摘要：

We describe a new femtosecond time division interferometry technique for characterizing nonlinear index changes from different components of the chi(3) tensor. Pump probe interferometric measurements of nonlinear phase are performed using a time division multiplexed reference pulse. The n2 parallel-to and n2 perpendicular-to components of the nonlinear index are measured by permuting the polarizations of the pulses and using a novel differential detection and modulation scheme. Measurements are demonstrated in an optical fiber.
