“…11 Finally, OL by reverse saturable absorption was observed at 1315 nm in fullerene doped polyimides. 12 The observation of an efficient 2PA process at the wavelength  requires the design of chromophores with a linear absorption at least at higher wavelength than /2. In the present case for 2PA in the 1400-1600 nm range, target chromophores have to present an intense linear absorption at wavelengths larger than 700-800 nm.…”

International audienceDipolar and symmetrical heptamethine dyes featuring strong linear absorption in the near-infrared spectral range (700−900 nm) were prepared at a gram scale. X-ray crystallographic structure of the dipolar chromophore is described revealing the remarkable planarity of the polyenic chain due to the central ring of the molecule. These chromophores present promising nonlinear absorption properties at telecommunication wavelengths (1400−1600 nm): (i) significant two-photon cross-sections were measured using the femtosecond Z-scan method, and (ii) their exceptional solubility allows us to carry out an optical-limiting experiment at 1500 nm in the nanosecond regime. In this regime, experimental data were interpreted on the basis of two-photon absorption (2PA) and 2PA-induced excited-state absorption (ESA). Finally, these systems, which present a lot of relevant properties (significant nonlinear absorption properties, two-step gram scale synthesis, high solubility, good thermal stability, and several sites of functionalization), open the way to numerous practical applications in biology, solid-state optical limiting, and signal processing

“…As an example, significant OL at 1300 nm has been reported for some chromophores, 20 while composites of fullerene-doped polyimides have been also found presenting OL at 1315 nm. 21 More recently, OL has been reported for hydrothermally treated graphene oxide (GO) derivatives at 1560 nm. 22 Furthermore, large TPA cross sections that can lead to efficient OL have been determined at 1300 nm (for bis-dioxaborine polymethine-based materials, 23 at the spectral region 1200-1400 nm (in the case of fused azulene and oligomeric porphyrins) 24 and between 1200 and 1580 nm (for nickel bis(diothiolene) complexes).…”
