| 摘 要： | 设计了一种双芯高双折射光子晶体光纤，采用多极法（multipole method）和光纤的模式耦合理论研究了光纤的双折射、耦合长度以及色散特性.数值研究发现，对于空气孔节距 Λ=1.2 μm，空气孔直径d=1.0 μm的光纤，在1.55 μm处双折射度为1.24×10-2；对应x偏振模的耦合长度为21.6 μm，对应y偏振模的耦合长度为24.3 μm. 这种具有高保偏度和极短耦合长度的双芯光子晶体光纤对于微型光子器件的研制具有重

| Abstract: | A kind of dual-core high birefringence photonic crystal fibers (DHB-PCFs) has been proposed in this paper. The birefringence, coupling length and dispersion characteristics of DHB-PCFs have been studied by muhipole method using mode coupling theory. It is found that the birefringence of DHB-PCF with pitch 1.2 μm and air-hole diameter 1.0 μm is 1.24 × 10~(-)2in optical communication band of 1.55 μm wavelength. Correspondingly, dual-core coupling lengths are 21.6 μm and 24.3 μm for x-polarized mode and y-polarized mode, respectively. The DHB-PCF with high degree of polarization and very short coupling length is useful for manufacturing minitype photonic apparatus. |
