The supermodel mode field characteristics of double cladding multi-core photonic crystal fiber were analyzed with coupled-mode theory. Through the phase adjustment of evanescent wave on 7 beams of light, one can realize the coherent combination, by which the laser brightness is greatly enhanced. We analyzed and measured the coherent power density of the light emitted from the double cladding multi-core photonic crystal fiber using coherent combination theory, and provide the theoretical and experimental basis for this multi-core photonic crystal fiber to achieve self-coherent synthesis.
