Abstract

The dispersion of femtosecond pulses in hollow fibers is discussed. The dispersion of the fundamental hybrid mode is small and approaches the material dispersion of the core-filling gas, as the core radius is increased. When multiple modes propagate, the modal dispersion causes considerable pulse spreading, which depends on the core radius. Pulse spreading due to modal dispersion in a straight fused-silica hollow fiber is measured experimentally and shown to agree well with the calculated value.
