    摘要： A tapered waveguide improves insertion loss occurring at the slab/waveguide interface of an optical array waveguide grating (AWG). The tapered waveguide has two segments. The first segment decreases from a first thickness, nearest the slab of the AWG to a second thickness moving away from the slab. The second segment has a substantially constant or uniform thickness equal to the second thickness of the first segment. The second segment may also have a swallowtail shape comprising a forked end having two sidewalls tapered back towards the first segment. Light that would otherwise be lost at the slab/waveguide interface is instead captured by the tapered waveguide which laterally channels the light back into the waveguides thus mitigating insertion loss.

    摘要翻译： 锥形波导改善了在光学阵列波导光栅（AWG）的平板/波导界面处发生的插入损耗。 锥形波导具有两个段。 第一段从第一厚度减小，最接近AWG的板坯到距离板坯移动的第二厚度。 第二段具有等于第一段的第二厚度的基本恒定或均匀的厚度。 第二段也可以具有燕尾形状，其包括具有朝向第一段渐缩的两个侧壁的叉形端。 否则将在平板/波导界面处丢失的光替代地由锥形波导捕获，该锥形波导横向地将光引导回到波导中，从而减轻插入损耗。

    摘要： A light-pipe array system is provided. The system comprises a light projector that projects light, and a light-pipe array. The light-pipe array comprises a plurality of light-pipes. Each light-pipe comprises a dielectric transparent to the light, and an electrically conductive light barrier layer surrounding the dielectric. The barrier layer guides the light from an entrance of the dielectric surrounded by the barrier layer to an exit of the dielectric surrounded by the barrier layer. Each light pipe also comprises a light-receiving element that increases throughput of the guided light transmitted within the barrier layer via the dielectric. In one embodiment, the light-receiving element comprises an electrical conductor positioned along a central longitudinal axis of the dielectric. In another embodiment, the light-receiving element alternatively comprises a focusing element. The guided light transmitted within the barrier layer via the dielectric is used in fabricating photosynthesized bio-materials such as, for example, oligonucleotides.

    摘要： Optical gratings are fabricated on a scale that may be smaller than the resolution of the lithographic system used to generate the grating pattern. Parallel ridges are formed using lithographic techniques. A conformal deposition and anisotropic etch are then used to form sidewalls on the sides of the ridges. After removing the ridges, the remaining sidewalls are used as a mask to etch the substrate. Removing the sidewalls leaves the desired grating pattern, with a pitch spacing of one-half that of the original ridges.
