摘要
A nonlinear phase shift is applied to a spectrum of an ultrafast input signal after dispersing it in space. It is shown that when the input is a pulse pair, the output contains new pulses, which are formed both in front of and behind the original pair. We show the analogy between this experiment and photon echoes and discuss the causal properties of this system.
