Nanostructured materials with tunable nonlinear optical response are of great interest for different applications in nanophotonics. In this work we report the results of a comprehensive study on the nonlinear optical properties of two kinds of plasmonic metamaterials, i.e., honeycomb nanoprism arrays and multilayer hyperbolic metamaterials, which proved to have a very rich spectrum of parameters (as metamaterials morphology and composition, wavelength and polarization of an input beam) to exploit for controlling their nonlinear response over a broad spectral range.

Linear Absorption

The linear absorption spectra and third-order nonlinear optical properties of M@ C 82 (M = Sc , Y , La ) nanostructural materials, whose configurations were optimized at the unrestricted open shell UB3LYP level, are simulated by the sum-over-states combined with the time-dependent UB3LYP methods. The obtained results show that the electronic absorption bands have redshifts, and the values of third-order nonlinear optical polarizabilities and two-photon absorption cross sections increase for M@ C 82 fullerenes (M = Sc , Y , La ) as the atomic radius of encased metal M increase in the order of Sc → Y → La . It is indicated that the electron-donating ability from the encased M atom to cage C 82 decreases or the electron-accepting ability from C 82 to M atom increases as the atomic radius of M increases, which results in third-order nonlinear optical response enhancement in the order of Sc @ C 82 < Y @ C 82 < La @ C 82. This gives a clue to design the nanostructural materials of encased fullerenes having a large nonlinear optical response.

The Way

Fluorographene has been recently shown to be a suitable platform for synthesizing numerous graphene derivatives with desired properties. In that respect, N-octylamine-modified fluorographenes with variable degrees of functionalization are studied and their nonlinear optical properties are assessed using 4 ns pulses. A very strong enhancement of the nonlinear optical response and a very efficient optical limiting action are observed, being strongly dependent on the degree of functionalization of fluorographene. The observed enhanced response is attributed to the increasing number of defects because of the incorporation of N-heteroatoms in the graphitic network upon functionalization with N-octylamine. The present work paves the way for the controlled covalent functionalization of graphene enabling a scalable access to a wide portfolio of graphene derivatives with custom-tailored properties.

The usage of a modified Z-scan setup for the study of optical nonlinearities of bis-phthalocyanines is discussed. The setup leads to the selection of the pure electronic nonlinear optical response purged from other possible contributions such as molecular reorientation or thermal effects. The described experimental method is based on the capability to extract the instantaneous nonlinear response of the sample, by monitoring and managing cumulative effects and taking full advantage of the large number of probing laser pulses. This kind of approach has been applied on some sandwich-type metal bis-phthalocyanines confirming its potential for an in-depth analysis of the nonlinear response of such molecules. First results on titanium, niobium and tin bis-phthalocyanines provide information on the role of the conjugation length in their nonlinear optical response.
