The dimensionality dependence of optical nonlinearity in cuprates was investigated by sub-picosecond pump-probe transmission measurements in the near-infrared region. It was found that cuprates with one-dimensional Cu-O networks show nonlinearity one order of magnitude larger than that of conventional band semiconductors and picosecond relaxation of the excited state. In contrast, a two-dimensional cuprate shows one order of magnitude smaller nonlinearity and slower decay of the excited state, as well as picosecond relaxation. The possibility for application of the present material to all-optical switching devices is also discussed.

The crystal structures of a thiophene-based terpyridine ligand and its four zinc halide complexes had been discussed. The open-aperture Z-scan results showed that LZnBr2 exhibits the best two-photon absorption property, which is greatly superior to that of the free ligand L.
