英文摘要	A recording head has a primary waveguide core with an input end at an input surface of the recording head and extends to a near-field transducer at a media-facing surface of the recording head. A secondary waveguide core is separated from the primary waveguide core by a gap such that light is evanescently coupled from the primary waveguide core to the secondary waveguide core. The secondary waveguide core has first and second bends such that an output end of the secondary waveguide core is parallel to and separated from the primary waveguide core in a cross-track direction. A polarization rotator rotates a polarization of light in the secondary waveguide core such that polarization-rotated light exits the secondary waveguide core at the media-facing surface.
