摘要： Fiber draw synthesis process. The process includes arranging reactants in the solid state in proximate domains within a fiber preform. The preform is fluidized at a temperature below the melting temperature of the reactants. The fluidized preform is drawn into a fiber thereby bringing the reagents in the proximate domains into intimate contact with one another resulting in a chemical reaction between the reactants thereby synthesizing a compound within the fiber. The reactants may be dissolved or mixed in a host material within the preform. In a preferred embodiment, the reactants are selenium and zinc.

摘要： In one aspect, the disclosure features an article, including a fiber waveguide extending along a waveguide axis, the fiber waveguide including a core extending along the waveguide axis and a confinement region surrounding the core. The confinement region is configured to guide radiation at a first wavelength, ? 1 , along the waveguide axis and is configured to transmit at least some of the radiation at a second wavelength, ? 2 , incident on the confinement region along a path, where ? 1 and ? 2 are different. The core includes a core material selected to interact with radiation at ? 1 to produce radiation at ? 2 .

摘要： The invention provides an optical fiber photodetector including a photoconductive element, such as a semiconducting element, having a fiber length. The semiconducting element is characterized as a non-composite material in at least one fiber direction. At least one pair of conducting electrodes is in contact with the semiconducting element along the fiber length, and an insulator is provided along the fiber length. An optical resonator can be disposed along the fiber length and along a path of illumination to the semiconducting element. The resonator is demensioned to substantially reflect all illumination wavelengths except for a prescribed range of wavelengths transmitted to the semiconducting element. The fiber photodetector can be arranged in a photodetecting fiber grid, photodetecting fiber fabric, or other configuration for detecting incident illumination.

摘要： Transparent displays enable many usefiil applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light. Exemplary transparent scattering displays can be simple, inexpensive, scalable to large sizes, viewable over wide angular ranges, energy efficient, and transparent simultaneously.

摘要翻译：透明显示屏可实现许多用途应用，包括汽车和飞机的单机显示器以及眼镜和玻璃窗上的显示器。不幸的是，由有机发光二极管制成的透明显示器通常是昂贵且不透明的。头戴式显示器通常需要固定光源并具有有限的视角。而使用频率转换的透明显示器通常是无效率的。相反，本发明的透明显示器通过从具有窄带散射截面和小的吸收截面的共振纳米颗粒散射可见光来操作。更具体地，将图像投影到掺杂有选择性地散射图像波长的光的纳米颗粒的透明屏幕上产生在观察者可见的屏幕上的图像。因为纳米颗粒仅在某些波长处散射光，所以屏幕在环境光下几乎是透明的。示例性的透明散射显示器可以简单，便宜，可扩展到大尺寸，在宽角度范围内可观看，能量效率高，同时透明。
