摘要
An all-optical tunable narrow-band filter with an ultrafast response time of 10 ps is realized in a two-dimensional nonlinear polystyrene photonic crystal. The pump and probe scheme is adopted to measure tunability based on the picosecond optical Kerr effect. The passband of the photonic crystal filter shifts about 4 nm under excitation of 14.7 GW/cm(2) pump intensity, which is in agreement with the theoretical prediction.
