Modeling of Guided Wave Optical Components

高数据速率光纤通信系统的应用取得了重大进展。加工技术的发展导致了各种光导波和光电子元件的平面制造。材料技术的进步与光学中并行信号处理的便利性相结合，使人们对光学计算产生了浓厚的兴趣。然而，导波和光电器件的制造是一个复杂的问题。材料生长和微加工工艺的变化会影响其光学和电子特性，从而直接影响器件和系统的性能。虽然材料“常数”只能从测量中获得，但集成系统的设计必须以这样一种方式进行，即系统性能可以预测。计算模型，最终是计算机辅助设计，是必要的。加州大学圣地亚哥分校的研究人员将研究LiNbO3材料中组件的建模。研究折射率分布、电光折射率变化、无源和有源器件的计算模型，包括微波特性的影响和元件的系统表示。将与Crystal Technology和Westinghouse建立合作，以获得有关设备和计算技术的实验数据。机构支持是充分的，PI完全有资格开展研究。

Significant advances have been made in the utilization of high data-rate optical fiber communication systems. Developments in processing technology have led to the planar fabrication of various optical guided wave and opto-electronic components. Advances in material technology combined with the convenience of parallel signal processing in optics have sustained the interest in optical computing. However, the fabrication of guided wave and opto-electronic devices is a complex matter. Variations in material growth and microfabrication processes affect their optical and electronic properties which directly affect the performance of the devices and systems. While the material "constants" can only be obtained from measurements, the design of the integrated system must be done in such a fashion that system performance can be predicted. Computational models, eventually computer aided design, are necessary. Researchers at the University of California San Diego will investigate the modeling of components in LiNbO3 materials. Investigation will be made of computational models for index profile, electro-optical index change, and passive and active devices including the effects of microwave properties and system representation of the components. Collaboration will be established with Crystal Technology and Westinghouse for experimental data on devices and computational techniques. The institutional support is adequate and the PI is well qualified to carry out the research.
