All-optical devices, in which one beam of light controls another, would make possible such applications as fast optical logic, optical amplifiers, and computers with massively parallel architectures. We report on advances in making single mode polymer optical fiber with nonlinear-optical cores, optical loss measurements, beam confinement and imaging studies, and nonlinearity measurements. Aside from all-optical devices, polymer-optical fibers can be used to make a new class of devices such as optical actuators and self-stabilizing positioners. Such devices rely on the fact that the length of a material can change in the presence of high intensity light in direct analogy to light induced refractive index changes. We show that fast fiber length changes can be induced with high power pulsed lasers. Furthermore, by combining photomechanical effects with feedback, we show that smart optical stabilizers can be fabricated. Such a device is demonstrated using the lower thermal effects and a low-power continuous wave laser.
