Abstract：A seven-core photonic crystal fiber (PCF) is fabricated and shown to possess a Gaussian-like far-field-intensity distribution. The seven-core PCF, designed with double-cladding structure and zero dispersion wavelength at 927 nm, is utilized to build up a 104 W all-fiber-integrated supercontinuum (SC) source with total conversion efficiency up to 74.3%. The average output power of SC can be further scaled based on this multi-core PCF.
