Abstract

We report a supercontinuum of high polarization extinction ratio (PER) generated from a birefringent photonic crystal fiber (PCF). The zero dispersion wavelength of the fiber is calculated to be around 1.06μm. The pump source is a linear polarized femtosecond ytterbium-doped fiber laser. The SC performance with the pump pulse linear polarized both along the fast and slow axis of the PCF is studied. The SC ranging from 470nm to 2040nm has an all-spectral PER of -15.5dB, and the corresponding maximum output power is ~1W.
