Sub-wavelength modulation of χ(2) optical nonlinearity in organic thin films
Materials with spatially modulated nonlinear optical properties are used for quasi-phase matching. Here, Yanet al. exploit the nonlinearity of intermolecular charge transfer states together with oblique-angle deposition to achieve nanoscale modulation of the second-order susceptibility.
