摘要： A block of composite material includes a dielectric material with a dielectric constant of .epsilon..sub.d =4.66 and which is at least 4 .mu.m thick and has electrically conductive microparticles randomly distributed throughout. The composite material exhibits an optical bistability without cavity feedback. The microparticles must be nearly uniform in size and of spherical diameter much smaller than the wavelength of light in the particle. The composite, when illuminated by laser light in the range of 500 nm and of varying intensity, becomes opaque at a critical input intensity and stays opaque until the input intensity reaches a certain level both below and above the intensity at which it initially became opaque. Thus the material behaves as an optical switch and a limiter.

摘要： An optically bistable, nonlinear optical device that produces an output that follows two hysteresis loops for an optical intensity variation input at a given frequency. One hysteresis loop follows a clockwise path of development, the other follows a counterclockwise path when the input field or optical intensity is ramped to a large value and returned again to a small value. These features of the device are effectively engineered by controlling the temperature of the input and output faces of the device, allowing optical logic gating and multiplex operation.
摘要翻译： 一种光学双稳态非线性光学器件，其产生在给定频率处的光强度变化输入的两个滞后回路之后的输出。 一个磁滞回线遵循顺时针的显影路径，另一个跟随逆时针路径，当输入场或光强度斜升到一个较大的值并再次返回到一个小的值时。 通过控制器件的输入和输出面的温度，可以有效地设计器件的这些特性，从而允许光逻辑门控和多路复用操作。
