This effort provides new approaches to optical computation. This is based upon the direction in which an electric field points in a thin film material. If this involves a periodically layered material structure such as that consisting of alternating Gallium arsenide and Gallium arsenide with aluminum added, then this so-called polarization switching can be enhanced (ie done in a smaller amount of material). It is this aspect which is new. With the field direction pointing in a specified direction, say across the film, a one is represented; parallel to the film, a zero. Thus binary states can be fit into such a polarization switching mechanism. This is interesting since this naturally leads to binary logic implementation. The effort in this proposal is thus directed towards optical signal processing using new data processing devices fabricated in semiconductor materials.

这一努力为光学计算提供了新的方法。 这 是基于电场指向的方向 薄膜材料。 如果这涉及到周期性分层 材料结构，例如由交替的镓 砷化物和砷化镓与铝添加，然后这个 可以增强所谓的偏振切换（即， 少量的材料）。 这方面是新的。 磁场方向指向一个特定的方向， 在整个电影，一个代表;平行于电影，一个 零. 因此，二元态可以适合于这样的极化 切换机制 这很有趣，因为这自然 导致二进制逻辑实现。 因此，本提案中的努力针对光学 使用新制造的数据处理器件的信号处理 半导体材料
