Octave spanning supercontinuum in soft glass equiangular spiral photonic crystal fiber

We present results for a broadband supercontinuum spanning almost two octaves (575 nm - 1600 nm) generated in an equiangular spiral photonic crystal fiber proposed earlier. The pump source is taken to be Yb - doped fiber laser at 1.06 μm. The fiber has two zero dispersion wavelength (at 885 nm and 1115 nm) with very high nonlinearity ( >5580 W-1 km-1 at 1060 nm).
