Paper Abstract

A signal analyzer is being developed that is based on a periodically tapped optical fiber. The spatial distribution of taps produces a waveform that is weighted by a spatial light modulator (SLM), optically Fourier transformed, and then detected with a video camera to continually display the power spectrum of the signal propagating in the fiber. The analyzer resolution and bandwidth is dependent on the distribution and number of taps. Taps have been formed in the core of fibers using UV light. Both single step beamsplitter and localized phase grating taps have been generated. Bragg grating taps tilted at 45 degrees with respect to the fiber axis were generated in order to diffract light directly out of the side of the fiber.
