The suspended-core fluoride fiber was fabricated by rod-in-tube method associated with casting method. Visible dispersive wave (DW) was obtained and tunable Raman soliton pulses from 1680 nm to 1960 nm were generated in the suspended-core ZBLAN fiber pumped by a 1560 nm femtosecond fiber laser. 0.685 W supercontinuum (SC) generation from 350 to 2400 nm is obtained with a launched pump power of 2.2 W. The dispersion-engineered ZBLAN fibers are excellent hosts for ultraviolet to MIR nonlinear optics and SC generation.
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.
