摘要： A chip-scale, air-clad semiconductor pedestal waveguide can be used as a mid-infrared (mid-IR) sensor capable of in situ monitoring of organic solvents and other analytes. The sensor uses evanescent coupling from a silicon or germanium waveguide, which is highly transparent in the mid-IR portion of the electromagnetic spectrum (e.g., between λ=1.3 μm and λ=6.5 μm for silicon and λ=1.3 μm and λ=12.0 μm for germanium), to probe the absorption spectrum of the fluid surrounding the waveguide. Launching a mid-IR beam into the waveguide exposed to a particular analyte causes attenuation of the evanescent wave's spectral components due to absorption by carbon, oxygen, hydrogen, and/or nitrogen bonds in the surrounding fluid. Detecting these changes at the waveguide's output provides an indication of the type and concentration of one or more compounds in the surrounding fluid. If desired, the sensor may be integrated onto a silicon substrate with a mid-IR light source and a mid-IR detector to form a chip-based spectrometer.
摘要翻译： 芯片尺寸的空气包层半导体基座波导可用作能够原位监测有机溶剂和其他分析物的中红外（中红外）传感器。 传感器使用来自硅或锗波导的衰减耦合，其在电磁光谱的中红外部分中是高度透明的（例如，对于硅，λ=1.3μm和λ=6.5μm，λ=1.3μm和λ= 12.0 用于锗），以探测波导周围的流体的吸收光谱。 将中红外光束发射到暴露于特定分析物的波导中，由于周围流体中的碳，氧，氢和/或氮键的吸收而导致衰减波的光谱分量的衰减。 在波导的输出处检测这些变化提供了周围流体中一种或多种化合物的类型和浓度的指示。 如果需要，传感器可以用中红外光源和中红外检测器集成到硅衬底上，以形成基于芯片的光谱仪。

摘要： The invention provides a waveguide with a waveguide core having longitudinal sidewall surfaces, a longitudinal top surface, and a longitudinal bottom surface that is disposed on a substrate. An interface layer is disposed on at least one longitudinal sidewall surface of the waveguide core. A waveguide cladding layer is disposed on at least the waveguide core sidewall and top surfaces, over the interface layer.

摘要： A method for enhancing photoluminescence includes providing a film disposed over a substrate, the film including at least one of a semiconductor and a dielectric material. Light emission may be activated by thermal annealing post growth treatments when thin film layers of SiO2 and SiNx or Si-rich oxide are used. A first annealing step is performed at a first temperature in a processing chamber or annealing furnace; and, thereafter, a second annealing step is performed at a second temperature in the processing chamber or annealing furnace. The second temperature is greater than the first temperature, and the photoluminescence of the film after the second annealing step is greater than the photoluminescence of the film without the first annealing step.

摘要： An optical waveguide structure includes an air-via region that receives an optical signal from an optical source. A photonic crystal cladding region is formed on the surface of the air-via region. The photonic crystal cladding region confines the optical signal within the air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of the optical signal.
