Source: ResearchGate Understanding Effective Nonlinear Coefficients in Photonics Kerr Nonlinearity in Optical Fibers In optical fibers, the Kerr nonlinearity leads to effects like self-phase modulation, where the phase of light changes with intensity. An effective nonlinear coefficient is used to quantify this nonlinearity. It is crucial in phenomena like the evolution of ultrashort pulses in […]
