Estimation of Kerr Nonlinearity in an Anti -resonant HollowCore Fiber by High -order QAM Transmission

We propose a novel technique to measure Kerr nonlinearity in a hollow -core fiber based on nonlinear phase shift estimation by high-order QAM transmission. The measured nz,Ker, of the NANF-5 medium is <2.20 x 10(-23) m(2)/W. (c) 2023 The Author(s)
