Abstract :
This work presents non-degenerate pump-probe experiments on a silicon woodpile photonic crystal. The pump tunes through half the electronic band gap (EG) of Si, and the probe through the blue stop gap edge, as shown by the boxes. The crystal is switched by exciting free carriers via two-photon absorption, and the dynamics of the stop gap is probed at time Deltat after the pump.
