Researchers show that dispersed functionalized graphene can exhibit broadband nonlinear optical absorption at fluences well below the damage threshold. An optical energy-limiting onset benchmark of 10 mJ cm−2 at a linear transmittance of 70% was ob

Tuning the Optical Response of Photonic Bandgap Structures.
We demonstrate three ways in which the optical band-gap of 2-D macroporous silicon photonic crystals can be tuned. In the first method the temperature dependence of the refractive index of an infiltrated nematic liquid crystal is used to tune the hig

Femtosecond pump–probe reflectivity and second-harmonic spectroscopy experiments are used to investigate the optical tuning of leaky modes in a two-dimensional GaAs photonic-crystal waveguide. For above bandgap excitation with 270 fs, 800 nm pulses
