Abstract
We report on a new class of devices in which laser light is used to control the length of a material. To demonstrate these devices we have designed an all-optical circuit that, using feedback, allows us to control the length of a polymer optical fiber in three ways: stabilization, discrete positioning and continuous positioning. We also report the dependence of response time on fiber length. Many mechanisms long known to result in a refractive index change also result in a length change. For our circuit we have utilized the heating mechanism to control length. While this heating mechanism is relatively slow it is also relatively large in magnitude.
