Slow photon effect
Webb25 mars 2012 · Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. Here, we unambiguously distinguish these two nonlinear optical effects and identify both real and imaginary parts of the complex nonlinear refractive index of graphene. We show that … Webb1.2 Slow Photons and Photonic Crystals To clarify how PCs can enhance photocatalytic processes, including H2generation, some back- ground information on PCs and how they interact with light is necessary.
