Variable delays in fiber optic optical transmission have been achieved by using photochromic- doped sol-gel silica glasses. Gaps between two commercial fibers in V-groove connectors, when filled with these materials, produce variable propagation times. Variations of the optical propagation time depending on the input power, wavelength, and dopant concentration are shown.
