中文摘要：
依据耦合模理论分析了双包层多芯光子晶体光纤的超模模场特性,通过倏逝波对7束光的相位调节,可实现相干合成,激光亮度得到很大提高.利用相干合成原理对双包层多芯光子晶体光纤的出射光相干功率密度进行了分析与测量,对此种结构的光子晶体光纤实现自相干合成提出了理论和实验依据。
英文摘要：
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.
