The effective optical nonlinearity of semiconductor quantum dots can be enhanced in one-dimensional photonic crystal structures. We have fabricated a one-dimensional photonic crystal with a structural defect which is made of CdSe quantum dots. Besides the enhancement of degenerate four-wave mixing efficiency, a fast response of transient population grating in an order of a picosecond was obtained in the one-dimensional photonic crystal. This structure can be used as a future photonic device with high nonlinearity and fast response.
