摘 要: 提出了以硅为基质、以高折射率铋化合物为纤芯的多固体芯集束混合导引型光子晶体光纤(photonic crystal fiber, PCF)。该类光纤利用谐振反射作用限制和全内反射2种机制将传输光场约束在高折射率固体棒芯中。通过数值模拟分析了集束六芯六角形和集束八芯四方形2种光子晶体光纤的有效模场面积和非线性系数随泵浦波长及纤芯直径的变化规律,证明这种光纤同时具有等效的高非线性和大的有效模场面积,可以用于实现高功率频率变换。
关 键 词: 光学工程;多芯光子晶体光纤;高非线性;有效模面积;混合导引

Abstract: The novel cluster�solid�core hybrid�guiding photonic crystal fiber (PCF) is proposed, wherein the PCF is structured by the bismuth silicate glass cores with high refractive index and a silica base. Two light guidance mechanisms, the antiresonant reflecting effect and the total internal reflection, can act simultaneously on the light field in the PCF so that the guiding is only localized in the cluster�solid�core region. The relationship among the mode field areas of the cluster�six�core PCF and the cluster�eight�core PCF and the pump wavelengths and the core diameters are discussed by numerical simulation. The results show that the novel PCF designs have the advantages of equivalent high nonlinearity and large effective mode�field area, and can offer a significant potential in high�power frequency transform.
Key words: optical engineering; cluster�solid�core photonic crystal fiber; high nonlinearity; effective mode�field area; hybrid�guiding
