The technology and application of novel passive and active fiber optic devices will be investigated. Research in passive devices will build upon the recent discovery that dielectric mirrors can be produced in a continuous length of silica fiber by fusion splicing. The interdiffusion process which occurs when the mirrors are produced will be studied for a variety of candidate materials. Multilayer films will be used to obtain high reflectance. Novel input-output couplers and in-line polarizers will be produced using angled mirrors. Fabry- Perot interferometers in single-mode fiber will be explored for application as temperature and strain sensors. Feedback from fiber mirrors will be used for diode laser frequency stabilization, line narrowing and mode locking. Acoustooptic phase modulators in which the fiber itself serves as a cylindrical acoustic resonator will also be investigated. A zinc oxide transducer on the fiber surface will be driven from an rf signal source to produce a standing acoustic wave which modulates the guided light via the strain-optic effect. A coherent communication demonstration will be carried out using these modulators.

将研究新型无源和有源光纤器件的技术和应用。 无源器件的研究将建立在最近发现的基础上，即可以通过熔接在连续长度的石英光纤中生产介电镜。 将对各种候选材料研究生产镜子时发生的相互扩散过程。 将使用多层膜来获得高反射率。 新型输入输出耦合器和串联偏振器将使用斜镜生产。 将探索单模光纤中的法布里-珀罗干涉仪作为温度和应变传感器的应用。 来自光纤镜的反馈将用于二极管激光器频率稳定、线窄化和锁模。 还将研究光纤本身充当圆柱形声谐振器的声光相位调制器。 光纤表面上的氧化锌传感器将由射频信号源驱动，产生驻声波，通过应变光学效应调制引导光。 将使用这些调制器进行相干通信演示。
