Abstract

Fiber optical applications are primarily limited by group-velocity dispersion. In single-mode fibers, material and waveguide dispersion yield a total chromatic dispersion where no modal influences occur. However, modal dispersion plays a significant role in multimode fibers, whereas waveguide dispersion is negligible. The concern of this report is the investigation of the dispersion properties of photonic crystal fibers, with both single-mode and multimode operation, using a time-frequency domain white-light Mach-Zehnder interferometer. The results demonstrate the possibility to separate different transverse fiber modes and, hence, to measure the material, waveguide, and modal dispersion of optical fibers.
