Solutions of polycarbazolyldiacetylene in benzene were studied using ultrabroadband sub-10-fs excitation pulses obtained from a visible optical parametric amplifier. The semiconducting polymers exhibited a steep onset of ground state absorption. The differential transmission signal was observed to be dependent on pump-probe delay at the probe...

We experimentally demonstrate a self-organized metasurface with a polarization dependent transmittance that can be dynamically controlled by optical means. The configuration consists of tightly packed plasmonic nanowires with a large dispersion of width and height produced by the defocused ion-beam sputtering of a thin gold film supported on a...
