Impact of Fundamental Mode Nonlinearity Confinement Adjusted by Structural Parameters of TIR-PCF With Six-fold Rotation Symmetry (C6v)
C6v对称TIR-PCF结构参量对基模非线性系数的影响数值研究

The influence of fundamental mode nonlinearity confinement with structural parameters of TIR-PCF with six-fold rotation symmetry at 1.55 μm was studied numerically by multipole method.The numerical results indicate that the fundamental mode nonlinearity confinement have close relation to the number of the air hole layers,the air hole diameter,the hole space and relative hole diameter.When the number of the air hole layers and the hole space are fixed,the fundamental mode nonlinearity confinement increases with the increase of the air hole diameter.Also when the number of the air hole layers and the hole diameter are fixed,the fundamental mode nonlinearity confinement decrease with the increase of the hole space.And,the fundamental mode nonlinearity confinement decrease as the magnification increases when number of the air hole layers and the relative hole diameter are fixed.
