Intensity-Dependent Refractive Index Effects in Optical Fibers

光学计算手段的发展取决于材料和纤维能否以有用的方式与光波相互作用。这些用来以各种方式计算的函数不仅取决于这一点，而且同样重要的是非线性相互作用。这意味着从材料或光纤发出的光学光束不是简单地与材料或光纤输入端的光束强度成正比。特别令人感兴趣的是那些允许光束之间相互作用而没有其他可见迹象的材料，例如电流流动。本提案涉及这种相互作用及其对各种类型的光信号处理方案的潜在应用。

The development of optical means of computing depends upon the viability of having materials and fibers which can interact in a useful manner with lightwaves. Such functions as would serve to compute in various ways depends upon not only this but equally important a nonlinear interaction. This implies that the opÕical beam emitted from the material or from the fiber is not simply proportional to the strength of the beam at the input of the material or the fiber. Of particular interest are those materials which allow an interaction between optical beams without visible sign of other consequ>nces such as electronic current flow. The present(proposal deals with such interactions and their potential applications to various types of optical signal processing schemes.
