Abstract

A new measurement technique of optical fiber nonlinearity coefficient is proposed. This technique is settled numerically utilizing the general small-signal analysis for nonlinear dispersive optical fiber. It is shown that for moderate power the first dip frequency of intensity modulation fiber transfer function scales linearly with optical power at the fiber input, and a linear scaling between the rate of dip frequency increase with the optical power and the fiber nonlinearity coefficient is observed. Using these properties, measurements of the frequency of the first dip at low and moderate optical power at the fiber input allow us to calculate the rate of dip frequency increase with the optical power and, from this, the fiber nonlinearity coefficient.
