9361852 Mendoza The commercial realization of the promise of integrated optics technology depends on the establishment of a cost-effective, reliable method of fabricating active and passive waveguiding structures in a thin film format. Physical Optics Corporation (POC) proposes to investigate the development of a novel photolithographic technique that uses commonly available materials, and straightforward processing, to produce both active and passive waveguides in silica-based sol-gel films. The proposed technique offers the possibility of "writing" permanent index variations of up to 0.1 into the silica matrix. Furthermore, the same technique can be used to produce waveguides with nonlinearities in refractive index and transmissivity. During the proposed Phase I effort, POC will prove the practicality of this technique by using it to generate examples of planar waveguides, channel waveguides, and active and passive devices such as splitters, combiners, directional couplers, and Mach-Zender interferometers on a single glass substrate. ***

集成光学技术的商业实现取决于建立一种成本有效的、可靠的方法来制造薄膜形式的有源和无源波导结构。 物理光学公司（POC）提出研究一种新的光刻技术的发展，该技术使用常用的材料和简单的加工，在硅基溶胶-凝胶膜中生产有源和无源波导。 所提出的技术提供了可能性的“写入”永久指数变化高达0.1到二氧化硅矩阵。 此外，相同的技术可以用于产生具有折射率和透射率的非线性的波导。 在拟议的第一阶段的努力，POC将证明这种技术的实用性，用它来生成平面波导，通道波导，有源和无源器件，如分离器，组合器，定向耦合器，马赫-曾德尔干涉仪在一个单一的玻璃基板的例子。 ***
