New measurement technique of nonlinearity coefficient of optical fibre using fibre transfer function

We present a novel measurement technique of nonlinearity coefficient of optical fibre, the nonlinearity coefficient is evaluated by fitting of a new fibre transfer function which takes into account the fibre dispersion and nonlinearity. We present a novel measurement technique of the nonlinearity coefficient of optical fibre using the fibre transfer function. A new fibre transfer function which takes into account the group velocity dispersion (GVD), nonlinearity and loss of optical fibre is used to obtain the fibre nonlinearity coefficient by fitting to experimental data.
