We investigate the nonlinear optical properties of graphene flakes using four-wave mixing.
The corresponding third-order optical susceptibility is found to be remarkably large and only …

We critically analyze reported measured values of the third-order nonlinear optical
susceptibility χ (3) of bulk gold. Reported values of this quantity span a range of more than …

Adv. Mater. 2011, 23, 5540–5544 in Figure 2 b. While the 50 nm thick unstructured gold film
shows only very small changes of transmissivity at this intensity, the structured metamaterial …

Overcoming the challenge of growing ultrathin metallic films is of great importance for
practical applications of nanoplasmonic structures. In the present work, epitaxial, ultrathin (< …

Nonlinear propagation of light in a graphene monolayer is studied theoretically. It is shown
how the large intrinsic nonlinearity of graphene at optical frequencies enables the formation …

Spontaneous Raman spectroscopy is a powerful characterization tool for graphene
research. Its extension to the coherent regime, despite the large nonlinear third-order …

The nonlinear optical properties of metal Au and Ag colloidal solutions prepared by the
chemical reaction method were investigated by a single beam Z-scan technique. Under CW …

Nanophotonic devices offer an unprecedented ability to concentrate light into small volumes
