Presidential Young Investigator Award: Photo Refractive Non-Linear Optics

非线性光学领域已经看到越来越多的关注，因为 与使用光波技术的信号处理相关。 由于光 光束之间的任何相互作用都必须通过这种 交互. 迄今为止表现出最大相互作用的晶体 是所谓的光折射晶体， 在这些研究中被广泛使用。 几项引人注目的发展 近年来，人们开始关注这一领域。 的 光学计算领域，光学神经网络领域， 用于校正光束失真的光学相位共轭 其中。这是一个有很大潜力的方向， 从所涉及的光学器件的角度和从 开发更好的材料。

The area of nonlinear optics has seen increasing attention because of relevance to signal processing using lightwave technology. Since light is uncharged any interaction between light beams must occur through such interactions. Crystals exhibiting the largest interactions thus far have been the so-called photo-refractive crystals and have consequently been very widely used in such studies. Several striking developments have occured in recent years to focus attention upon this area. The area of optical computing, that of optical neural networks, and that of optical phase conjugation to correct distortion of optical beams are among these. This is a direction with a lot of potential both from the point of view of the optics involved and from the point of view of the development of better materials.
