QELS.We present measurements of the signal and group velocities for chirped optical pulses propagating through a GaAs cavity. Even when measured group velocity becomes negative the measured signal velocity is always less than c/n.2 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
