and positioned to couple light into the waveguide. A data storage device that includes the apparatus is also provided. |
