Abstract :
Wavelength-dependent pulse dispersion in germanium- and phosphorus-doped silica fibres of different concentrations was measured using mode-locked subnanosecond pulses in the 1.064¿1.55 ¿m wavelength range. Zero dispersion for GeO2-SiO2 fibres was observed in the 1.3¿1.33 ¿m region depending on the concentration. P2O5-doped silica fibres showed zero dispersion near 1.28 ¿m, independent of doping concentration.
