Abstract
A novel method for characterizing the nonlinearity of all-optical sampling is proposed based on the normalized transfer function. Simulation results demonstrate the effectiveness of our method. Furthermore, an all-optical sampling experiment is performed to verify our method. Both simulation and experiment show consistency between our method and the measurements. The method only requires normalization and polynomial fitting of the transfer curve, and enables direct expression of the nonlinearity with the coefficients of the normalized transfer function.
