| 英文摘要 | An apparatus includes a waveguide including a core layer having curved edges shaped to reflect light to a focal point, and a grating positioned adjacent to or imbedded in the core layer, wherein at least a portion of the grating is positioned between the curved edges and adjacent to or imbedded in a portion of the core layer that is not traversed by light reflected from the curved edges. A data storage device that includes the apparatus is also provided. |
