    Abstract: A collimator array, a fiber array and a method for fabricating the fiber array are described herein. In one embodiment, that fiber array includes a plurality of optical fibers and a glass plate with a plurality of holes in each of which there is secured one of the optical fibers, wherein the holes were formed by etching away a plurality of opal regions within an exposed and heated photosensitive glass which after the etching became the glass plate. In another embodiment, the fiber array includes a plurality of optical fibers and a glass plate with a plurality of holes in each of which there is secured one of the optical fibers, wherein the holes were formed by etching away a plurality of opal regions within an exposed and heated photosensitive glass which after the etching became the glass plate that included a plurality of oversized holes which were filled with a moldable material that was then drilled to form the holes.

    Abstract: A lens array and a method for fabricating a lens array that is relatively flat and has useful lenses with relatively uniform sag heights are described herein. In one embodiment, the lens array includes a one-dimensional array of useful lenses and two sacrificial lenses each of which is formed next to an end of a row of the useful lenses to help maintain relatively uniform sag heights across the useful lenses. In another embodiment, the lens array includes a two-dimensional array of useful lenses and a plurality of perimeter lenses each of which is formed next to an end of a row or a column of the useful lenses to help maintain relatively uniform sag heights across the useful lenses. In yet another embodiment, the lens array includes an array of useful lenses and a glass region (including possibly a glass matrix) located within an opal border and outside an opal region that surrounds the useful lenses to help minimize warpage of the lens array. In fact, there are many different embodiments of the lens array described herein that incorporate one or more of the aforementioned features.
