Paper Abstract

The major use of tapered fibers is the in-line all-fiber spectral filters. Tapered filters are fabricated from a single piece of single-mode optical fiber that is heated and tapered until a given non-uniform longitudinal profile is obtained. This profile creates modes coupling with only forward propagating cladding modes. It is shown that tapered fibers induce low loss, low dispersion and low polarization dependence. The temperature sensitivity can be controlled by an appropriate packaging technique. Their main applications are the gain flattening filters, ASE noise suppression filters and spectrum correctors.
