This small business innovative research Phase I project proposes a new method for electro-opticcontrol of light on planar waveguides. Currently, electro-optic control of light on silica-on-siliconplanar optical waveguides is by the thermo-optic effect, which is slow, consumes high power and exhibits a small effect. The new method provides unprecedented levels of optical phase delay, requires low power and moderate voltages, and exhibits response times under 10 microseconds. The method can be used to steer beams, tune waveguide gratings and control coupling between channels, thus enabling a new class of integrated electro-optic devices on silicon substrates. The Phase I project will demonstrate a large electro-optic modulation index and demonstrate a waveguide beamsteer with 10 degrees of steering capability within the waveguide. It will also explore methods of manufacturing integrated optical circuits using this technology. Phase II will design and build an integrated optic such as a waveguide Fourier transform spectrometer, barcode scanner, or CD/DVD pickup with dynamic tracking and focusing.Commercial applications of this technology include waveguide spectrometers for chemical sensing, identification of solvents and plastics, and mobile emissions monitoring. Other commercial applications include barcode scanners, CD/DVD optical pickups, free-space optical communications, beamsteering for angle-multiplex holographic data storage, and optical interconnects for computer backplanes.

这个小型企业创新研究第一阶段项目提出了一种新的方法，用于平面波导上的光的电光控制。目前，硅基二氧化硅平面光波导上的光的电光控制是通过热光效应，这是缓慢的，消耗高功率并且表现出小的效果。新方法提供了前所未有的光学相位延迟水平，需要低功率和中等电压，并表现出10微秒以下的响应时间。该方法可用于引导光束，调谐波导光栅和控制通道之间的耦合，从而使一类新的集成电光器件在硅衬底上。第一阶段项目将展示一个大的电光调制指数，并展示一个波导波束转向与10度的转向能力的波导内。它还将探索使用该技术制造集成光学电路的方法。第二阶段将设计和制造集成光学器件，如波导傅里叶变换光谱仪、条形码扫描仪或具有动态跟踪和聚焦功能的CD/DVD拾取器。该技术的商业应用包括用于化学传感、溶剂和塑料识别以及移动的排放监测的波导光谱仪。 其他商业应用包括条形码扫描仪、CD/DVD光学拾取器、自由空间光学通信、用于角度复用全息数据存储的光束控制以及用于计算机背板的光学互连。
