The Relation between the Nonlinear Coefficient of PCF and Its Geometry Parameters and the Optical Wavelength
光子晶体光纤非线性系数与其结构参量及光波长的关系

The relation between the nonlinear coefficient and the geometry parameters is derived in PCF of TIR type with triangle cladding . The curves showing this relation are presented. The relation between the nonlinear coefficient and the wavelength of the light propagating in PCF is also deduced. The curve about the relation of the nonlinear coefficient and the wavelength shows that this type of PCF has a very high nonlinear coefficient at the short-wave band, which can be potentially applied in many aspects.
