A double cladding seven-core PCF was presented for high
power supercontinuum generation. The calculated zero dispersion wavelength is
located at 912 nm, which has a good agreement with the measurement. The
attenuation is measured 6dB/km at 1590nm and lower than 14.5
dB/km at 1060nm, the water-loss peak at 1380nm is about 134dB/km;
Supercontinuum spanning over more than 1500 nm was generated when the designed
seven-core PCF was pumped by a gain-switching Yetterbium-doped fiber laser. These
results will be helpful in the future design of multicore photonic crystal
fibers (MCPCF) with proper guidance properties for high power supercontinuum generation.
