Abstract

The dispersion uniformity of a commercially available and a custom-fabricated photonic crystal fiber (PCF) was characterized with a white light interferometry (WLI) setup between 900 - 1100 nm. The custom-fabricated PCFs displayed up to 1.5 times less variation in β2 and β3 for neighboring 50 cm long pieces and the largest variation between two 50-cm long pieces within a 5m long fiber section. As changes in dispersion can be caused by fabrication tolerances, this can be regarded as an effective metric to evaluate fiber fabrication uniformity.
