1. A combination of optical elements, the combination comprising:

  • an optical component comprising;

    an input surface, an output surface opposite the input surface, a length extending between first and second ends, and a width transverse to and substantially smaller than the length and extending between first and second sides;

    a non-planar refractive portion disposed between the first and second sides and extending along the length between the first and second ends; and

    a plurality of separate reflective portions disposed on opposite sides of the non-planar refractive portion and extending along the length between the first and second ends;

    wherein the refractive portion and the plurality of separate reflective portions comprise at least a portion of the input surface of the optical component;

    wherein each reflective portion comprises a plurality of inner and outer surfaces;

    wherein each outer surface reflects light that is refracted into the optical component by each respective inner surface; and

    wherein the inner surfaces are parallel to one another and transverse to the output surface; and

    an optical waveguide comprising a second input surface adjacent and parallel to the output surface of the optical component.
