We have demonstrated that polymer optical fiber can be built into smart photomechanical devices that have the ability to sense strain and to make mechanical adjustments accordingly. The first bulk device demonstrated is an all optical vibration stabilizer that is capable of keeping the position of a mirror fixed to within one part in 10exp 8. This device is unique in that no electronics are used light powers the device light acts as the sensing medium light carries the information the information is processed by light and the light is used to move the material by photomechanical action. We have also demonstrated that such a device can be miniaturized to sub-millimeter dimensions and that all the functions of the bulk device can be simultaneously imparted to one physical part of the device. Such devices can be connected in series or parallel to make ultrasmart associations that can be built into smart composite materials. Our devices have been patented and the technology is being transferred to industry.
