Abstract
Apparatus including: a substrate layer having a substantially planar top surface; an optically conductive peak located and elongated on, and spanning a first thickness measured in a direction generally away from, the top surface; the optically conductive peak having first and second lateral walls each including distal and proximal lateral wall portions, the proximal lateral wall portions intersecting the top surface; and first and second sidewall layers located on the distal lateral wall portions, the sidewall layers not intersecting the top surface and spanning a second thickness that is less than the first thickness measured in the same direction.
