Strained Layer Superlattice Heterostructures for Integrated Optical Logic Computation

这一努力为光学计算提供了新的方法。这是基于电场在薄膜材料中所指向的方向。如果这涉及周期性的层状材料结构，例如由交替添加铝的砷化镓和砷化镓组成的材料结构，则可以增强这种所谓的极化切换(即在较少的材料中进行)。正是这方面是新的。如果场方向指向指定的方向，比如穿过胶片，则表示为1；平行于胶片，表示为0。因此，二进制态可以适合于这样的偏振切换机制。这很有趣，因为这自然会导致二进制逻辑实现。因此，本提案中的努力针对使用在半导体材料中制造的新数据处理装置的光学信号处理。

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.
