Abstract

We report efficient dynamic gratings in close-packed solids of CdSe nanocrystals. These gratings are formed on the subpicosecond time scale and have diffraction efficiencies up to 0.5% for film thicknesses of ∼0.5 μm. Nanocrystal solids combine the best features of inorganic semiconductors (large resonant nonlinearities and high photostability) and organic semiconducting polymers (chemical flexibility and tunability of optical properties by simple synthetic means). Additionally, nanocrystal solids allow precise control over the spectral position of the nonlinear optical response by simply varying the size of the nanocrystals used in fabricating the solid (quantum confinement effect).
