Abstract

We have investigated the dispersion and birefringence of an irregularly microstructured fiber with an elliptic silica core and irregular airholes. The polarization-dependent output power through the fiber reveals two well-defined principal-axis modes despite the irregularity of airholes. The dispersion of the fiber is measured in the range of 680 to $1000\mathrm{nm}$ using the Mach–Zehnder interferometric technique with sub-10 fs laser pulses, which yield two zero dispersion wavelengths at 683 and $740\mathrm{nm}$ for the two principal modes, respectively. The birefringence measured using the wavelength scanning method is about 0.0055 at $800\mathrm{nm}$. It is also demonstrated that this irregularly microstructured fiber with high birefringence and short zero dispersion wavelength is useful for the one-octave-spanning supercontinuum generation suitable for an $f–2f$ interferometric system.
